Analysis and Investigation of the Inverter for Energy Transfer from Small Wind Power Plant to Common Grid

Abstract

The specific proportion of the parameters in the system: Small power source - Inverter with hysteresis controller - Grid causes unprofitable phenomena and difficulties with choice of the filter parameters, hysteresis band and other parameters assuring its good operation. The theoretical analysis of the phenomena in the circuits of the converter as well as its simulation and laboratory investigations were carried over. The system needs the great value of filter capacitance and the resistance for damping the low frequency resonance oscillation in the input circuit and the additional inductance for decreasing the current slope rate and switching frequency in the output circuit.
