AB - In this paper, a novel and simple method is proposed for estimating the stator winding real-time temperature of the air-cooled hydrogenerator. Firstly, the structure and temperature characteristics of the hydrogenerator are analyzed. Then, a data-driven method for estimating the stator winding real-time temperature is proposed, and the implementation steps are illustrated in detail. Finally, the real-time temperature of the stator winding is estimated by the proposed method with different days, which is validated by the test. The result shows that the proposed method can well predict the temperature of the stator winding, which provides a new idea for the temperature measurement of the large hydro-generator.
