【摘要】 随着我国铁路高速铁路建设的发展，研制高速铁路综合调度系统是提高铁路运输效率，保证高速铁路运行安全的迫切需要。牵引供电调度自动化系统作为高速铁路综合调度系统中一个重要的子系统，在高速铁路运行环境下，与其它七个子系统一起联合运行的效果，将直接影响综合调度系统的整体性能，因此，采用仿真技术，在实验室中完成对牵引供电调度系统功能及其工作环境的仿真，实现仿真条件下系统运行，模拟外部环境的变化对系统的影响，以及研究如何提高系统的通信性能是非常重要的。 本文首先简单地介绍了牵引供电系统的组成和运行原理，针对牵引变电所的运行特点，详细讨论了变电所仿真系统中各模块的设计方法，并对于不同的运行状态，提出了相应的仿真方法。根据提出的电能分配计算原理，着重讨论了主接线图的电压、电流追溯算法，并对数据库结构和图形界面管理进行了讨论，实现了牵引变电所的仿真。 其次，本文在阐述了传统电气化铁道牵引供电调度系统构成的基础上，分析了其通信方式和网络结构，指出了该系统目前存在的主要问题。随后，分析了以太网的实时性，认为它可以满足供电调度系统严格的实时要求。通过比较现有的几种通信结构，选取Publish／Subscribe(发布／订购)结构作为系统的通信模式。在此基础上，尝试性地提出了基于Publish／Subscribe结构的通信解决方案。 最后，本文根据提出的通信解决方案，采用ActiveX技术，实现了一个基于P／S结构的消息中间件，并且组建了一个由四台计算机构成的实验系统，对该中间件进行测试，基本能够满足系统要求。更多还原

【Abstract】 With the development of high-speed railway, it is very necessary to begin the research of Integrated Dispatch System of High-speed Railway (IDSHR) because the system can help to improve the efficiency of railway transportation and ensure the security of high-speed railway. The Traction Power Supply Dispatch Automation System (TPSDAS) as an important sub-system, its performance of operation with other seven subsystems may influence IDSHR’ s performance directly. So it is very important to simulate the function of TPSDAS and its operation conditions by adopting simulation technology, and implement TPSDAS’ s operation, simulate the impact to the system by outer conditions, and study how to improve communication performance of the system.Firstly, author simply introduces the composition of Traction Power Supply System and its operation principles. Based on its operating features, the design method of each module in this system is discussed. Different methods of simulation are provided according to different conditions. On the basis of the principles of power distribution, backward arithmetic of voltage and current in main diagram is discussed in detail. The database structure and graphic interface management are also discussed to implement the simulation of substation.Secondly, author introduces the composition of traditional Traction Power Supply Dispatch System for electrical railway, then analyses its communication mode and network structure, and points out the existing problems of the traditional type. Subsequently, the real-time capability of Ethernet and whether it can satisfy the system’s strict requirement for real-time are analyzed. By comparing the existing communication structures, Publish/Subscribe is selected as communication mode of the system. Based on this mode, this paper tries to propose a scheme to resolve these problems.Finally, according to the proposed scheme, a message-oriented-middleware based on Publish/Subscribe is implemented by adopting ActiveX technology. And a testing system composed of four computers is constructed to test this middleware. Though the test, this middleware can satisfy basic requirements of this system.更多还原
