摘要

以无功控制理论为基础

分析了在电力系统中电压和无功之间的关系

提出了用装设无功控制装置的办法来实现在额定电压下的系统无功功率平衡。为了使无功控制装置具有快速、准确的特点

装置采用了以常见的可编程计算机控制器（PLC）为控制器

用晶闸管做执行元件投切电容器

采用闭环控制系统

使装置在运行时能充分发挥PLC用于工业控制的优越性和晶闸管快速通断的特点

为无功补偿控制装置的开发提出了一种新的开发思路。

Abstract

It is

based on the reactive power control theoretical and analysed relation between the voltage and the reactive power in the power system

proposed in this paper to achieve reactive power balance of the system by installing reactive power controlling device.For keeping the reactive control device having features of fast and accurate

the PLC is used as controller and thyristor as implementing element to switch the capacitor.The closed-loop control system is used and the superiority of PLC’s industrial control application and thyristor’s fast interruption and conduction characteristics are fully utilized in the operation.And a kind of new idea for the development of reactive power compensation control device is proposed.
