This paper mainly studies the teaching innovation and practice of the comprehensive training of relay protection in the graduation internship of electrical engineering and automation majors.First of all,the background and significance of the comprehensive practical training for relay protection are introduced,and the steps and measures for the implementation of the practical training teaching are described in detail,including the configuration and connection of experimental equipment,the process of experimental operation,etc.Secondly,an innovative decomposed task-driven approach is proposed,which integrates the comprehensive training of relay protection into the internship,so that students can deeply study the working principle and application technology of relay protection device,and improve their practical operation ability and problem-solving ability.Finally,the teaching evaluation standards and practical training report requirements are discussed.This comprehensive training and teaching innovation has a positive impact on the quality improvement and career development of students,and also has important reference value for the improvement and development of graduation internships in electrical engineering and automation majors.
