变电站电压无功自动控制装置的研制分析

Development and Analysis of Substation Voltage and Reactive Power Automatic Control Device

随着现代电网电力系统的日渐扩大,人们对电网可靠性以及电能质量要求越来越高,而电压稳定性也成为衡量电能质量的重要标准。文中对电压无功控制原理以及无功自动控制目标进行了介绍,并从参数配置、断路器选择、控制装置主体部分的研制、模拟量和开关量数据控制、单片机软件控制设计等方面,论述了变电站电压无功自动控制装置的研制分析,并提出电压震荡的具体解决办法。

With the increasing expansion of modern power grid,people are demanding higher and higher reliability and power quality,and voltage stability has become an important standard to measure power quality.This paper introduces the principle of voltage and reactive power control and the goal of reactive power automatic control.It also discusses the automatic control of voltage and reactive power in substation from five aspects:parameter configuration,selection of circuit breaker,development of main part of control device,analog and switching data control,software control design of single chip microcomputer.The development of the device is analyzed,and specific solutions to voltage oscillation are proposed.
