ABCS-2000 series new energy grid connected control system

Overview

This system is suitable for box type step-up transformers of new energy stations (wind or photovoltaic power generation) in indirect grounding systems or low resistance grounding systems of 35KV and below. It has intelligent protection, measurement and control, online monitoring of power quality, and communication control functions. This system has protection functions (three-level composite voltage blocking overcurrent protection, two-level negative current protection, two-level zero sequence overcurrent protection, low voltage protection, overvoltage protection, non electricity protection), measurement and control, power quality monitoring, power metering, ring network switching, etc., and is suitable for panel installation. The system establishes communication between the dispatch master station and the renewable energy master station (wind or photovoltaic station). It uploads remote communication, telemetry, electricity and power quality data to the dispatch master station, and receives remote control and dispatch commands from the master station. At the same time, it forwards remote control and start/stop commands to the inverter controller/wind turbine in the station, and receives relevant remote signals sent by the photovoltaic inverter controller/wind turbine. According to the actual communication conditions, the communication between the main station and the grid connected control system of the distributed photovoltaic power station can be achieved through optical communication, using IEC60870-5-104 or other communication protocols.
