沙河抽水蓄能电站非电气量保护的优化

Optimization of Non-electricity Protection for Shahe Pumped-storage Power Station

针对沙河抽水蓄能电站非电气量保护存在的误动率高问题,对机组非电气量保护配置、运行情况、动作情况进行专项研究,提出非电气量保护防误动优化方案。经过保护优化,有效地减少了机组非计划停运,提高了机组运行可靠性。

Since the Shahe Pumped-storage Power Station has been put into operation, the error operation rate of non-electricity protection was high. Aiming at this problem, Shahe Power Station made specific research on the configuration, operation conditions and actions of non-electricity protection and put forward the optimal scheme of protecting error action of non-electricity protection. This optimization measure can effectively decline the unplanned outage and enhance the operation reliability of units.
