摘要
针对谐波对煤矿井下电力系统污染严重、同时消耗大量的无功,需要对谐波和无功进行综合补偿的问题,采用了基于瞬时无功功率理论的谐波检测方法,并设计了一种由晶闸管控制电抗器(TCR)和混合型电力有源滤波器(HAPF)组成的谐波与无功综合补偿方案,实践证明既能有效补偿无功功率,又能有效滤除系统的谐波电流,改善了电压波动,提高了功率因数,改善了电力系统的电能质量,具有很好的推广价值。
Underground the coal mine power system seriously polluted by harmonic,also with a large amout of reactive power consumed,so it need for the comprehensive compensation to the harmonic and reactive power,this article applies a way of harmonic detection which is based on the theory of instantaneous reactive power,and designs a kind of harmonics and reactive power compensation scheme composed of the thyristor controlled reactor(TCR)and Hybrid Active Power Filter(HAPF)which can effectively filter harmonic currents in system,improve the voltage fluctuation,and increase the power factor,and impove power quality in power system,has good value of popularizing.
