10 3 Product Overview SMA Solar Technology AG 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. 10 PPC-BE-P7-en-13 Operating Manual

33 SMA Solar Technology AG 7 Operation 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". 1. Log into the user interface of the master as an installer (see Section , 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. 6. Adjust the setting for the mode of the slave operation in the Slave mode field: Mode of slave Description operation 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. 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. Operating Manual PPC-BE-P7-en-13 33

57 SMA Solar Technology AG 13 Appendix 13 Appendix 13.1 Structure of the System Network Two networks can be connected to the Power Plant Controller. This means that the output values can be transmitted to two PV system networks. The Power Plant Controller delivers the output values for the Cluster Controllers and the output values for the Sunny Centrals via separate LAN interfaces. To ensure the correct transmission of the output values, the following rules must be observed: If Sunny Centrals and Cluster Controllers are installed in the system, we recommend that they are organized in separate networks. If the Sunny Centrals and Cluster Controllers have to be operated in the same network, only one network can be used for transmission of output values. In this case, the time interval for transmitting output values is extended to at least the time interval determined for the Cluster Controller Principle of the Communication Network The Power Plant Controller communicates with the connected devices, with the network analyzer, the grid operator, and the SCADA system via Modbus protocol. The Modbus protocol is a communication protocol that is based on a client-server architecture. Figure 16: Principle of the communication network of the PV system with Power Plant Controller (example) 13.3 Scaling of the Analog Measuring Channels The Power Plant Controller can process both analog and digital measured values. If a network analyzer is used, the measured values are scaled automatically. Analog measured values are measured at the point of interconnection and converted by a transducer into values that the Power Plant Controller can process. Since the transducer can deliver values for active power, reactive power, voltage or frequency, the input values at the Power Plant Controller must be scaled. This is the only way that the Power Plant Controller is able to convert into technical values and continue processing the measured values from the values supplied by the transducer. For scaling, the possible range of the converted values and the range of the measured values must be entered in the user interface (see Section 7.9 "Selecting the Signal Source and Adjusting the Scaling of Measured Values", page 34). Operating Manual PPC-BE-P7-en-13 57

58 13 Appendix SMA Solar Technology AG The range between x0 and x1 refers to the converted values. This range is dependent on the measurement signal used and on the analog input to which the converted values are supplied. Measurement signal Analog input Measurement range of the analog signals Standard signal voltage Onboard 10 V 10 V Standard signal voltage Onboard 0 V 10 V Standard signal current Onboard 0 ma 20 ma Standard signal voltage Bus coupler 10 V 10 V Standard signal voltage Bus coupler 0 V 10 V Standard signal current Bus coupler 4 ma 20 ma Range of the converted values x0 = 8,192 x1 = 8,192 x0 = 0 x1 = 8,192 x0 = 0 x1 = 7,367 x0 = 32,768 x1 = 32,767 x0 = 0 x1 = 32,767 x0 = 0 x1 = 32,767 The range between y0 and y1 is the range into which the Power Plant Controller scales the converted values. This is equivalent to the measurement range. Within the measurement range is the range in which the valid measured values occur. The lower valid measured value corresponds to ymin, the upper valid measured value corresponds to ymax Example: Scaling of analog input values Analog voltage signals in the range from 10 V to +10 V are received at the analog input. The analog-to-digital converter of the Power Plant Controller uses this to generate a digital signal in the range of to The measured value processing in the Power Plant Controller calculates the reactive power value from this signal, and then limits it to the permitted range from 15 MVAr to +15 MVAr. Lower value for the range of valid measured values: ymin = 20 MVAr Lower signal value supplied by the transducer: x0 = Lower value of the measurement range: y0 = 15 MVAr Upper value for the range of valid measured values: ymax = +20 MVAr Upper signal value supplied by the transducer: x1 = Upper value of the measurement range: y1 = +15 MVAr 58 PPC-BE-P7-en-13 Operating Manual

59 SMA Solar Technology AG 13 Appendix 13.4 Output Value Specification Under Fault Conditions If transmission of the setpoints under fault conditions is not possible via Modbus protocol, the Power Plant Controller uses a substitution value or the last transmitted value. This is set for each specific system by SMA Service. Basically, three communication errors are possible: Error type The operator setpoints are not received by the Power Plant Controller. Actual values from the network analyzer are not received by the Power Plant Controller. Output value transmission to the devices is disturbed Control of the Power Plant Controller The output values are calculated with the last valid setpoint or with a substitution value. New output values cannot be calculated. The controller switches to manual operation and transmits the last valid output value or a substitution value. Depending on the parameterization, the connected devices work with the last valid output values received or with a substitution value. Parameterization Parameterization is carried out at the Power Plant Controller. Parameterization is carried out at the Power Plant Controller. Parameterization is carried out at the connected devices. Once the error in transmitting the setpoints of the Power Plant Controller via Modbus protocol has been eliminated, transmission of the output values calculated by the Power Plant Controller to the devices of the PV system automatically recommences Directive for Secure Passwords To protect the Power Plant Controller from unauthorized access, you must select a secure password.
