融合“验证—设计—竞争”三环节的继电保护综合实验设计

Design of comprehensive experiment for relay protection integrating three modules of “verification-design-competition”

结合具备“实验专家系统”功能的自制开放式微机继电保护实验系统,设计了包括验证性实验、设计性实验和竞争性实验三个递进环节的继电保护综合实验。通过设置原理验证性实验环节,强化了对基础理论知识和基本原理的理解与掌握;通过设置模块设计性实验环节,探究了微机继电保护的软硬件技术实现方法,促进了学生实际工程应用能力和创新能力的提升;通过设置网络型竞争性实验环节,激发了学生学习兴趣,有助于学生深入理解电力系统对继电保护的“四性”要求,树立竞争意识,培养合作精神;通过设计“实验专家系统”程序,实现了设计性和竞争性实验环节的自动评价与实验指导,提升了教学互动效率。

Combined with the self-made open experiment system of microcomputer relay protection with the function of “experimental expert system”, a comprehensive relay protection experiment is designed, which includes three progressive modules: verification experiment, design experiment and competitive experiment. The understanding and mastery of basic theoretical knowledge and basic principles are strengthened by setting up principle verification experimental module. By setting up module design experimental module, the software and hardware technical implementation methods of microcomputer relay protection are explored, which promotes the improvement of students’ practical engineering application ability and innovation ability. By setting up networkbased competitive experimental module, students’ interest in learning is stimulated, which helps students to deeply understand the “four characteristics” requirements of power system for relay protection, establish competition awareness, and cultivate cooperation spirit. Through the design of the “experimental expert system” program, the automatic evaluation and experimental guidance of design and competitive experimental modules are realized, and the efficiency of teaching interaction is improved.
