摘　　要：基于柔性直流输电的直流电网技术具备灵活、安全的潮流控制能力,将越来越多地成为大规模清洁能源发电、海洋群岛供电及构建新型城市电网的首选技术方案。直流电网核心装置电压源换流器、直流断路器等都利用到全控电力电子器件以实现电能的变换,因而器件参数性能对这些装置有着极大的影响。从直流电网各核心装置的需求分析着手,详细讨论了不同装置对器件电气特性、封装形式的要求,提出具有针对性的定制化设计、协同优化设计等关键技术,最后对适用直流电网发展的未来新型器件进行了展望。1Able to control power flow flexibly and securely, DC grid technology based on VSC-HVDC will become preferential technical solution for large-scale renewable power integration, oceanic island power supply and new urban grid construction. Key equipment of DC grid such as VSC valve and DC breaker utilizes power electronic devices to realize power conversion. Their parameters and performance have great impact on equipment itself. According to demand analysis of DC grid key equipment, this paper discussed requirements of different devices on electrical characteristics and packaging, then proposed key technologies such as customized design and collaborative design optimization. Finally, this paper prospected new type power devices adapted to DC grid development.
