【摘要】 借助MATLAB/Simulink搭建仿真实验模型,将虚拟实验技术运用到电气工程基础实验教学中,完成传统实验教学的目的。通过对三段式过电流继电保护理论的分析,利用PSB模块采用全波傅式算法构建了电力线路三段式过电流保护虚拟实验系统模型,并对实验模型仿真分析。实践证明,虚拟仿真技术在实验教学中取得了很好的实验辅助教学的效果,可以更好地验证三段式过电流保护理论及各保护范围内保护的配合方式,为学生将来从事电力系统设计和研究提供借鉴。更多还原

【Abstract】 The simulation model of the virtual technique,which was set up by MATLAB/Simulink,was applied onto the teaching of Electrical Engineering Basic Experiment,to completing the traditional experimental teaching. Thorough the analysis of three- section over- current protection’s theory,the virtual experimental model of the electric power line was constructed,and was used to simulation by using the Full Wave Fourier algorithm and PSB model. The results proved the virtual simulation technique in the experimental teaching has achieved good assistant effect in the teaching courses,which also provided a better reference to design and study of power system to the students.更多还原
