中山地区电网电压无功优化系统研究

Study on Optimization System for Voltage and Reactive Power in Zhongshan District Power Network

文章分析了广东省中山地区电网电压自动控制装置运行现状,根据中山地区电网结构特点,提出分级控制方案,计了一套基于全局电网范围的电压无功优化系统(AVC),详细介绍了该系统的结构、控制模式、控制流程和运行情况。

The status quo of control of voltage and reactive power of substations and construction situation of optimization system for voltage and reactive power in Zhongshan district power network are introduced in this paper.This paper is specified in aiming at the existing deficiency of adopting the way to adjust the power grid scattered in Zhongshan district,proposed the voltage control based on ＂bus hub＂ and ＂control the region＂,which proposal of voltage controlled by grades had been put into effect in several other foreign countries and achieved satisfactory results.This kind of system is remarkable for its capability,which can reduce the frequency of regulating the equipment and extend the durability of it as well as taken effective automatic control of voltage power and reactive power.
