摘要
在简述“程序跳闸”方式利弊的基础上,从汽轮发电机组调速系统和保护系统的可靠性、机组运行的经济性及启动失灵的可能性等方面综合分析“程序跳闸”方式在汽轮发电机组上的应用,建议应慎重选择“程序跳闸”方式。
The advantages and disadvantages of ＂sequential trip＂ are introduced in brief. The applications of ＂sequential trip＂ in turbine generator are synthetically discussed from the reliabilities of speed regulation system and protection system,economy of operation,possibility of actuating breaker failure protection and so on. It is suggested that the ＂sequential trip＂ should be cautiously selected.
