The Power Quality Compensation Strategy for Power Distribution System Based on Hybrid Parallel Active Power Filters

In this paper, the main aim is to confront the performance of shunt active power filter (SAPF) and the shunt hybrid active power filter (SHAPF) to achieve flexibility and reliability of the filter devices. Both of the two devices used the classical proportional-integral controller for pulse generation to trigger the inventers MOSFET’s. In the adopted hybrid active filter there is a passive power filter with high power rating to filter the low order harmonies and one active filter with low power rating to filter the other high order harmonies. In order to investigate the effectiveness of (SHAPF), the studies have been accomplished using simulation with the MATLAB-SIMULINK. The results show That (SHAPF) is more effective than (SAPF), and has lower cost.
