电网无功补偿模糊控制方法的仿真与实现

Simulation and Implementation of Fuzzy Control in Reactive Power Compensation

电网中的无功补偿采用自动投切装置,在投切控制上,研究了以电压和无功功率两个量进行控制。运用模糊控制的方法,将电压和无功功率的取值范围划分为若干区域,确定各区域的隶属度。用MATLAB软件进行模拟仿真,符合无功控制的基本原则和系统的实际要求,弥补了以前的单一因素控制的不精确性,消除了不必要的往复投切。结果表明,模糊推理控制电容器的投切是一种最佳设计方法,获得了理想的控制效果。

Auto-switching devices were used in reactive power compensation for switching control. The voltage and reactive power were studied. With the use of fuzzy control, the range of voltage and reactive power were divided into several regions to deter- mine the membership of each region. Using MATLAB simulation fit the basic principles and the actual system requirements in reactive control. It increased the control accuracy, and eliminated unnecessary repeated switching. The result showed that fuzzy inference control of the capacitor switching is the best design, and gets an ideal control.
