Abstract

Large power generators, especially hydropower generators with a few hundred megawatts power and a few ten kV voltages, have high inertial power while operating, so they must not only withstand the operating torques and forces during operation, but also the transient forces that may arise at the time of failures, while also taking into account economic considerations. It is worth mentioning that for a large hydroelectric generator, these transient electromagnetic forces are several times the operating forces.
