摘要
文章对沙河抽水蓄能电站(简称沙河电站)在2012年以后机组转换效率呈下降趋势进行了系统分析;计算出了一库水的发电效率和抽水效率;对影响机组效率的各种因素进行了详细分析,包括水头、运行方式、无功调节、变压器损耗、协联曲线、环境温度等11个影响因素。为沙河电站提升机组效率的技术改造提供了依据。
In this paper,the unit conversion efficiency of Shahe Pumped storage power station(Shahe Power Station for short)shows a downward trend after 2012,and the power generation efficiency and pumping efficiency of a reservoir of water are calculated.Various factors affecting unit efficiency are analyzed in detail,including 11 factors,such as head,operation mode,reactive power regulation,transformer loss,association curve and environmental temperature.It provides a basis for the technical transformation to improve the unit efficiency of Shahe Power Station.
