摘要

AVC系统采用电压期望值作为连续可调无功源的控制指令值

由于各类连续可调无功源的调节速度存在差异

导致出现"抢无功"的现象

不利于电网安全经济优质运行。为解决这一问题

本文提出了一种AVC控制指令选择方法

即选择灵敏度高、调节速度快的连续可调无功源下发电压期望值作为控制指令

其余下发无功出力期望值作为控制指令。该方法与现有AVC系统结合

形成一套AVC控制指令选择系统

可有效解决"抢无功"问题

保证电网安全经济优质运行。

Abstract

The existing AVC system uses the expected voltage value as the control command value of the continuous adjustable reactive power source.However

the phenomenon of "grabbing reactive power"

which is caused by the difference in the adjustment speeds of various continuous adjustable reactive power sources

is not conductive to safe

economical and highquality operation of the power grid.To solve this problem

a method of selecting AVC control command is proposed

in which the expected voltage value as control command is delivered to the the continuous adjustable voltage source with high sensitivity and fast adjustment speed and the expected reactive power is delivered to the rest.This method

combined with the existing AVC system

forms an AVC control command selection system to effectively solve the problem of"grabbing reactive power"and ensure safe

economical and high-quality operation of the power grid.
