摘　　要：为了高效地实时监测发电机定子绕组温度,采用典型的指纹模型和蒲莹温度模型对其进行了结构分析和计算比较。结果表明:指纹模型计算简单,变量项便于工程分析,系数有物理意义,并且计算精度高,因此更适合应用于发电机定子绕组温度的在线监测。To effectively monitor the real-time temperature of generator stator windings, structural analysis and comparison were conducted to a stator respectively with the typical Fingerprint model and Puying thermal model. Results indicate that the Fingerprint model is more suitable for on-line temperature monitoring of generator stator windings for its simple calculation, variables convenient for engineering analysis, physically meaningful coefficients and high calculation precision.
