建构主义学习观结合Matlab仿真在继电保护教学中的应用

微机继电保护是一门理论紧密联系实践、多相关学科紧密融合的课程.入学者需要掌握较多的基础知识,而现代电气工程各学科教学计划决定了继电保护课程的学时有限,因此如何能从复杂的公式中突围出来,使学生将电力系统故障的物理特性与微机保护软硬件平台所体现的电子、自动化等二次控制特性,紧密地结合起来,理解继电保护的基本思想很关键.本文提出在建构主义学习观指导下,引导学生,充分利用Matlab仿真和数据处理技术,开展了“阶段式电流保护”的情境教学,Simulink仿真紧密结合电力系统故障分析,而Matlab的强大数据处理功能用于实现保护算法,为学生提供了互动的平台和案例.实践证明,教学效果良好,满足继电保护教学需要.

Application of Constructivism Learning Method in Protective Relaying Teaching Based on Matlab Simulation Software

Microprocess based protective relaying is a class with the characteristics of fundamental tightly combined with field conditions,and so many correlative classes knowledge fusion,which require the intrant to hold enough electrical engineering background.But the period of class is limited in current teaching system,then how to help the intrant to grasp the fault physical essence in power system and familiar to the modern relay designing is important.In this paper,the method of underling the guidance of Constructivism Learning based on the Matlab simulation software to carryout fault analysis and overcurrent protection zones situational teaching is proposed.Experimental in Shandong Electric power college confirmed the good teaching results.
