15. STATUS MONITORING & CONTROL 15. STATUS MONITORING & CONTROL
15.1 SWITHCH CONTROL 15.1 SWITHCH CONTROL
Recloser can be controlled from remote or local operator place. Operator place can be changed only at local front panel. ‘REMOTE CONTROL’ push button is to select the operator place. Operator place is toggled between local and remote by pushing button. LED is lit if remote position is selected. FTU-R200 begins with remote position at power-up. Control is allowed only at the position selected.
Local switch control requires two-step operation. It’s for security of operation. ‘SELECT’ button should be pushed before ‘CLOSE’ or ‘OPEN’. SELECT LED is lit if SELECT operation is valid. SELECT can be canceled by pushing SELECT button again or automatically after SBO timeout without operation. CLOSE or OPEN operation is valid while this LED is lit. Pushing CLOSE or OPEN button outputs switch control signal with fixed time pulse which is configurable. Switch status change input which is auxiliary contacts of switch stops continuing to output pulse. There are some interlock conditions to inhibit FTU from outputting pulse signal.
Gas low, Switch handle lock, same status of switch auxiliary contacts ‘a’, ‘b’ are those. Close or open pulse width shall be set longer than switch operating time.
Remote switch control is possible by using SCADA protocol DNP3.0 or IEC60870-5-101, IEC60870-5-104 FTU-R200 supports SBO (Select Before Operate) or Direct operate. If the operator place is set to ‘Local’, remote control commands are refused. Pulse width of remote control command shorter than setting will be overridden by local configuration
15.2 SWITCH STATUS MONITORING 15.2 SWITCH STATUS MONITORING
FTU monitors switch open/close, gas and lock status through auxiliary contacts. FTU scans these contacts input every 5 milliseconds. Switch open/close status is determined by double binary input, normally open and closed contacts. Changes of all input status are saved as events with time tag in history buffer. For each contact input, on-delay time can be applied. It’s adjustable within 10~500ms by 5ms step.
15.3 BATTERY MONITORING 15.3 BATTERY MONITORING
FTU monitors external Lead-acid battery through the control unit, which are mounted on inner back-side of control box. Battery voltage is supervised continuously during external AC supply loss. If over-discharge condition occurred, the control unit sends alarm signal to RTU and disconnect battery in order
ISO 9001 certified Jin Kwang E & C Corp.
to protect battery cell damage after 1-minute delay. The delay enables RTU to send alarm state to remote station via communication. Also while AC supply is applied, battery test control activates this function with connecting dummy battery load during test pulse, which is configurable. The test control command can be ordered at local or remote.
16. MEASUREMENT 16. MEASUREMENT
16.1 BASIC ELECTRIC QUANTITIES 16.1 BASIC ELECTRIC QUANTITIES
FTU has 3-phase currents and 6 voltages input. DSP digitizes these signals and calculates various electric quantities. These are basically based on fundamental frequency components. DSP use FFT (Fast Fourier Transform) algorithm to get the components. Also DSP calculates true RMS of 3-phase currents and voltages which include system frequency components and 2nd~31th harmonics. Actually harmonic components over than 31th are attenuated by analog filters. Electric quantities calculated are listed in the following.
RMS, Phase Angle, True RMS
l
l Apparent Power A-Phase, B-Phase, C-Phase, 3-Phase Total, l
l Active Power A-Phase, B-Phase, C-Phase, 3-Phase Total, l
l Reactive Power A-Phase, B-Phase, C-Phase, 3-Phase Total, l
l Power Factor A-Phase, B-Phase, C-Phase, 3-Phase Total, l
l Va-Vr Phase Angle Difference
l
l Current, Voltage Unbalance
l
l Frequency, Temporature
In the above items listed, active power, reactive power values are signed integer. Sign represents power flow or if loads are inductive or capacitive. Also power factor has lead/lag state value separately.
Currents and voltages have phase angles, which are relative phase angles compared to the reference Va. These angles are useful to monitor the phase sequence and imbalance of distribution line.
16.2 SEQUENCE COMPONENTS 16.2 SEQUENCE COMPONENTS
FTU provides the sequence components of 3-phase currents and voltages. They are positive sequence current (I1) and voltage (V1), negative sequence current (I2) and voltage (V2), and zero sequence voltage
ISO 9001 certified Jin Kwang E & C Corp.
16.3 HARMONICS 16.3 HARMONICS
FTU extracts harmonic components from 3-phase current and voltage signals by using FFT (Fast Fourier Transform). It provides 2nd to 31st harmonic magnitudes and THDs (Total Harmonic Distortion) for each phase. THD is the total harmonic percentage to the fundamental frequency component. FTU also calculates and provides 3-phase THD. These values may be used to monitor the power quality of distribution line.
16.4 ENERGY 16.4 ENERGY
FTU provides active energy, reactive energy for each phase or 3-phase total. Also import, export energy are accumulated on separate register. Units of energy are kWh, kVarh, which represent primary distribution line energy flow. The values are represented by 16-bit rollovers kWh, kVarh counters which are available at remote or local. Power calculation for energy is based on the fundamental frequency component. It’s not for billing purpose, but for load management. Proper energy accumulation needs that SCADA read energy counter with reset from FTU and accumulate it on SCADA’s local register by periods shorter than the expected rollover time of the counter.
[Four-quadrant power flow directions ]
16.5 DEMAND CURRENTS AND POWER 16.5 DEMAND CURRENTS AND POWER
FTU calculates and stores average of currents and active, reactive powers during the demand interval, which is configurable as 5, 10, or 15 minutes. The buffer has 1023 demands. Also FTU stores daily peak demand up to 1023.

Each line in the CSV file corresponds to a row in the table. Within a line, fields are seperated by commas, each field belonging to one table column.
