چکیده انگلیسی

Active Power Filters (APFs) are widely used in power systems that require best power quality. This is because the APFs have the ability to bring the system having unity power factor, to balance the system and to eliminate the harmonic phase currents. However, the rating of an APF depends to the corresponding load where the APF should be able to provide the compensating the required power. If more loads are to be installed on the system, it is possible that the rating of the existing APF is no longer sufficient. Thus, the protection mechanism will work and release the APF from the network, and the APF system will no longer contribute to the system. Therefore, it is necessary to find an algorithm that is able to work under overload conditions without damaging the APF. In this paper 2 algorithms for APF used for overload conditions are proposed. These algorithms are developed based on PQ0 theory for 3 phase 4 wire system. APF will continue to contribute in power compensation although the load exceeds the capabilities of the APF without the need to shutdown the APF. Simulation results are shown to verify the performance of the proposed method.
