水轮机运转特性等效率曲线极值点的确定

绘制水轮机综合运转特性曲线是水轮机选型计算中必不可少的一步。其中等效率曲线最高和最低点的画法一直很粗糙。本文在水轮机相似理论的基础上,提出了一种方法,能够更准确地确定等效率曲线的最高最低点。

Determine The Extreme Point of Curve of Efficiency On The Operation Performance Curves of Turdbine

On the operation performance curves of turbine, it is a simple thing to draw curve of efficiency. But the highest peint and lowest point are not determined by old method. This article shows a new way to find out the position of these highest dot and lowest dot exectly. The basis of this new method is the similar priniciple of turbine.
