Calculation of Stator Leakage Reactance of Fifteen-Phase Induction Motor Under Symmetrical Fault Condition
摘要
Abstract
To analyze the operation performance of multiphase induction motors under symmetrical fault condition,the stator leakage reactance in the equivalent circuit should be predicted. The stator slot leakage reactance,harmonic leakage reactance and,end-winding leakage reactance of the fifteen-phase induction motor are analyzed using an incidence matrix model to reflect the five-phase and ten-phase open-circuited fault operation. The analysis results indicate that the stator slot leakage reactance is unchanged and the harmonic leakage reactance is increased,while the end-winding leakage reactance is reduced for fifteen-phase induction motor with full-pitch concentrated stator winding under five-phase and ten-phase open-circuited conditions. Thus, there is no exact integer relationship of the stator leakage reactance between symmetrical fault and normal condition. The short-circuit reactances of a prototype fifteen-phase induction motor are measured with locked-rotor test under normal and ten phases opened-circuited conditions. The analytically predicted results are compared with the measured results,where good agreements are achieved.关键词
