A starting method of the harmonic current compensator using a hybrid active filter for wind power generation systems with soft starters

This paper proposes a new starting method of a harmonic current compensator using a 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 inrush current and leading currents for the passive filter under the starting condition. 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 leading currents for the passive filter, building up the dc capacitor voltage of the active filter.
