三相同步发电机运行仿真与GUI设计 摘要 同步发电机广泛应用于诸多领域。随着科技进步，自动化程度在不断地提高，因此同步发电机也需要不断改进来适应日益提高的自动化程度的需求，而同步发电机是电力系统中最重要和最复杂的元件，它的突然短路的暂态过程所产生的冲击电流可能达到额定电流的十几倍，这种情况下对电机本身和相关电气设备都可能带来严重影响，所以从技术和安全上考虑直接进行试验可能性很小。因此，对同步发电机运行进行仿真具有很大的必要性。 本设计是借助MATLAB的强大实验仿真功能和GUI设计功能，通过编写同步发电机某些故障状态下的M文件进行仿真实验得到仿真结果，并通过GUIDE来创建并进行设计仿真系统的登录界面以及仿真实验的主界面，从而更好地实现实验时的人机交互，清晰显示了个故障状态下的仿真波形，有利于大家掌握同步发电机故障状态下的各个性能指标。 关键字：同步发电机；运行仿真 ；MATLAB ；M文件；图形用户界面 Three-phase Synchronous Generator Running Simulation and GUI Design ABSTRACT Synchronous generators are widely used in many fields.As the science and technology advancing,the level of automation is gradually improved,synchronous generators also need to be meliorated to adapt to the demand of constantly improvement of automation level.But synchronous generators are the most important and complex elements in the Power Systems.Their impulse current may reach more than ten times of the rated current when they suddenly short-circuited,which may bring serious impact to the machine themselves and the related electric equipments.Considering from the technical and safety ,it unlikely to do this kind of test directly .Therefore,it is quite essential to simulate of the running synchronous generators. This design is by means of the powerful simulation functions and GUI design tools of MATLAB, by analysing some kinds of trouble states of a synchronous generator to get appropriate M-file to simulate to get simulation results,and through GUIDE to create and design simulation system login interface and simulation experiment host interface.Thus, we can easier to achieve the human-computer interaction during the experiments.According to be showed with each trouble state simulation waveform, we can pay less efforts to master the synchronous generators fault conditions of each performance indicators.
