3 Product Overview
3.1 System Overview
The Power Plant Controller assumes the park management function in large PV systems. The PV system can combine both central inverters and decentralized string inverters, which are monitored and controlled by Cluster Controllers.
Figure 1: Principle of signal transfer in a PV system with Power Plant Controller
In the Power Plant Controller, the setpoints for grid management services are received and compared with the values measured at the point of interconnection. Based on this comparison, the Power Plant Controller calculates the required output values and transmits these values to the central inverters and the Cluster Controllers or the Inverter Manager. The Power Plant Controller can receive setpoints digitally, analog, and via Modbus protocol. The setpoints are transmitted by the grid operator or by a higher-level SCADA system via Modbus protocol.
The measured values that the Power Plant Controller receives are measured at the point of interconnection, processed by a network analyzer, and transmitted to the Power Plant Controller as analog values or via Modbus protocol.
Transmission of the output values from the Power Plant Controller to central inverters, Cluster Controllers and the Inverter Manager takes place via Modbus protocol.

7.6.4 Adjusting the Configuration of the Network Analyzers
At the point of interconnection, the current values for active power, reactive power, voltage and frequency are measured. The measured values are captured in up to three network analyzers. For each variable, a network analyzer can be selected as the source for the default value. A second network analyzer independent of the first network analyzer can be selected as the source for the redundant second measured value. If one of the default values fails, the redundant second measured value will be used in its place.
The measured values are either queried by the Power Plant Controller via Modbus using a network analyzer or submitted to the Power Plant Controller as analog input signals.
In order to ensure the correct processing of the measured values, the network analyzer used must be configured. After commissioning the Power Plant Controller, you can still change the IP address of the network analyzer, adjust its device type and assign it a unique name.

7.6.5 Adjusting the Configuration of the Power Plant Controller Slaves
Using Power Plant Controllers, you can monitor a PV power plant with up to 1,000 central inverters. The master/slave concept of the Power Plant Controllers enables all 1,000 inverters to be controlled uniformly and simultaneously. The Power Plant Controller master transmits the output values for the active and reactive power control to the
Power Plant Controller slaves and to all inverters connected to the master. A Power Plant Controller master can control up to ten Power Plant Controller slaves.
In the Power Plant Controller master, the IP addresses of the Power Plant Controller slaves and the mode of the slave operation must be set. If necessary, the Power Plant Controller slaves can be divided into different control groups. It can also be set whether the Power Plant Controller master must pass the disconnect command to the slave or not. The settings for the fast stop command can only be made using the user level "service technician".
Procedure:
1. Log into the user interface of the master as an installer (see Section 11.3.1, page 54). 2. Go to PPC > Grid system services > Device table PPC slave.
3. Enter the number of slaves for this Power Plant Controller master in the Number PPC slave field. 4. Enter the name of the slave in the Device name field.
5. Enter the IP address of the slave in the fields IP1 to IP4.

7. If necessary, enter the number of the group that the slave belongs to in the Control group field.
7.7 Adjusting the Settings of the Modbus Server
The communication between the Power Plant Controller and the grid operator or a higher-level SCADA system takes place via Modbus protocol. You can disable communication with the grid operator via Modbus protocol and change the IP address of the Modbus server. You can configure whether setpoint changes are only to be accepted if the change counter register is set simultaneously in the Modbus protocol.
If the Modbus Client is inactive, the connection will automatically be cut off after 60 seconds, even if the setting Setpoint monitoring is activated. The time can be adjusted from 1 s to 60 s in the field Setpoint monitoring time.
Mode of slave
operation Description
1 The active power setpoints are processed by the controller of the master and transmitted as output values to the slave. The slave does not control but transmits the output values to the inverters.
or
Cascade control: The active power output values of the master are processed by the slave controller as setpoints and sent to the inverters. For this mode of slave operation, the slave must receive the actual values from an additional network analyzer. This network analyzer must record the values of the part of the PV power plant that is to be controlled. For cascade control, therefore, an additional network analyzer is required for each slave.
The reactive power setpoints are processed by the slave's own controller.
2 The reactive power setpoints are processed by the controller of the master and transmitted as output values to the slave. The slave does not control but transmits the output values to the inverters.
The active power setpoints are processed by the slave's own controller.
3 The active and reactive power setpoints are processed by the controller of the master and transmitted as output values to the slave. The slave does not control but transmits the output values to the inverters.
Procedure:
1. Log into the user interface as an installer (see Section 11.3.1, page 54). 2. Go to PPC > Settings > Modbus server.
3. To adjust the profile of the Modbus server, select the desired entry in the drop-down list Modbus server profile. 4. To enable or to disable the Modbus server, select the option Yes or No in the drop-down list Active.

