摘要
直流微型电网(微网)的保护技术是确保微网安全可靠运行的重要基础。基于直流微网特点,分析了保护系统设计中的注意事项,阐述了直流微网常见的故障类型,总结了直流微网保护系统的研究现状和关键技术,并对直流微网保护技术的后续研究方向提出了建议。
Protection technology is an important foundation to ensure safe and reliable operation for direct current micro-grids. Based on direct current (DC) micro-grids features, analysis was made to cautions in protection system design. This paper described DC micro-grids common fault types, summarized study present status and key technology of protection system for DC micro-grids, and raised subsequent study suggestion for DC micro-grids protection technology.
