Abstract
Considering the capacity optimal configuration problems of the IPFC(integrated power flow controller) in the cophase traction power supply system, a satisfactory optimization compensation strategy was proposed. The method could decompose the load current real-timely into fundamental positive-sequence active component, fundamental positive-sequence reactive component, fundamental negative-sequence component and harmonic component. By giving expected power quality parameters, it adjusted the compensation ratios of negative, reactive and harmonics instantaneously, so that the IPFC capacity could be allocated between power quality compensating parameters optimally and real-timely. On the base of compensation current reference signals, a converter one-cycle control strategy was proposed, which inhibited the steady and transient tracking error within one power period satisfactorily. The theoretical analysis and simulation verify the feasibility and correctness.关键词