7.9 Selecting the Signal Source and Adjusting the Scaling of Measured
Values
The measured values of the PV system that are used to calculate the output values can be transmitted via various channels to the Power Plant Controller. If the signal transmission changes after commissioning the Power Plant Controller, it can be adjusted. The settings for the individual measured values of active power, reactive power, voltage, and frequency can be made separately.
If an error occurs during transmission of the measured values via Modbus protocol, the last calculated output values can be used (see Section 13.4 "Output Value Specification Under Fault Conditions", page 59), or you can use substitution
SMA Solar Technology AG 7 Operation
Measured values submitted to the Power Plant Controller as analog signals will be converted to digital values in the Power Plant Controller. The measured values in technical units must be calculated from the digital signals. The signals submitted by the transducer to the Power Plant Controller must be scaled (see Section 13.3, page 57). Scaling of the measured data is only possible if under PPC > Settings > Modbus server or under PPC > Grid system services > Device table Power Analyzers > Power Analyzer 1 the entry Yes has been selected in the drop-down list Customized scaling, or if analog signals are used.
Procedure:
1. Log into the user interface (see Section 11.3.1, page 54).
2. Go to PPC > Grid system services > Input signals > Measurement values.
3. To assign the record from which the active power setpoint is to be calculated, select the button [Active power] under Measured values 1 (default) or Measured values 2 (redundant) in the right-hand menu bar.
4. If an error has occurred and the Power Plant Controller needs to supply substitution values, select the entry Yes in the drop-down list Substitution value and enter the required substitution value.
5. To switch the device or the input supplying the measured data, select the appropriate entry in the drop-down list Signal source.
– Modbus server: The measured values are transmitted via Modbus protocol from the grid operator to the Power Plant Controller.
– Modbus device: The measured values are transmitted via Modbus protocol from the network analyzer to the Power Plant Controller.
– Onboard: The cables supplying the analog measured values are connected directly to the analog inputs of the Power Plant Controller.
– Bus coupler: The cables supplying the analog measured values are connected to a bus terminal of the Power Plant Controller.
6. If you have selected the setting Modbus device in the drop-down list Signal source, you will now need to define the network analyzer at which the signal is present.
7. If you have selected the setting Onboard or Bus coupler in the drop-down list Signal source, you will now need to define the input at which the signal is present. To do this, select the corresponding entry in the drop-down list Hardware channel.
8. If the measured data are not supplied by a network analyzer or the network analyzer does not have an averaging function, averaging of the data can be configured here. To do this, enter the desired number of values in the field Averaging x values. Entries are possible between 1 (no averaging) and 10 (averaging from 10 measured values).
9. If the measured data are supplied as analog signals, adjust the scaling of the measured values: – in the field yMin., enter the lowest value in the range of valid measured values
– in the field yMax., enter the highest value in the range of valid measured values – in the field x0, enter the lowest signal value supplied by the transducer
– in the field x1, enter the highest signal value supplied by the transducer – in the field y0, enter the lowest value in the measurement range – in the field y1, enter the highest value in the measurement range
☑ When measured values are received without errors, No is displayed in the field Error. ✖ Yes is displayed in the Error field?
No measured values are being received by the Power Plant Controller or the values received are outside the permitted range. An error is displayed and the substitution value is used.
10. To configure the settings for further measured values, repeat the settings from Step 3 for each setpoint.
11. To make settings for the measured values of the sensors, go to PPC > Grid system services > Input signals > Measurements common.
