摘要
采用IEC推荐的直流衰减法,运用系统辨识理论识别其衰减电流的数学模型,并通过该模型推导出同步机参数、时间常数及频率特性。
A method of d.c.current decay test recommended by IEC is applied in this paper. The mathematical model of decay current is identified by using theory of system identification, and the parameters,time constants and frequency characteristics of synchronous machine are derived from the above mentioned model.
