摘　　要：针对现有方法无法对电力系统故障进行技术上与安全性实验的问题,文中基于MATLAB对电力系统故障进行了建模及仿真分析。在介绍电力系统故障分析方法的基础上,对单相故障进行理论分析,分析故障点处电压电流之间的关系,建立电力系统同步发电机、变压器模块等主要元件模型,并设置了恰当的仿真参数。文中以三相短路故障为例,基于该模型对其进行仿真分析,分析端口与故障点电压电流的特性,并将其结果与实际计算结果进行对比。结果表明,仿真与计算的结果之间具有良好的一致性,验证了该仿真模型的准确性、有效性。For the existing methods,it is impossible to carry out technical and safety experiments on power system faults. This paper is based on MATLAB to model and simulate power system faults. This paper introduces the analysis method of power system faults,theoretically analyzes single-phase faults,analyzes the relationship between voltage and current at fault points,establishes main component models such as power system synchronous generators and transformer modules,and sets simulation parameters.Taking the three-phase short-circuit fault of power system as an example,the simulation model is established and simulated. The dynamic characteristics of the power system can be accurately observed,and the results are compared with the actual calculation results to verify the accuracy of the results.
