【摘要】：经济的飞速发展不仅对电力能源的需求与日俱增,也对国家电网的安全运行水平提出了更高的的要求,智能电网的研究成为新的发展趋势。变电站作为电力系统的关键节点,迫切需要提高其智能化。对大量未纳入电力HMI/SCADA系统的35kV及以下等级的变电站、开闭所的智能监控系统的研究具有重要意义。其中电力通信管理机作为变电站监控系统中通信网络与监测设备之间的枢纽设备,已经成为变电站安全经济运行的必要技术手段。目前,正在使用的通信管理机多种多样,但真正适合35kV变电站监控系统的并不多。因此有必要开发研制一种基于全新硬件平台的新型网络型通信管理单元。论文首先介绍了变电站监控系统的概念,回顾了变电站监控系统国内外发展历史。论文详细分析了变电站监控系统的基本功能和系统结构,并对35kV变电站监控系统采用的分层分布式结构进行了相关的理论研究。在分析了通信管理机功能需求的基础上,采用"ARM11+Linux"为核心的通信管理机软硬件平台,完成了嵌入式Linux操作系统的移植和通信管理相关应用程序的开发。采用友善之臂的Mini6410作为目标机,将安装有RedHat Enterprise Linux 5的PC机作为宿主机,建立嵌入式软件的交叉开发平台。按照系统要求对现有的Linux内核进行裁剪,给出了移植BootLoader、移植Linux内核和制作yaffs2文件系统的方法及详细过程,并且完成了Qt的移植,使得后续开发的Qt应用程序能在通信管理机上运行。软件采用模块化设计,主要包括串口驱动模块、系统设置模块、数据通信模块以及数据显示模块。论文设计的基于GPRS的通信管理机,可以实现RS485通信、GPRS无线数据传输以及图形化界面显示。经测试,论文所设计的通信管理机能很好地与监控主机进行实时数据传输。该设计能满足变电站监控系统快速数据处理和网络通信的要求,为变电站快速接入调度系统提供了新的解决方案,亦可作为变电站远动通道的最佳补充。
[Abstract]:With the rapid development of economy, not only the demand for power energy is increasing day by day, but also a higher requirement for the safe operation level of the State Grid. The research of smart grid has become a new development trend. As the key node of power system, substation urgently needs to improve its intelligence. It is of great significance to study the intelligent monitoring system of the switch station for a large number of substations which are not included in the power HMI/SCADA system and the substations below the level. As the hub equipment between the communication network and the monitoring equipment in the substation monitoring system, the electric power communication management machine has become the necessary technical means for the safe and economical operation of the substation. At present, there are a variety of communication management machines in use, but few are really suitable for 35kV substation monitoring system. Therefore, it is necessary to develop a new network communication management unit based on new hardware platform. Firstly, the concept of substation monitoring system is introduced, and the development history of substation monitoring system at home and abroad is reviewed. In this paper, the basic functions and system structure of substation monitoring system are analyzed in detail, and the hierarchical and distributed structure used in 35kV substation monitoring system is studied theoretically. Based on the analysis of the functional requirements of the communication manager, the transplantation of the embedded Linux operating system and the development of the communication management related application program are accomplished by using the software and hardware platform of the communication management machine "ARM11 Linux" as the core. The Mini6410 with friendly arm is used as the target computer, and the PC computer with RedHat Enterprise Linux 5 is used as the host computer, and the cross-development platform of embedded software is established. According to the requirements of the system, the existing Linux kernel is clipped, and the method and the detailed process of transplanting the Linux kernel of BootLoader, and making the yaffs2 file system are given, and the porting of Qt is completed. Enables the subsequent development of Qt applications to run on the communication manager. The software adopts modularization design, including serial port driver module, system setting module, data communication module and data display module. The communication management machine based on GPRS designed in this paper can realize RS485 communication, GPRS wireless data transmission and graphical interface display. After testing, the communication management function designed in this paper is very good for real-time data transmission with the monitor host. The design can meet the requirements of fast data processing and network communication in substation monitoring system, and provide a new solution for substation fast access dispatching system. It can also be used as the best supplement of substation telecontrol channel.
