This paper reports on analysis and calculation results for probing into the feasibility of using the generator as a varying frequency vibration exciter, under various modes of operation, in the case of an imported 200 MW set. 该文对一台进口200MW机组发电机在不同运行工况下作为激振源时变频励磁激振的可行性及其效果进行了分析和计算,所得的结论可为变频励磁激振的实施提供依据。
