汽轮机延时跳闸异常原因分析及处理

Analysis on reason of abnormal longer delay of protective tripping of steam turbine and treatment

以某火力发电厂为例,对一次汽轮机主保护动态传动过程中出现较长延时的情况进行分析,确定了异常的原因,采取了相应的措施,以避免类似事件再次发生。

A longer delay occurred during the dynamic transmission process of the steam turbine master protection of a thermal power plant.The abnormal situation was analyzed,and the reason of the anomaly was determined.The corresponding measures were adopted,and similar incident is avoided.
