牵引供电系统继电保护整定计算软件的开发

本文研究并开发出一套牵引供电系统继电保护整定计算软件.在不同系统运行方式、不同牵引变压器接线形式、不同牵引网供电方式和不同保护配置方案算法的基础上,结合各铁路局对继电保护的运营要求以及各设备厂商的设备装置算法的区别,使用VC++与面向对象编程技术,缩短了系统开发周期,提高了工程分析计算的效率.软件的开发为牵引供电系统的设计提供了技术支持.

Development of setting calculation software for relay protection of Traction Power Supply System

In this paper,it was introduced the setting calculation software of the relay protection which was based on the analysis of the running mode for diverse system,traction transformer connection form,the feeding mode of overhead contact line system and protection configuration scheme,at the same time,it was also integrated the railway administration＇s requirements to the relay protection as well as the difference of device algorithm among different equipment manufacturers.Through using the VC＋＋ program language and the object-oriented programming technology,it was shortened the developing period and improved the efficiency of engineering analysis and image processing greatly.The development of software supplied a strong technical support for the design of Traction Power Supply System.
