本文论述了一种基于自适应神经元方法实现输电线路的单片机反时特性曲线的新技术。该技术在对故障电流量进行测量、分析和判断的基础上 ,采用三种典型的反时限特性方程 ,基于自适应神经元的方法 ,综合考虑线路故障状态的特征 ,使用三个自适应神经元 ,并根据单个神经元的智能控制算法 ,推导出自适应神经元的反时限保护特性算法 ,从而解决了单片机不能实现的反时限指数运算 ,减小或消除了采用查表法的相对误差和时延。该方案具有很强的实用性。

This paper describes a new technique of microcomputer transmission line's protection. The technique adopts three kinds of typical opposite time limit specific equation. On the base of measuring, analyzing and Judging, base on the method of adaptive neurons, synthetically thinking over transmission fault type. Using three adaptive neurons and according to intelligent protection arithmetic of single neuron, inferencing the specific arithmetic of opposite time limit, thus solving a series of problems applying of microcomputer to relative the protection of opposite time limit more than electric current. The plan is strongly practicable.
