摘要
为了补偿较大的无功功率,降低传统的有源电力滤波器(active power filter,APF)的容量,提出将有源电力滤波器与晶闸管投切电容器(thyristor switched capacitor,TSC)相结合构成混合滤波系统。该系统充分利用APF动态补偿性能好,TSC容量大的特点,有效地消除电网中的谐波电流和提高功率因数。通过仿真研究,结果验证了系统的有效性和可行性,并且表明该系统具备较好的动态响应性能和稳定性。
In order to compensate more reactive power and lower the power level of the active power filter （APF）, a hybrid filter system based on a combination of the APF and the thyristor switched capacitor （TSC） was presented. This system combines the good dynamic compensation performance of the APF and higher power level of the TSC. It can eliminate harmonics and compensate the power factor effectively in power distribution systems. Simulations show that this topology has rapidly dynamic response and stability. And the feasibility and validity of this system has been proved.
