[Abstract]:With the development of economy and the progress of society, new equipments and new science and technology are emerging constantly, and the power sources for social development are also increasing. The stability and safety of power system operation is an important condition to maintain the sustainable development of the society, so it is necessary to realize the smart grid. The construction of intelligent substation becomes the foundation and premise, and it is also the inevitable trend of the development of power system substation. Intelligent substation is to use intelligent equipment, intelligent regulation and real-time control of the grid, to achieve the safe operation of the grid, the entire power system has an extremely important role, we must pay attention to the construction and operation of this link. To realize the intelligent construction of substation, the intelligent design of substation is the most important, which is directly related to the starting point of intelligence, information and interaction level of intelligent substation construction. Therefore, the design theory of intelligent substation is deeply studied. It is of great significance to realize the construction of advanced intelligent substation by optimizing the construction scheme of intelligent substation with mature and stable technology and higher reliability and stability. At the same time, it also provides a good theoretical basis for the design of smart grid. In this paper, the theory of intelligent substation design and intelligent equipment are studied in depth. At the same time, the application experience of typical intelligent substation is optimized, and the design of Hangzhou Houpu 220kV intelligent substation is studied and planned. This paper first investigates the research, application and development of intelligent substation, analyzes the typical configuration scheme of intelligent substation and the research status of intelligent equipment, and then expounds the generation, definition, technical characteristics and architecture of intelligent substation. According to the characteristics of substation construction and operation and maintenance, the design principle and network design principle of intelligent substation are expounded, the structure, principle and characteristics of electronic transformer are systematically studied, and the different current and voltage transformers are compared. The configuration scheme of electronic transformer, intelligent switch, intelligent terminal and other primary equipment in Houpu intelligent substation is determined. According to the IEC61850 protocol, the system structure of the intelligent substation and the on-line monitoring system of the equipment are designed. The application status of protection and measurement and control design in the existing secondary system is analyzed emphatically, the existing problems are analyzed, the optimization design of the secondary system in the post 220kV substation is completed, and the 220kV protection and control device and the station control layer equipment are realized. The integrated design of AC / DC system and the integrated configuration scheme of the protection fault information system and the automation system, the network record analyzer and the fault recording system, the computer monitoring system and the anti-error operating system; The network printer, secondary equipment panel optimization, secondary equipment layout and clock synchronization system are optimized and designed. Finally, the configuration scheme of 220kV intelligent substation is analyzed and summarized, and the possible shortcomings of the proposed scheme are pointed out. Its practicability still needs to be checked and verified in the construction of practical intelligent substation, and the development and prospect of intelligent substation in the future are prospected.
