The Parameter Design and Simulation Study of Injection Type Hybrid Active Power Filter

在配电网高压、大容量的谐波治理的背景下,提出了采用注入式混合有源电力滤波器的谐波治理方案。重点介绍了各个组成部分的设计方法。无源滤波器包括单调谐滤波器和注入滤波器,根据投资成本最小的方法设计。有源部分与基波谐振电路并联来减小有源部分容量;无源部分还可以提供很大的无功补偿容量,而且不影响有源部分的容量。仿真结果表明提出的混合有源滤波器的可行性。

Against the background of power distrition network, the scheme of an injection type hybrid filter system is presented. The paper mainly introduce the design methods of each composed part. Passive filter include single turning filter and injection filter, and design them based on the rule of the smallest cost. Active filter in perallel of fundamental series resonance circuits to reduce the power of active filter. Passive filters can supply high reactive power and this do not enlarge he capacitance Of active filter. Simulation results have verified the effectiveness of the proposed topology.
