摘要
本文介绍了水电机组过渡过程的一种数值计算方法(简称直接法),采用该法可直接用存入计算机内并表示征n_1~′-Q_1~′坐标系中的水力机械特性数据,导出了直接法主要算式,并将其计算结果与马歇尔法的计算结果及实测值作了比较。
A numerical method for hydraulic transients in hydrogenerator units is presented such that hydraulic machinery characteristic data which were represented in the ni-Qicoordinate plane and were stored in computer can be utilized directly in the transient calculations. It is called direct method for short. The fundamental formulae of the method were derived and its computed results were compared with those of the Marchal method and with the measured results.
