水布垭电厂计算机监控系统优化改造

Optimization Renovation of the Computer Supervision and Control System in Shuibuya Hydropower Plant

基于水布垭电厂原分布式双环网络计算机监控系统存在的问题,对系统硬件进行了更新改造。采用可靠性高的双星型网络,将转速、电压、电流等重要信号实施冗余配置,使统一对时系统、电源、同步检查闭锁继电器等方面均满足现有国家标准要求,提高了系统的可靠性和自动化水平。

Considering the problems found in the distributed double-loop network computer supervision and control system in Shuibuya Hydropower Plant,an optimization renovation of the system hardware is carried out.The double-star type network with higher reliability is adopted.Redundant configuration is set for important signals such as speed,voltage and current.Thus,the requirements of the national standards on the unified timing system,power supply and synchro-check lockout relay are satisfied,and the reliability and automation level of the system are greatly improved.
