开关站实现微机监控后负序电流保护是否保留及如何实现

摘要

研究了开关站现有和新增负荷情况，分析了负序电流的保护作用，研究了实现微机监控后负序电流保护是否可以保留及如何实现，以保证可靠供电。%The research and analysis are made on the existing and newly-added loads and the negative-sequence current protection effect. In order to ensure a reliable power supply, a brief discusstion is made on whether to keep the negative-sequence current protection and how to use it when the micro-computer monitoring and control system works.
