摘要
本文推导出具有多台机组、多条尾水洞而共调压室的水电站复杂尾水系统调压室水位波动微分方程和计算其调压室稳定断面积的通用公式,用特征线法对其非恒定流进行计算,调试出通用电算程序。列举了一个实际工程作为算例。
In this paper,the differential equation of oscillation of surge chamber's water level and the general computing formula for required minimum surge tank for the stability of the complex system,which possesses turbo-generator sets,tailrace tunnels and a surge chamber,have been developed.The method of characteristics is introduced for the computation of transient flow and a computer program is proposed for the complex tailrace system.To serve as an illustration of its application,a concrete engineering example is also given.
