电气化铁道专用微机保护及故探装置的研究

Study of Microprocessor-based Digital Relaying and Locating Apparatus Used for Electrified Railways

本文介绍了ＷＸＢ－７１型电气化铁道专用微机馈线成莲保护及故障点探测装置的数学模型、装置的硬件、软件以及试验结果。装置采用专用的软硬件，使用特别设计的算法及“分段线性、曲线拟合”的故障点探测算法，可以满足电气化铁道对继电保护的动作速度、测量精度等要求。

This paper deals with the development of a microprocessor-based digital protective relayingand locating apparatus for elctrified railways. The relay algorithms,hardware,software and test resultsare presented in the paper.Aspecial location algorithm based on calculating the reactance from the relaying point to the faultis introduced in the paper. This is sucessfully used in the prototype,and effectively provides satisfactoryaccuracv in fauIt location.
