水电站机组LCU控制流程设计及实施

简要地介绍了计算机监控系统机组LCU配置和结构,对机组LCU控制流程设计进行了比较详细的说明。机组控制流程设计以安全、可靠、合理、操作方便为原则,除设计了开机、停机、紧急事故停机、一般事故停机等常规控制流程外,为了使机组试验过程中达到不同的运行状态,增设了冷备用空转、空载开机、热备用空转、空载开机等多种试验控制流程。试验控制流程的设计简化了操作步骤,减轻了值班人员的工作强度,对于防止误操作的发生也起到一定作用。

This paper brief ly introduces the conf iguration and structure of the computer supervisory control system unit LCU,and makes a detailed introduction to the control f low design of the unit LCU.The control f low design of the unit is based on the principles of safety,reliability,reasonableness and convenience of operation.In addition to the general control f low,such as start-up,shutdown,emergency shutdown and general accident shutdown,cold standby idling,no-load startup,hot standby idling and no-load idling are added in order to achieve dif ferent operation conditions during the unit test.A variety of test processes such as loading and starting.The design of the test control f low simplif ies the operation steps,reduces the working intensity of the personnel on duty,and plays a certain role in preventing the occurrence of misoperation.The LCU conf iguration and structure of the unit are brief ly introduced,and the design of the control f low of the unit is introduced in detail.The control f low of the unit is designed according to the principle of safety,reliability,rationality and convenience of operation.Besides the general control f low such as start-up and shutdown,a variety of test f low are added in order to make the unit run in different states during the test.The design of the test control f low simplif ies the operation steps,reduces the working intensity of the personnel on duty,and plays a certain role in preventing the occurrence of misoperation.
