三相复用子模块型MMC及宽范围优化调制策略
Three-phase Multiplexing Submodule MMC and Its Wide Range Optimization Modulation Strategy
摘要
Abstract
With the large-scale renewable energy development and utilization of desert,gobi,desertification area and offshore wind farms,the demand for low-cost and lightweight modular multilevel converter(MMC)has become more urgent.The three-phase multiplexing arm MMC(TPMA-MMC)provides a new technical solution for the delivery of new energy with its excellent operating characteristics and economy.However,TPMA-MMC faces the narrow operation range and the series connection of devices in the three-phase switching bridge.To address these issues,this article proposes a three-phase multiplexing submodule MMC(TMS-MMC)and introduces an optimization modulation strategy.By constructing a three-phase multiplexing submodule,it realizes multiplexing arm modularization and solves the series connection of devices.Moreover,based on the proposed wide multiplexing period modulation scheme,it extends energy regulation range and further achieves the modulation range to[0,1].Additionally,theoretical analysis demonstrates that,compared to MMC and TPMA-MMC,TMS-MMC exhibits its outstanding characteristics in terms of submodule quantity,operational losses,and energy storages,et al.Finally,a±10 kV/1 MW simulation system and a scale-down prototype are developed to validate the proposed topology and modulation principle.关键词
