三相异步电动机定子绕组温度在线监测

On-Line Monitoring the Temperature of Stator Windings of Three-phase Induction Motors

基于过程辨识理论，依据三相异步电动机在αβ坐标系下的数学模型，建立了定于绕组温度预测的数学模型，并以80C552单片机为核心构成三相异步电动机定子绕组温度在线监测硬件与软件系统，通过实验验证了此方法的正确性与可行性．

Based on the theory of process identification, according to the mathematical model of threephase induction motors in αβcoordinate,the mathmatical model of the temperature forecast of the stator windings is developed. Based on 80C552 single-chip micro-processor, the hardware and software system of on-line monitoring the temperature of the stator windings of three-phase induction motors are designed.The experiments verify the correctness and feasibility of this method.
