一种实现数字式阻抗继电器的新方法

A New Method to Realize the Digital Impedance Relay

本文利用人工神经网络技术，提出了一种新的数字式阻抗继电器的实现方法。该方法适用于各种不同动作特性的阻抗继电器。且该法计算量很小，有利于高速保护的实现。同时如需改变保护的动作特性，可由运行人员在现场完成。

A new method to realize the digital impedance relay based on microcomputer is described in this paper.The new method utilizes ANN(artificial neural network)and is available for all kinds of relay characteristics which are used in power system.Some examples are used to test the new algorithm and the results show the algorithm performs well.
