摘要
提出了一种综合型电力滤波系统，它由无源滤波器和小容量的有源滤波器串联构成，与被补偿的谐波负载并联连接。其中，有源滤波器可以等效为谐波阻抗，它使无源滤波器和有源滤波器对各次谐波的串联阻抗为零，以有效地提高无源滤波器的滤波效果，并能有效地抑制系统阻抗和无源滤波器之间所产生的串并联谐振。由于有源滤波器的容量非常小，适于对大容量的谐波负载进行补偿，具有很好的实用性和经济性。仿真分析对该方法的正确性和可行性进行了证明。
This paper presents a combined power filter system. It consists of a small rated active filter and a passive filter which are connected in series with each other and installed in parallel with the harmonic load. The active filter is equivalent to harmonic impedance and makes the series harmonic impedance of the passive filter and the active filter to be zero. In this way, the filtering characteristics of the passive filter can be improved. Parallel and series resonance between the source and the passive filter also can be dumped effectively. The small required rating of the active unit makes it more suitable to the compensation for large scale harmonic loads. This make it more practical and economical. Simulation results verify the feasibility of this system.
