| Abstract: | A supply-side voltage source rectifier(VSR) in doubly-fed induction generating(DFIG) system is designed based on the operation characters of the DFIG.The mathematic model of the VSR is analyzed and decoupled control,feed-forward control and the dual-close-loop control are adapted in the system.The theory analyses and experimental results show that the designed VSR with dual-close-loop can restrain fluctuant DC voltage effectively and it has excel-lent steady-state and dynamic performance. |
