摘要
近年来电力推进技术越来越广泛地应用于各类军用舰船,为满足航速要求,大型舰船的推进电机功率已达几十兆瓦级。变频器作为连接电网和推进电机的桥梁,是舰船电力推进系统中的重要设备之一。针对大功率变频器,文章介绍了基于模块化多电平(MMC)拓扑的有源前端(AFE)变频器的工作原理和控制策略,并通过在PSCAD/EMTDC仿真平台下搭建仿真试验模型,验证了其在舰船电力推进系统中的适用性和可行性。
In recent years,electric propulsion technology has been widely applied in naval ships.To meet the speed requirement,the power rate of propulsion motor has been reached dozens of MW.As a bridge between the grid and propulsion motor,frequency converter is the vital part of electric propulsion system.The working principle and control strategy of MMC-based Active Front End(AFE)converter are introduced,and the simulation model of MMC has been built in PSCAD/EMTDC.Its applicability and feasibility in ship electric propulsion system are verified.
