摘要
为了降低有源电力滤波器(APF)的容量,同时有效消除电网谐波电流并提高功率因数,提出了APF加晶闸管投切电容器(TSC)的混合补偿系统。分析了该混合补偿系统的主电路结构和工作原理。通过对比试验研究证明,该混合补偿系统不仅可显著提高电网功率因数,而且能有效消除非线性负载产生的谐波电流,具有较好的实用价值。
In order to reduce the power level of the active power filter （APF） and eliminate harmonics and improve power factor, a hybrid compensation system based on a combination of the APF and the thyristor switched capacitor （TSC） was presented. The main circuit structure and the working principle were analyzed. The comparative experimental resuhs indicate that the hybrid compensation system can not only significantly improve the power factor, but also eleminate the harmonics currents arised from nonlinear load effectively. The proposed system has satisfactory practical application value.
