【摘要】 国民经济的快速发展,对我国电气化铁路“高速”、“重载”的发展方向提出了更高的要求。铁路电力系统的信息化和智能化已经成为铁路行业发展的战略制高点和现代化的主要标志。尤其在撤消分局、站段合并的改革大背景下,铁路电力行业迫切需要从全局角度对信息流进行整体分析和统筹规划,为研制管控一体化的铁路电力自动化系统打下基础。 本文首先介绍了铁路电力系统的业务概况和运营管理模式,对改制后的铁路电力业务的组织管理进行了描述。论文在对现场充分调研的基础上,按层次对不同级别的职能部门产生的信息进行分析,指出信息体、信息流向及其目的,并采用流图法给出了详细的信息流图。论文提出采用三层分布式体系结构的电力运营管理系统对铁路局、供电段和基层工区信息进行管理,并就数据编码、软件结构和网络实施方案给出建议。 针对目前远动信息流转的不合理状况,论文从现场业务需求的角度出发,重新规划了数据流向,重点讨论了变电所无人值守情况下远动信息的流转。在此基础上,论文建议将运营管理系统与远动系统集成,构建管控一体化的电力自动化系统,并提出实现真正的管控一体化需要解决的关键问题。 最后,论文对适应“高速”、“重载”要求的综合调度系统进行了分析与探讨。电力自动化系统作为综合调度系统的一个子系统,论文重点分析了其与综合调度信息平台之间的信息交互,并就基于MQ Series消息中间件的信息交互实现方案进行了探讨。更多还原

【Abstract】 With the rapid development of national economy, higher-request has been advanced to the development of high-speeded and heavy-loaded electric railway. Informatization and intellectualization of power system for railway have been the high spot of railway development and the chief sign of modernization. Especially, under the reformation background of subbureau-repealed and department-merged, planning and analysis of data stream from a global perspective have been an active demand for railway power system, which build foundation for developing power supply automation system for electric railway.At first, in this thesis current business situation and running mode of power system for railway are introduced, and organization of power business after the system reform is described. Based on adequate investigation, data stream of every functional department is analyzed. Content, flow direction and purpose of information-exchanged are researched, and detailed flow charting is presented.The thesis Presents power supply management information system (PSMIS) based on Three-ties distributed architecture which is used to manage the information from bureau\department\subbase, while data-coding, software framework and intranet network construction scheme of the system are suggested.whereas the information exchange in telecontrol system is Unreasonable currently, the data stream is re-schemed from the point of view of practical requirement, and put emphasis on the situation of unattended substation. On this base, power supply automation system is pointed out which combine management with control, and key problems how to fulfill management and control in one system are presented.Finally, the thesis makes an approach to comprehensive dispatching system adaptable to the high-speeded and heavy-loaded electric railway. Information exchange is analyzed between comprehensive dispatching system and power supply automation system, which is one subsystem of the former, and the technical proposal based on MQ Series is presented.更多还原
