摘要
随着电力电子器件的大规模应用,其所具有的非线性特性给电力系统电能质量带来了诸多隐患,电力谐波就是其中之一。有源电力滤波器APF可以用于动态谐波抑制和无功补偿,具有显著地抑制和实时补偿效果。本文详细介绍了基于瞬时无功功率理论的谐波电流检测方法和控制策略,在MATLAB仿真环境下搭建并联有源电力滤波器模型,并对对该种滤波器的补偿能力进行仿真分析研究。
With the development of power electronic devices, nonlinear loads are widely used in power system, which bring about a series of problems influencing power quality. One of the problems is harmonic pollution. Active power filter can be used to suppress dynamic harmonies and compensate reactive power, and has the suppressive and compensative effect in real-time obviously. The paper introduces the harmonic detection and control strategies which base on instantaneous reactive power theory in detail, establishes shunt active power filter models by Matlab, and makes the simulation of harmonics compensation performance of the active power filter.
