压力反射波迭加法在压力水流运动及水电站调压室计算分析中的应用

The Application of Reflected Wave Pressure Accumulation Method in Surge Shaft Analysis

本文为作者于1990年6月在下马岭水电站4~＃机进行增加负荷试验的成果,并用压力反射波迭加法的原理和基本方程对上述情况下调压井中水位变化进行了计算,其结果与试验所得结果符合得较好。此外,还对调压室主室面积减少及引水管道长度减小的情况也应用压力反射波迭加法对调压井中水位变化进行了计算。

Published in this paper is the results of increased load test on No.4 generating unit of Xiamaling hydroelectric power station conducted by the author in June, 1990. The results were checked by calculations of water level variation in the surge shaft under above mentioned conditions by using reflected wave pressure accumulation method. The calculated results conformed fairly good to the test results. In a bid for further improvement of the design, calculations had also been made on water level variation in the surge shaft with the shaft length reduced.
