水轮机运转特性曲线是表示水轮机水头、流量、出力和效率之间相互关系的曲线.在水电站设计中,是选择水轮机及分析最优工作位置的依据;在运行管理中,是供运行人员随时掌握各种运行工况,水轮机各有关参数,作为电网调度和机组负荷分配的依据.它对水电站如何合理放水、提高机组效率和减少单位电能耗水量起着指导作用.因此,掌握运用水轮机运转特性曲线,对水库合理调度,提高水电站经济效益有其重要意义.
Turbine running characteristic curve is a curve representing the relationship between turbine head, flow rate, output and efficiency In the design of a hydropower station, it is the basis for selecting a turbine and analyzing the optimal working position. In operation management, Which is used as the basis of grid dispatching and unit load distribution.It plays a guiding role on how to divert water rationally, improve unit efficiency and reduce unit electricity water consumption.Therefore, to master the application of turbine operating characteristic curve, It is of great significance to rationalize the reservoir and improve the economic benefits of the hydropower station.
