摘要
本文介绍了并联型有源电力滤波器的工作原理和基于瞬时无功功率理论的谐波和无功电流检测方法,用Matlab Simulink建立了带典型负载的电力有源滤波器的仿真模型,模拟实际系统,用于检验其策略和参数在实际条件下的工作情况。仿真模型的结果表明:基于瞬时无功功率理论的有源滤波器,可以很好的起到动态抑制电网谐波和补偿无功的作用。
The principle of shunt active power filter and the harmonic and reactive current detection applying instantaneous reactive power theory is introduced in this paper. A matlab simulation model about active power filter is built for typical harmonic source. It is used to verify the going of the strategy and the parameters under the practical condition. The simulation results reveal that the active power filter based on instantaneous reactive power theory can effectively restrain harmonic current and compensate reactive current dynamically.
