摘要
提出一种与电力系统微机继电保护课程相配套的简单、经济的微机保护实验装置，具有概念清晰、便于观察和操作等特点。同时给出了相应的硬件及软件框图；并采用了判别故障方向的简单方法，具有简化编程和判断准确等特点。
In this paper,a simple and economical experiment instrument for micro-computer protection that coordinates with the course of power system microcomput-er protection is presented. The instrument has the characters of clear conception,easy observation and operation. The involved hardware and software graphs of theinstrurnent are advanced. The simple method of judging the fault direction is accept-ed,which has characters of simplifying program and accurate judgement.
