| Abstract: | In this paper, the effects of the electromagnetic process and/or excitation regulatang of the generators on hydro-turbine governing systems are investigated. By using a MATLAB-based software platform for simulating the hydraulic-mechanical-electromagnetic combined transient process, the dynamic processes under load disturbance condition with different load mode are calculated. Those studies show that the electromagnetic process and/or excitation action have evidently effects on speed governing of the hydroelectric generating units. So it is necessary to account for those effects for hydro-turbine governing system research. |
