本文针对当前继电保护课程实验教学存在的问题,提出利用PSCAD/EMTDC软件代替原来的硬件平台进行各类继电保护实验的方案。文中首先分析了新的实验教学方法的优点,然后介绍了几种基于PSCAD/EMTDC软件平台的继电保护实验实例,包括零序电流三段式保护和纵联电流差动保护实验。通过实验中各类故障下的仿真曲线和保护动作情况,验证了软件仿真实验的可行性。

Now protection relay experiments in university have some problems,this paper analyses these problems and presents a new relay experiment scheme based on PSCAD/EMTDC software.This paper describes characteristics of this new experiment scheme,and introduces two experiments based on this scheme.One is three zone protection of zero sequence current,the other is current comparison pilot protection.The results with variables changing processes and relay action are presented,and the feasibility of this experiment is proven.
