摘要
构建高效、低耗、可靠的多电压等级直流配用电系统是实现直流型源、荷灵活接入和高效匹配的重要途径。随着电力电子技术的发展,直流配用电技术及经济优势逐渐显著。从电压等级序列及供用电模式、直流配用电系统接线及接地方式、直流配用电系统关键装备、系统运行控制、系统保护方法和示范应用6个方面介绍了国内外直流配用电研究的最新进展,对当前理论及应用的不足进行了论述。最后,对直流配用电系统未来研究的重点方向进行了展望。
The construction of an efficient, low consumption, reliable DC distribution and consumption system with multi-voltage grade is an important way to achieve flexible access and efficient matching of DC power and load. With the development of power electronics technology, the DC distribution and consumption has tremendous potential for its obvious advantage in technology and economic. In this paper, the latest progress of 6 key topics, such as voltage level sequence and supply mode, system grounding mode, key equipments, operational control, protection method and application demonstration were comprehensively expounded. On this basis, the insufficient of current research were discussed. At last, the research directions of each key topic was introduced and forecasted.
