ABB Power Control Device Precautions

Precautions

Take the following precautions when using the Power Control Device (PCD):

1. Connect the current and voltage transformers for proper phase rotation and polarity to ensure correct measurement of kilowatts and kiloVARs, and for the proper operation of the 46, 67P and 67N protection elements.

2. Incorrect wiring may result in damage to the PCD, recloser and/or electrical hardware connected to the recloser. Be sure the wiring on the PCD and the recloser agree with the electrical connection diagram before energizing.

3. Apply only the rated control voltage as marked on the PCD nameplate.

4. High-potential tests are not recommended. If a control wire insulation test is required, only perform a DC high-potential test. Surge capacitors installed in the PCD do not allow AC high-potential testing.

5. Follow test procedures to verify proper operation. To avoid personal shock, use caution when working with energized equipment. Only competent personnel, familiar with good safety practices should service these devices.

6. When the PCD self-checking function detects a system failure, the protective elements are

disabled and the alarm contacts are activated. Replace the PCD as soon as possible.

WARNING: Terminals on the back of PCD may be energized with dangerous voltage levels. Use extreme care.

CAUTION: Do not insert hands or other foreign objects into the case for removal of PCD modules while energized.

1 Introduction

The Power Control Device (PCD) is an easy to use, powerful, microprocessor-based control unit that provides extensive recloser protection on distribution automation systems. The environmentally hardened unit combines control, monitoring, protection, reclosing elements and communication, in one economical package. Power quality, accurate metering, load profile and monitoring provide crucial system information for managing competitive distribution systems. Available for 5A- or 1A- secondary current transformers (CT), the PCD uses recloser 52A and 52B auxiliary contacts for logic input signals. The PCD can be applied with voltage transformers (VT) connected for operation at 69 or 120 volts AC phase-to-ground (wye), or 120 volts AC phase-to-phase (delta or open delta with phase B grounded).

The PCD empowers distribution automation solutions for the electric power system because it is equipped with DNP 3.0, Modbus®_{RTU, Modbus}®_{ASCII and IEC60870-5-101 communication}

protocols. The PCD operates remotely via these protocols using an auto-detect protocol algorithm that allows system reconfiguration, fault analysis and transfer of protection settings, making any distribution system more efficient. In addition, the PCD is equipped with a powerful data gathering capability to allow analysis of system loading, planning and upgrading. The integrated battery charger monitors and maximizes battery life and remote battery testing, and fault interruption accumulation simplifies maintenance planning and eliminates time-based maintenance procedures. All of these features save user time and resources.

The PCD provides the following features in one integrated package: • Local human-machine interface (HMI)

• Six front panel Light Emitting Diode (LED) status indicators for: Pickup, Lockout, Phase O/C, Ground O/C, USER 1 and USER 2

• USER 1 and USER 2 status indicators are user programmable • Large backlit 2 x 20 character Liquid Crystal Display (LCD)

• Simple menu-driven configurator for Meter, Settings, Records, Operations and Test using four arrow (◄ ► ▲ ▼), Enter and Clear pushbuttons

• LCD displays phase currents (IA, IB, IC and IN) during normal operation with P for Primary

Settings employed

• LCD displays fault information after a trip

• Front panel pushbuttons with red LED indicators for Remote Blocked, Ground blocked, Reclose Blocked, Alt 1 Settings, Counters, PROG 1 and PROG 2

• PROG 1 and PROG 2 are user programmable outputs • Hot Line Tag red LED with ON and OFF pushbuttons • Self Check LED, green means normal and red means fail • Front panel OPEN and CLOSE pushbuttons

• OPEN with green LED and CLOSE with red LED indicator

• Front-mounted isolated RS-232 data port for easy download and upload of data on-site • Two levels of password protected settings and controls

FRONT & REAR PANELS

2 Exploring the Front and Rear Panels

2.1 Front Panel HMI

The PCD HMI (Human Machine Interface) directly allows programming, interrogation and control of the recloser or circuit breaker. Figure 2-1 represents the current production front panel HMI for ANSI units. The changes included in the current version reflect substantial feedback from customers. Notably, the size of the LCD has been increased, the LCD temperature compensation improved, and the optical port has been replaced by a standard RS-232 port.

