Power distribution network automation system PCS-9700

PCS-9700 is a state-of-the-art automation system for substations, power plants and various industries. PCS-9700 is equipped with diverse advanced technologies and patents. It can be incorporated into various substations, from distribution level to Extra High Voltage (EHV) level. It integrates the applications of protection, control, Ethernet, IT and communication technologies based on international standards. Furthermore, PCS-9700 is fully compatible with the IEC61850 standard. The system adopts the layered distributed architecture with a bay-oriented and object-oriented structure, which is more reliable, extensible and easy to maintain. NR also provides solutions that allow retrofit from the conventional substation to digital substation. Real-time data acquisition and processing PCS-9705 Bay Control Unit (abbreviated as BCU) is applied to perform real-time data acquisition and processing. Control operation, synchronism-check and interlocking PCS-9705 BCU carries out control operations, synchronism-check and interlocking functions for Circuit Breaker (CB), Disconnector Switch (DS), Earthing Switch (ES), transformer tap changer and etc. Communication with control center PCS-9799 Station Manager works as a station communication manager, which collects, stores and maps signals of relays, measurement units, control units and other IEDs in the substation to higher-level systems such as control center (CC) and distributed control system (DCS). PCS-9799 supports several protocols, such as IEC 61850, IEC 60870-5-101/104, IEC 60870-5-103, Modbus and DNP3.0. Clock synchronization
