| Abstract: | 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. |
