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。
In order to solve the problem of harmonic pollution in power system, experts conducted a lot of research, tried various harmonic suppression and reactive power compensation measures, from the traditional LC filter to active power filter, a variety of harmonics Suppression technology out of the endless. In this paper, aiming at the actual situation of a power system, the problems of suppressing harmonics, compensating reactive power and eliminating harmonics caused by harmonics are studied and discussed, and the advantages and disadvantages of LC passive filter technology are analyzed. Based on this The system structure and working principle of hybrid active filter are introduced briefly. The actual operation results show that this hybrid active filter system has good filtering and compensation characteristics, basically solved the special problem of resonance.
