摘　　要：依托新疆阜康抽水蓄能电站工程实例,计算分析了不同水泵水轮机全特性曲线对大波动、水力干扰、小波动过渡过程的影响,研究了采用不同水力设计技术的机组全特性曲线下,机组过渡过程主要控制性参数的定量差别和变化趋势。结果表明,不同水泵水轮机全特性曲线造成的计算结果差异主要是由转轮本身过流特性造成的,不同水力设计技术的水泵水轮机曲线带来的计算结果差异较为明显。在抽水蓄能电站前期的调节保证设计中,需重视全特性曲线的选择。Based on FuKang pumped storage power station in Xinjiang province,this paper analyses the influence of different complete characteristic curves on hydraulic transient process of large fluctuations,hydraulic disturbances and small fluctuations.The difference of quantitative and variation tendency of the main controlling parameters in hydraulic transient process is studied based on complete characteristic curves of different unit hydraulic design techniques.The results show that the calculation results difference of complete characteristic curves are mainly resulting from the flow characteristics of turbine and the difference is significant.The selection of complete characteristic curves is of great significance to the regulation guarantee design at the initial phase of pumped storage power station.
