摘要
为分析变电站中备用电源自投装置(简称备自投)误动问题,做好常见误动问题的应急预案。针对宣城供电公司某220kV变电站直流系统接地引发备自投误动作情况,从备自投装置动作原理深入分析误动的全过程,并提出应对备自投误动的几项改进措施,为变电运检专业提供一种常态化备自投误动应急预案。
In order to analyze incorrect action problems of automatic backup power, a good emergency plan of the incorrect action problem is formulated. Contrary to a DC system grounding accident in a 220kV substation of State Grid Xuancheng Power Supply Company, eventually lead to incorrect action. The operation principle of the whole process of incorrect actions is deeply analyzed, and several improve- ments to deal with the incorrect action of automatic backup power are proposed, a normalized emergency plan of the incorrect action problem is provided professionally.
