摘　　要：本文应用张量电网络理论所建立的无刷励磁机通用仿真模型，对１１相无刷励磁机进行了额定工况及故障工况的仿真研究。故障工况包括一个二极管支路断开及一个二极管支路短路情况。分析了熔断器布置的有效性。励磁机电感参数由二维有限元法算得。进行了实验，理论分析与实验结果吻合。The paper analyzes the rated case and fault cases of a 11 phase brushless exciter by general simulation model of exciter,which is based on Kron's tensor circuit.The situations of the 11 phase brushless exciter in case of faults such as open circuit of one of diodes,short circuit of one of diodes,are analyzed.The distribution of fuse is discussed.The inductances of exciter are calculated by 2D FEM method.Agreement of calculated values with test results shows the validity of the method of calculation and theoretical analysis presented.
