基于Matlab/Simulink的三段电流继电保护在教学及实验中的应用

Application of Three-stage Current Relay Protection Based on Matlab/Simulink in Teaching and Experiment

电流保护是继保专业的教学基础,一般都采用实验手段对其进行验证。为了提高实验手段和效率,通过实例进行三段式电流保护的计算,利用MATLAB/Simulink建立对应的仿真模型,并进行相应的动作仿真和线路故障分析,验证了三段式电流保护的行为特性和模型的正确性,给其他实际工况对象奠定仿真基础。

Current protection is the teaching basis of relay protection,and it is generally verified by experiment.In order to improve the experimental methods and efficiency,the article uses examples of three-stage current protection to verify,the corresponding simulation model is established with MATLAB/Simulink.It is correct that The characteristics and model of the three-stage current were verified,and simulation foundation of the other simulation is established。
