Study on Power Circuit Applied to AC-excitation System for Large Pumped-storage Variable Speed Unit
摘要
Abstract
For designing the ac-excitation system for large pumped-storage variable speed units,the topological structure of the main loop is analyzed and the three-level NPC converters are finally selected.The vector control strategy of the three-level NPC converters is also studied herein.A 5-MW power cabinet prototype is built by using the NPC three-level topology,and the correctness of the topological structure and vector control strategy is verified by power circuit test.This study has great significance on power unit design of the ac-excitation system of 200 MW large pumped-storage variable speed unit.关键词
