铁路电力自动化系统组网方式探讨

Discussion on Networking Mode of SCADA

介绍铁路电力系统常规结构和铁路通信系统采用的通信方式,铁路电力自动化系统的发展和通信系统发展密不可分,两者互相影响共同发展。文章对铁路电力自动化系统早期采用过的典型组网方式及结构进行了介绍,并对目前新建铁路中普遍应用的新型组网方式进行了阐述。同时对铁路电力自动化系统及通信系统的发展给予深切的期待和展望。

This article introduces conventional structure of power system for railways and telecommunication method of telecommunication system for railways.Development of supervisory control and data acquisition（SCADA） for railways is inseparable from telecommunication system,impacting mutually and developing together.The article reviews the typical networking modes and structures,adopted in SCADA for railways in early phase,and presents the new networking mode applied generally in newly built railways.Ultimately,a deep dissection of expectation and prospecting are suggested on the development of SCADA and telecommunication system for railways in the future.
