ROTATING ELECTRIC MACHINE TEMPERATURE MONITORING SYSTEM AND TEMPERATURE MONITORING METHOD

摘要

To provide a rotating electric machine temperature monitoring system and temperature monitoring method capable of accurately detecting a temperature rise in a rotating electric machine.SOLUTION: A rotating electric machine temperature monitoring system (100) includes a sensor data storage device (102) that stores the measured values of a temperature sensor in a coil and a physical quantity sensor provided in a rotating electric machine (101), an in-machine temperature predicting device (105) that predicts the internal temperature of the rotating electric machine using the measured value of the physical quantity sensor stored in the sensor data storage device, a wire temperature calculation device (106) that calculates a relationship between the temperature of a wire and the measured temperature of the temperature sensor in the coil on the basis of the internal temperature of the rotating electric machine predicted by the in-machine temperature predicting device, and a wire temperature predicting device (103) that predicts the temperature of the wire on the basis of a relationship between the measured value of the temperature sensor in the coil stored in the sensor data storage device, the temperature of the wire calculated by the wire temperature calculation device, and the temperature measured by the temperature sensor in the coil.SELECTED DRAWING: Figure 1
