控制与维护是使水电机组安全、可靠、高效地完成发电任务的基本生产活动。文中首先建立了综合描述系统运行状态控制与健康状况维护的系统运行模型,类比控制系统的运动状态反馈、控制决策和控制执行闭环框图,定义了包括设备健康状况反馈、维护决策和维护实施3个环节的维护系统闭环框图,并分别对健康状况监测、维护决策和维护实施中的自动化技术进行了讨论和展望。
Control and maintenance are the basic production activities that enable hydropower units to safely, reliably and efficiently complete their power generation tasks. First of all, a systematic operation model that describes the system operation state health and health maintenance, the motion state feedback of analog control system, the control decision-making and the closed-loop control diagram of control system are established firstly. Three health-state feedbacks including equipment health status, maintenance decision and maintenance are defined Closed loop diagram of the maintenance system, and discussed and predicted the health monitoring, maintenance decision-making and automation technology in the implementation of maintenance.
