نویسندگان
چکیده
In this study, to ensure stable operation of multi-parallel PCSs, a damping control strategy is adopted restrain resonance characteristics parallel system, and the stability system analyzed. First, mathematical model single PCS built, capacitive current feedback-type active introduced, effect on under proportional-integral (PI) Then, presence grid impedance, established extended where replaced by Norton’s equivalent circuit. The method developed, Bode diagrams are utilized verify that it can effectively suppress spikes system. Finally, simulation four PCSs in built Simulink platform, results support correctness theoretical analysis.
