Economic Analysis of the Technical Water Supply System for Large-scale Hydro-turbine Generator Unit

通过对巨型水轮发电机组两种典型技术供水方式结构与经济性研究和探讨,以某巨型水电站技术供水系统的经济性算例分析,得出合理的技术供水系统节能幅度可达50%~300%,经济效益非常可观。今后的供水系统方式选择和设计还需进一步完善和改进,致力于巨型水电站技术供水系统具备更强的稳定性与可靠性,减轻运行维护的工作量,对水电站运行的节能降耗具有十分重要作用。

The structures and economics of two typical technical water supply schemes for large-scale hydro-turbine generator units are discussed. The results of the economic analysis on the technical water supply system in a large-scale hydropower station show that the energy saving range of a rational technical water supply system could be as high as 50% to 300%. Thus, the economic benefit is very impressive. For the design of the technical water supply scheme for largescale hydropower stations in the future, further improvements and renovations are necessary to increase the stability and reliability and reduce the maintenance workload, which are of great importance for the energy saving of hydropower stations.
