摘要
为了解决电力系统的谐波污染问题 ,专家们进行了大量的研究 ,尝试了各种谐波抑制和无功功率补偿措施 ,从传统的 LC滤波到有源电力滤波 ,各种各样的谐波抑制技术层出不断。文中针对某一电力系统的实情 ,就抑制谐波、补偿无功功率、消除谐波引起的谐振等问题进行了研究和探讨 ,对 LC无源滤技术的优劣作了分析 ,在此基础上对混合型有源滤波器的系统构成及工作原理作了简单介绍。实际运行结果表明 ,这套混合型有源滤波系统具有良好的滤波和补偿特性 ,基本上解决了谐振这一特殊问题。
To solve the problem of harmonic pollution in power system,experts have made a large number of research and attempted various of harmonic restraining and VAR offsetting measures.From traditional LC filtering to powered electricity filtering,all kinds of harmonic restraining technology emerges in an endless stream.The paper analyses the good and bad of non powered filtering technology.In accordance with the actual situation of some power system,the paper studies and probes into the problem of harmonic restraining and VAR offsetting and resonance,simply introduces the system forming and work principals of the powered filter.Actual work results indicates that the sort of mixed powered filtering system has good filtering and offsetting specific property and primarily solves special problem of resonance.
