摘要：

This paper forms the third in a three-part series describing the theory and application of a new method for analyzing the steady-state and tranSient currents In the stator, rotor and damper windings of a large generator It describes the application of the theoretical method to five classes of problems of practical importance. These are the classic cases of 180 degree out-of-phase synchronization, a three-phase symmetrical short circuit, clearing of a three-phase system fault. internal fault and 6% unbalanced steady-state negative sequence load The paper shows the individual damper bar current and energy or electric power loadings for these cases and, for one example, the time variations of stator and damper winding currents. © 1990 IEEE
