大型抽水蓄能机组机械制动系统控制策略研究

The Control Strategy of the Mechanical Brake System for a Large Pumped Storage Unit

本文讨论了机械制动在机组各种工况转换中及异常情况下的控制策略,包括机组正常停机、机械事故停机、电气事故停机、水泵断电、抽水转发电、轴承瓦温异常、机组启动、机组蠕动、高转速机械制动异常投入等情况下机械制动控制策略及安全闭锁,对大型抽水蓄能机组机械制动控制程序设计具有一定的指导意义。

This paper discusses the conditions, including the unit normal control strategy of the large pumped stop, mechanical stop, electrical stop bearing temperature abnormal, unit start, unit creep, mechanical brake ON icance for the large pumped storage unit mechanical brake control design. storage unit mechanical brake under various , pumping loss power, pumping to generating, in high speed, etc. has a certain guiding signif-
