Fuzzy logic compensator of harmonic currents on shunt filter for photovoltaic generator

摘要

This paper, titled "fuzzy logic compensator of harmonic current on shunt filter for photovoltaic generator", presents a detailed solution for extraction harmonic current based on fuzzy_ logic and a comparative study with hysteresis method using THD figures. the fundamental of Instantaneous Reactive Power Algorithm is used for idenfication of reference harmonic current. The shunt active filter with the proposed method is modeled and simulated with MATLAB/Simulink. Then, simulation results are presented and interpreted. It is demonstrated that the fuzzy logic method improves the performance of the active power filter and decrease the THD value.