(22)

2 Exploring the Front and Rear Panels ABB Power Control Device

2

2.2 Status-Indication LED Targets

2.2.1 Pickup

The pickup indicates the value on either phase or neutral is above the minimum pickup setting as programmed in the PCD overcurrent elements. This indicator is only illuminated when the overcurrent condition is present.

2.2.2 Phase

O/C

The phase O/C is the target indicator for phase overcurrent trip. This indicator is latched on after a trip, and reset by pressing the “C” button once on the HMI, or by resetting the targets from SCADA.

2.2.3 Ground

O/C

Ground O/C is the target indicator for ground overcurrent trip. This indicator is latched on after a trip, and reset by pressing the “C” button once on the HMI, or by resetting the targets from SCADA.

2.2.4 Lockout

Lockout indicates the recloser/breaker has completed its programmed reclosing sequence, and has locked out with the recloser/breaker in the open position. It also illuminates when the recloser is opened manually. If using single phase tripping mode, refer to Section 11 for single-phase lockout indication.

2.2.5 Self

Check

Self-Check is an LED that indicates the functional status of the PCD. Green indicates the PCD has successfully passed its internal diagnostic test and is functioning properly. Red indicates the PCD has failed its internal diagnostic test. Whenever the Self Check red LED is illuminated, all protection elements are disabled, the Self-Test dedicated contact on the rear panel (on the PS or UPS module) will drop out, and alarm contacts are activated. Remove the faulty module from service and replace as soon as possible.

2.2.6 USER 1 and USER 2

The USER 1 and USER 2 LEDs located at the top, upper right corner of the HMI, are assigned to logical inputs using the Programmable Inputs menu in AFSuite. See 5.4.2 for further details on setting up these LEDs

2.3 Control Buttons with LED Targets

2.3.1 Remote

Blocked

Remote Blocked is enabled whenever the red LED is lit. During this time, no control or setting changes can be made through the rear communication port, including communication through AFSuite and SCADA.

The Remote Blocked condition can be enabled either by pressing the Remote Blocked pushbutton on the front panel or by using the Remote Blocked logical input (RBI). A logical output (RBA) can be mapped to a physical output using the programmable I/O (see Section 5).

(23)

2

Important: Exercise caution if using the Remote Blocked logical input in the programmable

mapping. Setting this will disallow further change of settings from the control if the contact is energized.

2.3.2 Ground

Blocked

When lit, Ground Blocked will disable all ground overcurrent elements (50N-1, 50N-2, 50N-3, 51N, 67N and Sensitive Earth Fault (SEF)). The Ground Blocked condition can be enabled using three different methods: (1) press the Ground Blocked pushbutton on the front panel, (2) use the Ground Torque Control logical input (GRD), or (3) use the SCADA Ground Block/Unblock data points. Any one of these procedures will turn on the front panel LED and enable the blocking.

2.3.3 Reclose

Blocked

Reclose Blocked control is used to disable the 79 (reclose) elements. The Reclose Blocked condition can be enabled three ways: (1) press the Reclose Blocked pushbutton, (2) use the recloser enable logical input (43A), or (3) use the remote (SCADA) 43A Block/Unblock points. The front panel LED will illuminate for any source of blocking.

It is important to note that the Reclose Blocked affects only automatic reclosing functions. Manual close operations, such as the front panel close, logical input close, and HMI menu selection close are not blocked by Reclose Blocked, though there is a SCADA point available to permit closing based on the status of the 43A logical input.

2.3.4 Alternate 1 Settings

The Alternate 1 setting is active when the ALT1 pushbutton is pressed and the red LED is lit. When this setting is active, A1 is displayed in the lower right corner of the LCD display. Alternate 1 settings can be enabled either by pressing the ALT1 settings pushbutton on the front panel or by using the Alternate 1 settings logical input (ALT1). This is conveniently used for storm or seasonal settings during maintenance operations.

Alternate 1 settings take priority over Primary Settings, i.e., alternate settings cannot be overridden by Primary settings. Likewise, Alternate 2 settings have priority over Alternate 1 settings. If Alternate 2 settings are activated by SCADA, a logical input, or by the Loop Control Module (LCM) (for units with the loop control option), they cannot be overridden by Alternate 1 or Primary settings.

