Comparative Study on Control Strategies of Parallel Hybrid Active Power Filters

Abstract:

In this paper, a comparative study on control strategies of parallel hybrid active power filters (PHAPF) is presented. A universal electric model of three different PHAPF is proposed. The principle for the harmonic current elimination of PHAPF when different control strategies are adopted is analyzed. As the performance of the PHAPF will be influenced by the fluctuation of the power system parameters, a comparative study of the influences when different control strategies are adopted is carried out. The conclusions can help in the choice of an optimal basic control strategy, and guarantee the secure operation of the PHAPF system. Experiments have been carried out to verify the validity of the theoretical analysis in this paper.
