摘要
介绍了直流线路低电压保护27DCL的原理,分析了其保护思想、动作行为,以及保护间相互配合的关系,得出了27DCL不合理的地方,并提出了改进措施。
The principle of the DC line under-voltage protection （27DCL） was introduced in this paper. The protection strategy,the action results, and the coordination between the other protections were analyzed. The unreasonable part of the 27DCL was found, and the improvement method was composed.
