Abstract

This paper proposes a detailed control strategy for multiple parallel connected converter units integrated with wind turbine driving PMSG. A model of multiple rectifiers in parallel with common dc link and zero sequence current dynamics are derived and analyzed. The structure of parallel back to back pulse width modulation converters are adopted for multi megawatt high power generation system. The fuzzy based controller is developed to restrain circulating currents flows between the power modules caused by power device discrepancy and asynchronous operation of the parallel units. The control driving signals are generated by individual current control and produced by carrier phase shifting synchronously. The effectiveness of the proposed control strategy is verified through MATLAB simulations.
