摘　　要：微机保护的功能是由算法实现的,因此就微机保护而言,保护的算法决定了保护的性能。但目前我国多数电力类高校,由于微机保护实验教学设备的限制,不能开设微机保护算法的相关实验项目。为此,开发设计了微机保护算法辅助教学系统。该辅助教学系统集多种算法于一体,可实现相角、阻抗的计算及显示等功能。它既可用于课堂教学,也可用于实验教学。利用该教学系统,学生可以更好地理解各算法的相关原理、适用范围及优缺点等。The functions of microprocessor-based protection are implemented by the algorithm,sothe algorithm of protection determines the protection performance in the microprocessor-based protection.But,many electric power universities can＇t offer the experiments of digital protection algorithm because of the restriction of digital protection experimental teaching devices at present.So,Microcomputer protection algorithm assisted teaching is developed.The teaching system is a set of multiple algorithms in one,and can achieve the calculation and display of phase angle,impedance etc.It not only can be applied to classroom teaching,but also can be applied to experimental teaching.With this teaching system,students can better understand the relevant principles of the algorithm,scope of application,advantages and disadvantages and so on.
