摘 要在电力系统中，因运行环境、可操作性问题的限制，现场对同步发电机测试不太现实，因此，利用软件仿真的方法对同步发电机进行仿真讨论就显得极其重要，此次设计的容便是是同步发电机突然短路仿真，不仅要了解同步发电机短路情况，还要学会 MATLAB 的应用，MATLAB 是现今在电路、信号与系统、数字信号处理、图像处理和电力系统仿真上应用最广泛的，本次设计我们用到 MATLAB 中的 Simulink 仿真工具进行同步发电机突然短路仿真，Simulink 模块库为用户提供了大量的系统模块，我们用到其中的电力系统模块库，选择好元器件进行参数设置后，然后通过 MATLAB 软件中的 Simulink 建立同步发电机的仿真模型，对所列出来的短路故障进行仿真，观察示波器中的波形，更好地掌握同步发电机短路故障状态下的各特性，对各短路故障进行了仿真实验，从仿真结果可以更直观地了解同步发电机短路故障状态下的特性指标，尽量避开发生短路故障或及时对短路故障做出相应的正确措施，更合理选择保护装置。关键词：Simulink；短路故障；仿真ABSTRACTIn the power system, the operation environment, the problem of synchronous generator testing is not realistic, therefore, simulation research on synchronous generator simulation is very important, the design of the synchronous generator sudden short-circuit simulation, not only to understand the synchronous generator short-circuit situation, MATLAB is the circuit, signal and system, digital signal processing, image processing and power system simulation of sudden short circuit simulation, Simulink module library for users to provide a large number of system module library, select good ponents parameter settings, and then through the MATLAB software S software Simulink software, and then through the MATLAB software. In Imulink to establish the simulation model of synchronous generator, the short circuit faults are simulated, the oscilloscope waveform, better grasp the characteristics of the synchronous generator short-circuit fault state, the short-circuit fault simulation ex...
