水电站调保计算的优化法

METHOD OF OPTIMIZATION IN THE CALCULATION OF HYDROELECTRIC STATION REGULATION GUARANTEE

本文用优化分析方法,提出水轮机转轮综合特性曲线中的单位流量Q_1~′及效率η,采用导叶开度α和单位转速n_1~′为变量的优化方程表示。它具有形式简单,拟合显著的优点,用于水电站调节保证计算十分方便。

In this paper Optimal Analysis is applied to describe the unit flow Q'1 and the efficiency η of the characteristic curve of hydraulic turbine revolver.The directoi leaf opening a and unit rotative velocity n'1 are adopted as the variable of the optimal equations,that made the equations have following advantages; simpler form,marked simulation, and it can be conveniently used in the calculation of hydroelectric station regulation guarantee.
