This paper proposes a new starting method of the harmonic current compensator using the hybrid active filter for wind power generation systems. In the proposed method, an active filter of the hybrid power filter behaves a resistor and reactive power compensator to suppress the source currents oscillation and leading currents under the starting conditon. The basic principle of the proposed starting method is discussed, and then confirmed by digital computer simulation using PSCAD/EMTDC. Simulation results demonstrate that the proposed starting method can overcome the inrush and phase-leading currents, building up the dc capacitor voltage of the active filter.
