电流回路二次接线判断的软件实现

The Software Realization of Judgment in the Secondary Connec tion of Current Loop

针对微机保护电流回路二次接线的错误,提出一种利用线路空载投入时,线路电流呈容性的特征,来判断电流回路二次接线是否正确的方法,说明了软件设计思路,并提出电流回路二次接线错误微机自动识别纠正的方法,通过此办法,可以解决微机保护因为电流回路二次接线错误引起的问题。

A new method that can judge the fault of the secondary circuit connection of current loop is presented. This new method is based on the character of capacitive current when no-loaded line places in service. The scheme of software realization is explained. An approach of microcomputer automatic identification, which settles the problem caused by the secondary circuit connection of current loop is presented.
