A series hybrid power filter to compensate harmonic currents and voltages

In this paper a series hybrid power filter (SHPF) to compensate harmonic currents and voltages at PCC is proposed. The SHPF consists of a small-rated series active power filter (SRSAPF) and a series tuned passive filter (STPF). This combination is suitable for compensating voltage type harmonics-producing load. The SHPF uses the synchronous rotating frame method, which detects both source current and load voltage harmonics. Simulation results using Power System Blockset Toolbox PSB of Matlab show the performance of the series hybrid power filter, and its capability to compensate for voltage type harmonics-producing load.
