摘要

配电系统中由于负荷的不确定性

低压线路往往在高峰和低谷负荷时出现无功不足或无功过补偿的情况

从而导致线损增加。文章提出了一种无功补偿的模糊控制方法

考虑一天内当前负荷和未来2 h负荷的变化趋势

并把它们用时间信息来表示。模糊控制器的输入为时间信息和功率因数

而输出信号用来控制并联电容器组的投切。通过Labview实现该模糊控制器并将其应用于某低压配电区

分析结果说明该方法可以减少投切的次数并获得较好的补偿效果。

Abstract

In the distribution network

due to uncertainty of load

low voltage line often occur such case as insufficient reactive power compensation or over-compensation at Min and Max load

leading line loss increased.In this paper

a kind of fuzzy control method for reactive power compensation is proposed

which considers variation load at present and in 2 hours within one day and expresses it with time information.The input of fuzzy controller are time information and power factor

while the signal is used to control switching of shunt capacitor bank.The fuzzy controlled is achieved and used at certain low voltage distribution area through Labview.It is shown by the analysis result that the method can reduce switching numbers and get better compensation result.
