芜湖电网自动电压控制(AVC)系统的功能与应用

Function and application of AVC of Wuhu power grid

主要介绍芜湖电网自动电压控制(AVC)系统的基本功能和在实际中的应用情况。芜湖电网通过AVC系统的运行,在调度自动化系统的主站端对分站的母线电压和关口无功进行监控,实现了无功优化、减低网损,保证了母线电压合格,表明在芜湖电网实施该系统是有效可行的,并取得了一定的经济效益和社会效益,实现了该电网从经验型调度向分析型调度的转变。AVC系统已成为电网安全、优质和经济运行的重要手段。

This paper introduces the basic functions and practical application conditions of the Wuhu power grid AVC system. The main station of the dispatching automatic system can control the bus voltage of the branch station and key reactive power and realize optimal reactive power and lower the line loss, and ensure qualified bus voltage due to the operation of the AVC system.. The operation of AVC system demonstrates that AVC system is feasible and economical and the system has become the main means of safe and economic operation of the grid and turned the empirical dispatching into analytical dispatching.