If the PCD and the LCM are in a Mid-Point or Tie-Point loop control scheme, Alternate 1 settings may be enabled. The setting logic for this method is described in Section 12 of this manual.

Important note on Ground Blocked, Reclose Blocked, & Alternate Settings Buttons: The

front panel control buttons and remote control are mutually resetting, i.e., if block functions or alternate settings are set remotely, they can be overridden using the HMI. The opposite is also true: the remote source can clear a block set locally at the HMI. However, this is NOT true when using logical inputs (using the PCDs programmable logic feature). Activation of these functions using logical inputs cannot be overridden by remote or local sources.

2.3.5 SEF

Blocked

Units prior to the “Enhanced Front Panel” have an SEF (Sensitive Earth Fault) Blocked button. If applicable, when illuminated, the SEF element is blocked. The SEF Blocked control works essentially the same as the Ground Blocked, except it affects only the SEF element. The SEF Blocked condition can be enabled by pressing the SEF Blocked pushbutton on the front panel, using the SEF Blocked logical input (SEF), or activating the ground block function. The front panel LED will illuminate on any of these blocking sources.

(24)

2

2.3.6 Counters

Pressing the Counters pushbutton reports the status of the recloser/breaker operation counter (BrkrOp) and overcurrent trips (OC Trip). When activated from a key, the counters will appear in the LCD in alternating screens as follows:

When the unit is in three-phase mode as defined in Configuration Settings:

When the unit is in single-phase mode as defined in Configuration Settings:

The above information appears for 10 seconds and then the view returns to what was displayed before the Counters button was pressed. While the PCD displays the counters, the Counters LED remains on.

2.3.7 PROG 1 (Battery Test)

Pressing this pushbutton will initiate a battery test sequence (Section 2.5.3.6.1). The LED target will remain illuminated for the duration of the test.

2.3.8 PROG 2 (Phase Select)

For all PCDs with older versions of the HMI (e.g. without Hot Line Tag buttons on HMI) that are using firmware version 2.52 or higher, the PROG 2 function is enabled to report the status of the recloser/breaker operation counter. Refer to Counters (Section 2.3.6) for a functional description. In firmware version 3.0, the PROG 2 provides the ability to select a phase for manual independent phase trip or close. For this feature to be enabled, the following conditions must be met:

• The PCD control must have the single phase tripping option

• Configuration Settings > Trip Mode = “1 Phase”

• Configuration Settings > Prog2 Func. = “PhasSel” (default is “Disabled”)

When this criteria is met, the PROG 2 button will permit the selection of a phase for manual independent phase operation.

Press the PROG 2 button. “Operate Phase A” will appear in the LCD.

If you want to TRIP or CLOSE A phase, press the OPEN or CLOSE button while the desired phase is displayed.

If a different phase is desired, press PROG 2 again to advance to the B or C phase.

Pressing the Clear button, Enter button, or Counters button will exit the PROG 2/Independent phase select menu. Likewise, when in the PCDs menu, or when Counter information is being displayed, the PROG 2 button will be disabled.

When in Hot Line Tag mode, closing is disallowed.

2.4 Recloser/Breaker Status LED and Direct Controls

2.4.1 Close

Pressing the Close pushbutton sends a close signal to the recloser or circuit breaker. An additional setting allows a fixed time delay before closing the recloser or circuit breaker. This setting is accessible via the Configuration Settings menu. The Close Delay Time setting will allow a delay close of 0 to 250 seconds after pressing the Close button. A red LED adjacent to the Close button signifies the recloser or circuit breaker is closed. The Close button is disabled by the Hot Line Tag / Close Block (CLSBLK) function.

2.4.2 Open

Pressing the Open pushbutton sends an open signal to the recloser or circuit breaker. A green LED adjacent to the Open button signifies the recloser or circuit breaker is open.

2.4.3 Recloser Position LED

A blinking LED, alternating between red and green, indicates that the integrity of the 52A or 52B contacts is indeterminate, or that the recloser or circuit breaker is in a breaker failed state.

