有源电力滤波器双环软启动实用控制策略分析

Practical control strategy analysis on dual-loop soft-startup for active power filter

本文从配网系统谐波研究的实际问题出发,以有源电力滤波器的关键技术为研究对象,对双环软启动控制策略的工作过程进行研究和分析,揭示出有源电力滤波器各控制参数间的关联和制约关系,同时模拟程序执行的实际情形建模和仿真修正了参数,以双CPU控制为核心设计制作了一套应用于低压配网380V,容量为100kVA的并联电压型有源电力滤波器装置,并验证了其策略在应用中的可行性,将有助于进一步实际研发。

The paper is based on the practical problems of the harmonics in distribution network.The key tech-niques of Active Power Filter have been analyzed in this paper,especially the dual-loop soft-startup control strategy is studied and analyzed to reveal the main control parameters of APF.A 380V 100kVA shunt voltage-type APF ex-periment prototype using dual-CPU is implemented.Many experiments are done on the experimental equipment of APF and satisfactory result is drawn,which can contribute to actual research development and production.
