摘要
大量的电力电子设备应用于各个领域,带来了节能、便于控制等好处,但同时也带来了谐波污染问题。谐波污染不仅对其他设备的稳定运行和电网的安全性造成了威胁,而且干扰了用于无功补偿的并联电力电容,使其寿命降低、投切失灵。在分析去谐补偿参数的基础上,提出了采用有源滤波器和无功补偿单元作为解决该类电能质量问题的整体技术方案。
Many electronic equipments were applied on various fields.It brought not only the advantages of energy saving and easily control,but also problems of harmonic pollution.Not only the safety of power grid and the stable operation of other equipments were threatened by harmonic pollution,but also the power capacitor paralleled for reactive compensation was also disturbed,consequently resulting in the capacitor life reduction and switching fault.Based on the analysis of detuned compensation parameters,the combination solution of PQF active filter and RCR was introduced.
