摘要针对大型感应电机常见的气隙偏心故障,提出了以绕组函数为核心的多回路建模方法,并对绕组函数法进行了理论推导,最后计算了电机各回路间的电感。基于所给出的计算方法,对一台1 200kW样机建立气隙偏心模型,并通过引入绕组函数平移系数进行更精确的计算。通过对改进的绕组函数法与传统方法以及有限元仿真的偏心电感计算结果的对比,表明改进的绕组函数法应用于计算偏心电机电感参数的可行性,并展示了其在偏心状况下电感参数的变化特点。

Abstract：Air-gap eccentricity is commonly occurred in large induction motors. Based on this fault, winding function approach (WFA) is carried out and theoretical derivation of WFA is also presented. In this way, the inductance matrix in the multi-loop model is calculated. A model of eccentric induction motor (1 200kW) is established based on such method and winding function translation coefficient is introduced to make more accurate calculation. In order to verify the feasibility, the result from modified winding function approach (MWFA) is discussed and compared with that from conventional winding function approach and that from finite element method.

Key words： Induction motor air-gap eccentricity multi-loop theory winding function approach calculation of eccentric inductances
