摘要：
Based on rotor slot harmonics theory in the Georgia Institute of Technology, this paper proposed to develop a sensorless temperature estimation method for electrical submersible motor(ESM). This work can realize the demand for the real-time temperature monitoring of ESM worked in the underground 2km deep. To obtain the effective message of slot harmonics, the stator current has been analyzed and used to predict effective parameters of corresponding slot harmonics. In order to improve the identification precision of rotor slot harmonics the expressions of stator and rotor resistance, stator inductance to real time temperature have been obtained by Model Reference Adaptive System (MRAS) based on instantaneous reactive power theory. According to Popov ultra-stability theory design method, PI adaptive law can be used. The theoretical analysis and experiment results validate the correctness and effectiveness of the presented method in this paper. This work can provide some theoretical references for developing the technology of temperature identification for ESM.
