Abstract
A system and method for monitoring temperature and detecting a temperature rise of a rotating electric machine with high accuracy. A temperature monitoring system for a rotating electric machine includes: sensor data storage that stores values measured by an in-coil temperature sensor and a physical quantity sensor in the rotating electric machine; an in-machine temperature predictor that predicts a temperature by use of the value measured by the physical quantity sensor; a strand temperature calculator that calculates a relationship between a temperature of the strand and a temperature measured by the in-coil temperature sensor, based on the predicted temperature; and a strand temperature predictor that predicts a temperature of the strand from the value measured by the in-coil temperature sensor, and from the relationship between a temperature of the strand and a temperature measured by the in-coil temperature sensor calculated by the strand temperature calculator.
