水电机组振摆监测保护系统的应用可为其安全稳定运行、突发事故预防、经济效益提升、科学维护及计划检修向状态检修的过渡提供技术保证。本文以SSJ-9000机组振摆保护系统在白山水力发电厂的应用为例,详细介绍了以SJ-90B振摆保护装置为现地核心采集处理单元的SJ-9000系统结构、配置、功能与特点,客观分析评价了系统对机组运行状态的实时监测保护作用,为水电机组振摆保护系统应用工作的展开阐明了一条切实可行的技术实施路线。
The application of hydropower monitoring and protection system for hydropower units can provide technical assurance for its safe and stable operation, accident prevention, economic benefits improvement, scientific maintenance and the transition from planned maintenance to condition maintenance. In this paper, taking the application of SSJ-9000 unit vibration protection system in Baishan Hydropower Plant as an example, the structure, configuration, functions and features of SJ-9000 system with SJ-90B vibration protection device as its core collection and processing unit are introduced in detail. Objectively analyzes and evaluates the real-time monitoring and protection function of the system on the operation status of the generating units, and clarifies a feasible technical implementation route for the application of the hydropower protection system.