2.4.4 Hot Line Tag

Pressing the Hot Line Tag button activates the TAGBTN logical output. Programming to activate the CLSBLK logical input (and any other desired logical inputs) through Programmable I/O mapping is required. The associated LED for the Hot Line Tag button illuminates whenever the CLSBLK input is activated. Refer to Application Note 6 for details on programming the Hot Line Tag function.

2.4.5 LCD

The LCD of the PCD displays two lines of 20 characters.

High or low temperature extremes will affect the illuminated visibility of this display. In the event the display becomes unreadable, increase the LCD contrast by pressing the down-arrow key while the normal LCD display is in view (which displays the present load current values). The default contrast setting of the LCD can also be changed with a similar setting in the Configuration Menu of AFSuite.

The following displays and menus are available through the HMI:

Continuous Display—shows currents and which settings are enabled

Post-Fault Display—shows faulted elements, phase(s) and fault currents for last fault until targets are reset

Remote Tagging Message—When set to do Remote Tagging in the Programmable I/O, and tagging is activated by SCADA, will display “Warning: Remote Tag Applied”. Figure 2-2 shows an outline of all the menus available through the HMI.

2.4.6 Enter

Key

Press the Enter key first to enter the menu tree for displaying information or changing settings. To move down the menu tree to a sub-menu, scroll to the sub-menu name using the up and down arrow keys, and then press the Enter key. The Enter key also accepts a new setting value or records the choice selected using the left and right arrow keys.

(26)

2

2.4.7 Left and Right Arrow Keys

Use the left and right arrow keys to decrease or increase, respectively, a setting value or record number. Also, use them to move from left to right within the password string. Hold down or repeatedly press the arrow keys to change the setting value.

2.4.8 Up and Down Arrow Keys

Use the up and down arrow keys to move through the various menus and to change the character value when you enter the alphanumeric password.

When the LCD display is in normal view (which shows the present load-current values), press the down arrow key to increase the contrast of the LCD display and pres the up arrow key to reduce the LCD display contrast.

2.4.9 Clear

Key

Clear key usage:

• Return to the previous menu (i.e., move up the menu tree)

• Reset LED targets and the LCD display after a fault (push “C” once)

• Scroll through all metered values (push “C” twice). This menu scrolls through Demand Values, then Min/Max Demands, and lastly Load Values. To skip over any of these sets of values, press the “C” button again. After the last Load Value is displayed, the screen will return to the normal metered values.

• Reset the peak demand values (push “C” three times)

2.4.10 PCD System Reset

Simultaneously press the “C”, “E” and up-arrow keys to reset the system. This resets the microprocessor and re-initiates the software program. During a system reset, no information or settings are lost. In addition, the breaker will not operate upon a system reset as it only “reads” the position of the 52a/b switches.

2.4.11 RS-232 Serial Front Port

A RS-232 serial port on the front panel HMI is useful for connecting a PC to the PCD for data acquisition. This is an independent port from the rear panel port, and can be used for programming locally while the rear port remains on SCADA. The front port is fixed to 9600 baud and address 0.

2.5 Modules

2.5.1 Introduction

The PCD is packaged in a metal case suitable for conventional flush mounting in a pole-mounted cabinet. All connections to the PCD are made at clearly identified terminals on the rear of the unit. The PCD uses a six-slot card case with the slots defined as follows:

Slot A: PS or UPS

Slot B: VR Recloser Control DIO (Type 2) or DIO (Type 1) Slot C: DIO (Type 1) – if applicable

Slot D: CPU (Type 2)

Slot E: COM (Type 3, Type 4 or Type 5)

(29)

2

Figure 2-3. Typical Rear Panel

2.5.2 PS – Power Supply Module

The Power Supply (PS) module accepts only DC voltage. The PS module can only reside in the first slot (Slot A) of the PCD case. Depending on the PCD catalog number, the PS module is available for operation with three different voltage levels: 24 VDC, 48 VDC or 125 VDC. In addition, the PS module provides three binary output contacts, a self-check (Form C) relay output, and four binary input contacts. Each of the three binary output contacts have factory default settings for normally open (NO). Binary output 1 (Out 1) is programmable as a normally closed (NC) contact.

