摘要
叙述了北京地区八里庄变电站1997年“2.19”事故保护误动的情况,重点介绍了变压器差动保护误动装置检查试验情况,利用微机继电保护测试装置实现了故障的还原再现,查清了该保护误动的真正原因。
The maloperation of transformer differential protection occurred in Balizhuang substation on Feb. 19, 1997 is presented. In order to find out the reason of maloperation, the microcomputer based protective relaying tester is used to check up the transformer differential protection for replaying the fault, and the checking up process is emphatically described.
