Topology and Functions of Large-Scale PV Power Station Monitoring and Control System

摘要

According to the development status of large-scale PV power station, this paper expatiates the topology and functions of the monitoring and control system of large-scale PV power station, The system consists of monitoring center, fiber optic ring network and control subnet, and the main functions are SADA (supervisory control and data acquisition), AG (automatic generation control), AVC (automatic voltage control), system state assessment, equipment maintenance, and power generation benefit analysis. The system is flexible and reliable, and will promote the efficiency of operation and maintenance of large-scale PV power station.
