摘　　要：重点分析了交直流混合供电系统交流、直流同时发生突然短路时的短路电流及电磁转矩 ,给出了它们的解析表达式和计算结果。模拟样机的试验结果证明了文中模型与分析方法的正确性 ,从而可为该类供电系统综合保护提供理论基础。The short circuit currents and electromagnetic torque of a hybrid AC/DC power supply system are analyzed when sudden short circuits occur simultaneously at AC and DC sides, and their analytical expressions and calculation results are presented. The experimental results of the analogue prototype of a machine show that the analytical expressions and calculation method are correct, thus can provide a theoretical basis for composite protection of such kind of power supply systems.