(30)

ground wire. Remove the two screws securing the PS module to the PCD housing. Insert a thin flat screwdriver along the right edge of the module and firmly wedge the screwdriver against the PCD case to slide the PS module out of the PCD case. With the PS module removed, locate a red jumper labeled “J1” on the printed circuit board; looking at the printed circuit board, the red jumper is vertically orientated. Carefully remove the orange jumper then re-insert with a horizontal orientation. Out 1a is now configured for NC output. Reinsert the PS module into the PCD housing, following the procedure in reverse order. Energize the PCD and verify Out 1a is now a NC contact.

Figure 2-4. PS - Power Supply Module

2.5.3 UPS – Uninterruptible Power Supply Module

The UPS is supplied on all AC powered units. In early 2004, three new modules have been introduced, each having a specific purpose and are identified as UPS Type 2 (UPST2), UPS Type 3 (UPST3), and UPS Type 4 (UPST4). Refer to Figure 2-5 for pin arrangements of all modules. The original UPS will herein be identified as UPS Type 1. For information on the UPS Type 1, refer to any manual prior to this issue.

The Uninterruptible Power Supply (UPS) module can only reside in the first slot (Slot A) of the PCD. The UPS module contains AC power input, 24/48 V battery charger, a 12/24 VDC auxiliary output, temperature sensor and self-check contact.

The UPS Module provides battery backup and maintenance functions for the PCD. Features include:

• Operation from an AC or DC input

• Supports 24 VDC or 48 VDC lead acid batteries

• Battery float voltage is temperature compensated for maximum battery capacity

• Battery temperature, voltage and charger currents are available for display via the PCD HMI • A battery test can be performed on request from the PCD front panel (PROG 1), via SCADA,

(31)

• Provides a status check single-pole-double-throw (SPDT) relay output

Figure 2-5. UPS - Uninterruptible Power Supply Modules

2.5.3.2 UPS Type 2, Type 3 and Type 4

The UPS Type 2 is primarily intended as a direct replacement/upgrade for the UPS Type1 (all legacy units). No other changes (control wiring or PCD firmware) are required. The most important new features are as follows:

• Universal AC/DC input ranges

• Addition of isolated 12/24V auxiliary output

(32)

2.5.3.2.2 AC/DC Input:

See the Table 2 for specific rating information for each type UPS.

The UPST2, UPST3 and UPST4 are designed to operate on a wide range of AC or DC inputs. Above this range, surge suppression devices will clear fuse F1. For low inputs the UPS will shut down non-critical features such as battery charge and battery test. For even lower inputs, the UPS will shut down the input and the UPS will power the PCD from the external battery. If operating without AC, if the battery is not available or it is depleted, the PCD will be powered down.

The Type 2 and Type 3 are intended to operate from nominal voltages in the 110VAC to 208 VAC range, or from a 250 VDC station battery. The module functions correctly at up to 265 VAC input and down to 90 VAC. For sustained voltages above 265 VAC, fuse F1 will blow. For voltages below 100 VAC battery charge is disabled. For sustained voltages below 90 VAC, the power supplies input converter will shut down and the lead acid battery will be used to power the PCD.

The Type 4 is intended for 125 VDC station batteries and for 90 VAC nominal power systems. For voltages above 150 VAC, F1 will blow. For voltages below 50 VAC, the power supplies input will shutdown and the lead acid battery will be used to power the PCD.

2.5.3.2.3 Auxiliary Output voltages

There are two types: Non isolated and isolated. Isolated Auxiliary Output:

The isolated auxiliary voltage is switch selectable for 12V or 24V. Both voltage settings can supply 8 W outputs. The output is protected by fuse F2. All UPST2/3 and 4 units ship with the isolated auxiliary voltage set to 12V.

The UPS or the PCD does not detect the isolated auxiliary voltage setting.

If the voltage is changed to 24V, a label clearly indicating 24V needs to be placed on the modules faceplate.

To configure the Isolated Auxiliary Output for 24V:

1. Remove the UPS from the PCD.

2. Move the J10 jumper from pins 1&2 to pins 2&3.

3. Place a “24V Isolated Aux” label on the faceplate.

4. Reinstall the UPS card.

5. Power up the PCD and verify the auxiliary output voltage.

2.5.3.2.5 Battery Functions

UPST2/3/4 modules support 24 or 48 V batteries (by build option). The basic features are: • Battery charge with charge voltage a function of temperature

• Operation off of the battery during AC input failure • Battery test

• Controlled shutdown of the PCD for low battery voltage Battery Charge:

Charge current for UPST3 and UPST4 modules peaks at 1 amp. The time to charge a 12 amp-hour battery bank is approximately one day.

