摘　　要：应用多回路理论建立水轮发电机定子绕组内部故障分析的通用数学模型，引入回路关联矩阵减少回路方程总数并自动形成各种故障形式的回路参数，对水轮发电机定子绕组内部故障的稳态性能进行仿真计算，探讨了水轮发电机定子绕组内部故障（如匝间短路、支路间短路等）规律。The general mathematic model for analyzing the hydrogenerator with the internal armature winding faults is established by using the multi loop theory in this paper.The associated matrices of the loops are introduced to reduce the total number of the loop equations and to automatically calculate the loop parameters for various faults.The steady state behaviors of the hydro generator with the internal armature windings faults are simulated.The laws governing the internal faults of the hydrogenerator,such as turn to turn and branch to branch faults,are investigated.
