抽水蓄能电站首台机组首次起动方式的分析比较

Analysis and Comparison of the First Start-up Mode of the First Generating Unit in Pumped Storage Power Station

针对抽水蓄能电站首台机组首次起动,是选择水轮机工况起动还是水泵工况起动,对两种工况的前提条件、试验顺序以及调试、继电保护方向校核、SFC拖动机组的机械安全问题等进行了技术经济性分析,最终认为水泵工况起动是抽水蓄能电站首台机组首次起动的首选方式。

There has been controversial about first start-up of the first generating unit of pumped storage power plant whether it would adopt the starting-up mode by the working condition of turbine or pump. This paper conducts technical and economic analysis on the problems such as two working conditions＇ prerequisite, test order, commissioning, relay protection check and the mechanical safety of SFC driving generating unit. Finally it concluded that the start-up by the working condition of pump is a preferred mode for the first start-up of the first unit of pumped storage power plant.
