摘　　要：结合电气工程专业“电力系统继电保护原理”课程教学,介绍了一种电力系统小电流接地保护实验装置的设计,采用零序电流群体比幅原理实现,由集成电路运算放大器构成。大学生通过该设计性实验可较好地理解和掌握零序电流、零序电压的方向性保护这一基本概念,文章还对培养学生创新能力、重视实践教学方面进行了初步探讨,为今后专业教学实践改革作了初步尝试。This paper introduces the design of a new protection device for small current neutral grounding power network, combined with curriculum teaching of principles of protective relaying in power system. It is realized by adopting zero sequence current colony amplitude comparison principle, and is constituted by integrated circuit operational amplifier. The students can understand and master the concept of zero sequence current and zero sequence voltage directional protection preferably through design experiments. Preliminary discussion is put into practice to cultivate the students＇ innovation ability and to pay attention to laboratory teaching. Preliminary attempt is put out for professional laboratory teaching in the future.
