摘要
Previous research on the series-connected pulsewidth modulation current-source-converter-based offshore wind energy conversion system is conducted without considering the effects of the independent control of offshore converters and the cables connected between offshore converters and between offshore and onshore converters. In the present work, a further study on the system is conducted taking these factors into consideration. First, the equivalent circuit of the system is derived, based on which two items are selected to evaluate the performance of the system: the dc-link current and the dc-link voltage. Second, both the dc-link current and the dc-link voltage are derived and analyzed, and the worst case is quantitatively and qualitatively defined. Third, the performance of the system with dc filters is investigated. Finally, both simulation and laboratory-scale experiments are provided.