Note on UPST2: Most UPST2 applications will be used with the external Capacitor Assist

Module (CAM). This external CAM will restrict battery charge to a trickle charge only. Battery charge times for UPST2 applications with the CAM will be unchanged from PCDs with the USPT1. Typically will require 8 days for full charge.

The battery charger only runs when the AC/DC input voltage is above a minimum level (see the summary), and when the UPSs internal temperature is not excessive.

The charge voltage is a function of ambient temperature, with the temperature sensed by an external thermistor. However, if the external thermistor is missing, the module’s onboard temperature is used for calculating the battery voltage.

Operation off of battery:

During AC/DC input failure, the UPS powers the PCD from the battery. The UPS then monitors the battery voltage and shuts down the PCD on a low battery condition (See Table 2).

Once the UPS has shutdown due to low battery voltage, the only way to restart the PCD is by restoring the AC/DC input or by pressing the battery start button (provided the battery voltage is an acceptable level.)

Note on UPST2: The battery start feature is functional on the UPS Type 2. However, most

UPST2 installations will include an external Capacitor Assist Module. This external module will defeat the battery start feature. With the CAM you must restore the AC/DC input to restart the PCD.

The UPS tests the battery when requested by the PCDs CPU card. The battery test simulates the energy draw similar to that for operation of a recloser. The request for a test can be manually or automatically generated. Battery test requests are refused under these conditions:

• Must have one minute cool down between tests • Loss of AC/DC input

• High ambient temperature 2.5.3.3 AC Input and Isolation

The AC input requires a nominal supply of 120 VAC at 80 VA maximum. The operating voltage range is -15% to +10%, or 102 to 132 VAC.

The AC power input is not internally isolated from the switched DC output, battery, or temperature sense terminals. Any connection between the AC power inputs and the other UPS terminals (except for the self-check relay outputs, which are fully isolated) will damage the UPS module. Unwanted connections can occur via a grounded battery, grounded load on the Switched DC Output, or during testing.

Note: The UPS module AC input power uses an isolation transformer. Use of a 120/240 V

dual-primary transformer affords the additional option of 240 VAC input from a voltage transformer, with 120 VAC input voltage to the PCD.

2.5.3.4 Startup

With proper AC voltage applied to the UPS AC input, the UPS module automatically begins operation. However, if no AC voltage is present and the UPS module is connected to a charged battery, the UPS does not start automatically. This is a safety feature designed to avoid unexpected startups, saving both the UPS module and the battery.

2.5.3.5 Switched DC Out

The Switched DC Out provides DC voltage to auxiliary equipment such as a radio transceiver or telephone modem. The Switched DC Output supplies an output voltage of 50 – 60 VDC.

Auxiliary devices connected to the Switched DC Output can reduce the available current for battery charging. Switched DC Out loading must be carefully limited to a long time average of 0.50 A. Higher current levels, up to 2.50 A, are allowed for short periods, although extended periods will limit the battery charging and may promote deep discharge of the battery.

The Switched DC Out may support one MDS-2310A radio or the equivalent using a DC-to-DC converter to power 12/24 V accessories. A 48/12 V DC-to-DC converter is available from ABB; contact your ABB sales office for this information.

The Switched DC Out is not fuse-protected against short circuits. If fuse protection is required, use the recommended external limiting resistor and fuse. Install in series with the Switched DC Output. The recommended parts are:

Resistor: 3 Ohm, 10%, 25 W wire wound—Ohmite L25J3R0 or equivalent Fuse: 2.5 A Fast Acting

2.5.3.6 Operation without a Battery

The UPS safely operates without a connected battery by using the capacitor assist module. The capacitor-assist module charges whenever the PCD is energized with AC. The capacitor-assist module allows for start-up, commissioning, testing and configuration of the recloser while the battery charges. Charging time for the capacitor assist module is approximately 30 seconds after
