[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.
