洛宁抽水蓄能电站额定水头比选研究

Comparison and Selection of Rated Head of Luoning Pumped Storage Power Station

抽水蓄能电站额定水头的确定直接关系到电站运行的稳定性和经济性.通过分析电力系统需求、机组稳定性及效率要求等方面的制约因素,拟定了洛宁抽水蓄能电站592m、596m、600m、604m、608m共5个额定水头方案.从电站机组运行稳定性、容量效益、经济性等方面对各额定水头方案进行了综合分析比选.结果表明:本电站额定水头在600~604m之间较为合适,推荐采用604m高水头方案.结果为其他类似抽水蓄能电站额定水头的选择提供了一定的参考.

The determination of the rated head of a pumped storage power station is directly related to the stability and economy of the power station operation.From the constraints of the power system requirements,unit stability and efficiency requirements,five rated heads scheme(i.e.592 m,596 m,600 m,604 m,and 608 m)of Luoning Pumped Storage Power Stations were developed.From the aspects of operational stability,capacity efficiency,and economic efficiency of the power plant unit,a comprehensive analysis and comparison were made of each rated water head scheme.The results show that the rated head of the power station is more suitable between 600 m and 604 m.It is recommended to adopt the 604 m high head scheme.The results in this paper provide some reference for the selection of rated heads for turbines in similar pumped storage power stations.
