Power plant controller for photovoltaic plants at the point of interconnection
PPC (Power Plant Controller) acts as the central controller of a photovoltaic power plant and manages inverter concentrators and inverters of the power park module PPM. It calculates and distributes setpoints so that active and reactive power parameters at the point of interconnection POI comply with network codes. The controller is installed at PV plants and hybrid RES facilities connected to MV and HV networks.
- Purpose

Description
The main task of the controller is to coordinate PPM devices and control power parameters at the POI. PPC receives setpoints, calculates the reference for each actuating device and sends it to inverter concentrators, inverters and other plant equipment. One controller handles a large number of inverter concentrators and inverters within the PPM at the same time. Regulation is subordinated to the requirements of the NC RfG network code and other documents defining the operation of the facility. Functions include remote cessation of active power generation, remote reduction of generation with operation in limiting mode, a power guard function and regulation by the static Q(U) characteristic.
The controller is built on several hardware platforms. On the SO-52v11 controller, the central processor PJC-865-C2 or PJC-865-42/-A2, the MP01 cassette and the MZA-410 power supply are used, and the 6U cassette comes in MP01 or MP03 types. The SO-52v21 platform is built on the mCU-03-10 processor with a 16N cassette for 16 modules and a 230 V supply, and SO-52v12 on the pCU-02-48 processor with a 16N cassette. One more variant is assembled on the integrated MSG-701 controller. The controller is complemented by input-output modules for connecting external devices.
Data is exchanged with inverters of different manufacturers and with higher-level systems over standard protocols IEC 60870-5-104/101/103, IEC 61850, DNP3.0 and MODBUS RTU/TCP. Physical interfaces include Ethernet 100 TX/FX on SO-52v11 and 100/1000 TX/FX on SO-52v21 in multimode or single-mode versions, as well as RS-232 and RS-485. Protection of communication, stored data and configuration is built on IPSec VPN, TLS, OCSP, SCEP, SYSLOG, RADIUS and role-based RBAC access.
The logic function module implements additional customer requirements by means of programmable logic, that is, any logic functions and executive algorithms. The device is designed for harsh conditions with heavy dust, humidity and electromagnetic interference. The SO-52v11 and SO-52v21 controllers in the PPC version are manufactured in accordance with directives 2014/30/EU and 2014/35/EU. For the SO-52v11/v12/v21-PPC and SO-54SR-901-PPC versions, the company has published brochures and an annex to the conformity certificate of the controller.

Questions and answers
Which active and reactive power control functions does PPC perform?
The controller performs remote cessation and reduction of active power generation, the power guard function and regulation by the Q(U) characteristic. Setpoints are calculated for the point of interconnection POI in accordance with NC RfG.
Which communication protocols does the controller support?
PPC works over IEC 60870-5-104/101/103, IEC 61850, DNP3.0 and MODBUS RTU/TCP. This is how it exchanges data with inverters of different manufacturers and with higher-level systems.
On which hardware platforms is PPC supplied?
The controller is built on SO-52v11, SO-52v21 and SO-52v12 controllers or on the integrated MSG-701 controller. An SO-54SR-901-PPC version is also available.
