Temperature is one of the key factors affecting the performance of hydroelectric generators.The stator is the core component of the unit,and the temperature of the stator region,especially the stator winding,is a key concern for power plant operation and maintenance.This paper outlines the measuring principles of infrared temperature measurement technology,RFID temperature measurement technology,and optical fiber temperature measurement technology.It also conducts experiments to verify the availability and accuracy of these three technologies in measuring stator winding tem-perature.Based on the experimental results and technical principles,the applicative schemes of the technologies are put forward.
