【摘要】：配电自动化系统可提高供电可靠性,减少用户停电损失,具有十分重要的意义。配电自动化系统中的配电终端数量多,生产厂家多。各厂家的配电终端信息通信采用私有的信息模型和通信机制,缺乏标准的信息模型和通信机制的支持,导致难以实现不同厂家的配电终端之间的互操作。以IEC 61850为基础,建立配电自动化通信的统一信息模型,实现配电终端信息交互语义的一致,是解决这一问题的有效途径。目前IEC61850尚未覆盖配电领域,本文基于IEC 61850标准建模方法,对配电自动化系统中SCADA、馈线自动化等功能的应用场景进行分析,建立相应功能的逻辑节点,并以柱上开关监控终端为例完成设备的实例化建模,最终搭建测试系统验证信息模型的可用性、有效性,为实现配电自动化设备的互操作,减少维护工作量,解决终端设备的即插即用提供技术支撑。研究内容具体包括:(1)分析了配电自动化系统的应用场景。在总结配电自动化系统结构、功能的基础上,分析SCADA、馈线自动化等功能的典型应用场景,采用面向对象的方法,结合配电自动化系统功能实现的通信过程,确定通信的对象、数据方向以及内容,为建立面向对象的信息模型提供依据。(2)构建了基于IEC61850的配电自动化系统信息模型。在明确SCADA、馈线自动化等功能的信息交互过程后,根据IEC61850标准的逻辑节点建模原则,结合面向对象的统一建模方法,采用标准已有逻辑节点完成SCADA等功能的建模,针对配电网中特有的馈线自动化等功能,通过新定义逻辑节点建立模型,为建立配电终端的信息模型奠定基础。(3)建立了柱上开关监控终端的信息模型。基于IEC61850设备建模方法,以配电终端中的柱上监控开关终端为例,介绍了终端设备的建模方法。使用IEC61850的配置描述语言SCL生成了柱上监控开关终端的ICD文件,并分析了配置文件的结构和内容。(4)搭建了测试系统,验证了本文提出信息模型的可用性与有效性。测试系统包括:配电自动化主站系统与配电终端,在测试系统环境下,使用Web Services映射传输前述定义的柱上监控开关终端信息模型文件,使用IEC60870-5-104映射传输量测数据,可实现基本IEC61850的配电自动化数据的传输。IEC61850标准应用至配电自动化系统,可促进配电自动化系统构建统一的信息模型,实现不同厂家终端设备的互操作与即插即用,简化系统的安装与配置,推动配电自动化技术与智能电网的发展。
[Abstract]:The distribution automation system can improve the reliability of power supply and reduce the loss of power outage, which is of great significance. Distribution automation system in the number of distribution terminals, manufacturers more. The information communication of distribution terminals of various manufacturers adopts private information model and communication mechanism. The lack of support of standard information model and communication mechanism makes it difficult to realize the interoperability between distribution terminals of different manufacturers. Based on IEC 61850, the unified information model of distribution automation communication is established, and the consistency of information interaction semantics of distribution terminals is realized. It is an effective way to solve this problem. At present, IEC61850 has not covered the distribution field. Based on the IEC61850 standard modeling method, this paper analyzes the application scenarios of SCADA, feeder automation and other functions in the distribution automation system, and establishes the logical nodes of the corresponding functions. Finally, a test system is built to verify the availability and validity of the information model. In order to realize the interoperability of distribution automation equipment and reduce the maintenance workload, the monitoring terminal on the column is taken as an example to complete the instantiation modeling of the equipment. Provides technical support for plug-and-play of end devices. The main contents are as follows: (1) the application scene of distribution automation system is analyzed. On the basis of summarizing the structure and function of distribution automation system, the typical application scenarios of SCADA, feeder automation and other functions are analyzed. The object of communication is determined by object-oriented method, combined with the communication process of distribution automation system functions. The data direction and content provide the basis for the establishment of object-oriented information model. (2) the information model of distribution automation system based on IEC61850 is constructed. After clarifying the information interaction process of functions such as SCADA, feeder automation, according to the logic node modeling principle of IEC61850 standard, combined with the object-oriented unified modeling method, the standard existing logical nodes are used to complete the modeling of SCADA and other functions. Aiming at the special function of feeder automation in distribution network, this paper establishes the model through the new definition of logic node, which lays the foundation for establishing the information model of distribution terminal. (3) the information model of on-column switch monitoring terminal is established. Based on the modeling method of IEC61850 equipment, this paper introduces the modeling method of terminal equipment by taking the on-column monitoring switch terminal of distribution terminal as an example. The configuration description language SCL of IEC61850 is used to generate the ICD file of the monitoring switch terminal on the column, and the structure and content of the configuration file are analyzed. (4) the test system is built, which verifies the availability and effectiveness of the information model proposed in this paper. The test system includes: the distribution automation master station system and the distribution terminal. Under the test system environment, the Web Services mapping is used to transmit the information model file of the monitoring switch terminal on the column defined above, and the IEC60870-5-104 map is used to transmit the measurement data. The IEC61850 standard is applied to the distribution automation system, which can promote the distribution automation system to build a unified information model and realize the interoperation and plug-and-play of the terminal equipment of different manufacturers, which can realize the transmission of the distribution automation data of the basic IEC61850, and the application of IEC 61850 standard to the distribution automation system. Simplify the installation and configuration of the system, promote the development of distribution automation technology and smart grid.
