铁路新老电力远动系统整合方案及其关键技术研究

随着国家铁路建设的加快,新、老电力远动系统(SCADA)之间的整合越来越成为铁路运营单位面临的一个重要问题。从铁路远动系统整合的实际需求和关键技术出发,讨论新的电力远动系统数据传输模型需要满足的技术要求,提出了一种基于数据发布/订阅模型(DDS)的新一代电力远动系统的系统构建方式,并结合洛襄铁路电化改造项目,详细介绍新老电力远动系统整合的一个具体方案,对系统整合的原则、方法和特点进行总结评述,期望能够对各供电段的新、老电力远动系统的整合提供有益的参考。

Research on Integration Scheme between Old and New Electricity Supervisory Control and Data Acquisition Systems and Its Key Technology

With the acceleration of national railway construction,the integration between the old and new electricity supervisory control and data acquisition system(SCADA) becomes more and more an important issue faced by the railway operating units.In light of the requirements of SCADA system and its key technologies,the technical conditions of data transmission model of new SCADA system is discussed in this paper.Further,a model of system building for new SCADA system is proposed which is based on date dissemination/subscribe model(DDS).Also,taking Luoyang-Xiangfan Railway electrification reconstruction project as an example,a specific integration scheme between new and old SCADA system is given in this paper.And the summarization and comment on the principles,methods and characteristics of system integration are carried out,which is hoped to be useful reference for the system integration between the new-built SCADA system and the existing system.
