摘　　要：简单介绍了大容量冲击发电机的工作原理,从大功率试验室的运行角度出发,研究了国产6 500 MV·A冲击发电机短路电流的衰减特性,建立冲击发电机电流衰减的MATLAB仿真模型。对3种典型外阻抗条件下施加不同强励倍数时的短路电流衰减特性进行仿真,初步确定了在不同外阻抗条件下满足相关试验标准要求的强励倍数,对大功率试验室的运行具有参考意义。This paper first briefly introduces the operational principals of short circuit generators. Then from the point of view of high-power laboratory, the attenuation characteristics of the short-circuit current of China-made 6 500 MV. A generator is studied and its MATLAB-based simulation mode is established. Based on the simulations of the attenuation characteristics of short-circuit current, the best choices of force excitation multiples to meet the requirements of relevant testing standards for three typical external impedance conditions are identified. The results of this paper provide a valuable reference for future operation of high-power laboratory.
