| 摘 要： | 基于智能控制的新型配电网电能质量补偿器晶闸管投切滤波器TSF(ThyristorSwitchedFilters)是改善配电网系统电能质量的一种有效方法。首先从理论上分析了TSF补偿装置对抑制电压波动的基本原理,数学上推导出TSF投切最小过渡过程的角度,其次介绍智能控制在控制器中的应用,最后通过仿真和实验证明了TSF能够抑制电压跌落、电压波动及改善负荷的功率因数和减小谐波的有效性和可行性。

| Abstract: | A new power quality compensator of thyristor switched filters (TSF) based on intelligent control is an effective measurement to improve power quality of distribution network system. First, its principle to control voltage fluctuation is analysed theoretically, and the minimum angle of its switching in transition process is deduced in mathematics. Then, the application of intelligent control in controller is introduced. Finally, Through simulation and experiments, the effectiveness and feasibility of restraining voltage sag and voltage fluctuation, improving power quality and reducing harmonic by TSF are proved. |
