The field-current of a turbo-generator may become negative during certain forms of transient operation when d.c. exciters are used. The use of a.c. exciters operating in conjunction with a rectifier system prevents field current reversal and an overvoltage is induced into the field system owing to the momentary disruption to the m.m.f. balance between the rotor and the stator. The magnitude of this induced voltage determines the peak inverse ratings of the rectifiers and its predetermination is important in the design of the excitation equipment. The paper summarises a simulation model of a synchronous machine capable of predicting this phenomenon and considers, for illustrative purposes, two areas of generator operation that give rise to the rotor over-voltage condition. The results of these investigations are fully discussed. |
