Investigation of End Leakage Reactance and Its Influence on the Accuracy in Performance Calculation of Large Double Canned Induction Motors
IEEE Transactions on Industrial Electronics, 2018Co-Authors: Yanping Liang, Lianlian GaoAbstract:The end Leakage Reactance of large double canned induction motors is important for the performance calculation by two-dimensional (2-D) numerical analysis, which calculation accuracy directly affects the calculation results of performances. However, there are many special metallic structures in the end region of large double canned induction motors. Due to these structures, the distribution complicacy of end magnetic fields and the calculation difficulty of the end Leakage Reactance are increased. To solve this problem, a 5-MW double canned induction motor is taken as the research object; 3-D finite element calculation model of its end region is established and solved. The end magnetic field and end Leakage Reactance are obtained. The influence of these special structures on the end magnetic field and end Leakage Reactance are analyzed in detail. Performances of large double canned induction motors are calculated by the 2-D numerical analysis with different end Leakage Reactance coupling. The calculation results of the end Leakage Reactance are indirectly verified through the stator current and power factor as the accuracy of the end Leakage Reactance directly affects calculation results of the stator current and power factor.

Analytical Algorithm for Strand End Leakage Reactance of Transposition Bar in AC Machine
IEEE Transactions on Energy Conversion, 2015Co-Authors: Yanping Liang, Honghao Yu, Xu Bian, Lei Wu, Bing WangAbstract:Calculation of circulating current in transposition bars is the key problem in the design of stator windings, which will determine the transposition type of stator windings. The circuit equation method, in which the calculation of strand end Leakage Reactance in transposition bars is the premise, is widely used in engineering to calculate circulating current. This paper describes an analytical algorithm for the calculation of strand end Leakage Reactance in transposition bars, which is based on mirror image principle. The end Leakage Reactance of strands in transposition bar is calculated by the integral of transposition path discretized into many key points. Contrary to the existing calculation method, the analytical algorithm proposed in this paper is a general method for calculating the end Leakage Reactance, which can simulate the transposition path of strands in the end region for different transposition types. In order to validate the proposed method, the end coil self and mutual Leakage Reactance are calculated by proposed analytical algorithm and finite element method.

IEEE Transactions on Industrial Electronics, 2014Co-Authors: Yanping Liang, Honghao Yu, Xu Bian, Lei Wu, Lichao YangAbstract:Calculation of circulating current in transposition bars is the key problem in the design of stator windings, which will determine the transposition type of stator windings. The circuit equation method, in which the calculation of strand slot Leakage Reactance in transposition bars is the premise, is widely used in engineering to calculate circulating current. This paper describes an analytical algorithm for the calculation of strand slot Leakage Reactance in transposition bars called discrete integral method. The presented method is based on Ampere's circuit law. The slot Leakage Reactance of strands in transposition bars is calculated by the integral of the transposition path discretized into many key points under the proper coordinate system. Contrary to the existing calculation formula, the discrete integral method is a general method for the calculation of slot Leakage Reactance, which can simulate the transposition path of different transposition types. In order to validate the discrete integral method, the circulating current generated by slot Leakage magnetic field of two typical transposition bars is calculated by circuit equation method and finite-element method.
