基于双电阻辨识方法的感应电机暂态温度计算
|
摘要
感应电机的状态监测是其稳定可靠运行的关键,电机的运行温度是其一项重要的指标。为了评估感应电机的运行温度,提出一种基于双电阻辨识方法的感应电机暂态温度计算方法。首先,利用基于转子磁链的模型参考自适应对当前时刻电阻阻值进行修正。进而基于上述参数可以得到电机损耗,用于计算感应电机暂态温度。在此基础上,根据金属电阻与温度的近似线性关系,得到未修正的暂态电阻阻值。重复上述计算,可以实现对电机定转子侧温度的观测,理论分析与实验结果验证了所提方法的可行性与有效性。
The monitoring condition of an induction motor(IM) is critical to its stable and reliable operation.Temperature changes could be a useful indicator of the running motor.In order to monitor the temperature of the running motor,this paper proposes a feasible method to estimate the transient temperature of IM based on the double-resistance identification.On the basis of the resistances at the moment,the correction of resistances can firstly be realized by the model reference adaptive system based on the rotor flux.And then,the transient temperature of IM is adopted to obtain based on the loss model,which is calculated by the parameter above.On this basis,without correction,transient resistance value is able to be calculated by the basis of linear relationship between metal resistance and the temperature.The theoretical analysis and experiment results show the effectiveness and practicality of the proposed method in this paper.
