[Abstract]:It has become a new trend of energy development to promote clean energy utilization, ensure energy security and stability, and improve energy use efficiency. Intelligent substation is an important intermediate link in smart grid. The technical level of intelligent substation directly affects the level of smart grid construction. Therefore, the systematic research on intelligent substation design and the formation of advanced and reasonable design plan are of great significance to the construction of smart grid and intelligent substation. On the one hand, the intelligent substation improves the reliability of power supply, on the other hand, it reduces the later operation and maintenance investment by improving the intelligent degree of the equipment. According to the plan, Beijing's new airport will build two 110kV central substations designed according to smart substation standards, and will be put into operation by 2019. Civil airport power consumption belongs to the first class power load, which has great security, reliability and stability for power supply guarantee. Therefore, it is of great significance to study the 110kV intelligent substation of Beijing New Airport. The main work of this thesis is as follows: firstly, the smart grid, the development background of smart substation, the research status at home and abroad are introduced. Secondly, the concept and main technical features of intelligent substation are expounded. Several core technologies of intelligent substation are studied, including: the content and characteristics of IEC 61850 standard, network communication structure, integrated monitoring system, which provides the basis for the later primary and secondary project research; Then, the primary and secondary design of Beijing New Airport No. 2 110kV Station is studied. The network communication structure of intelligent substation is analyzed, and the characteristics of various network structures are compared and analyzed. Select the most suitable network structure, at the same time, compare the station power supply system between intelligent substation and traditional substation, analyze the advantages of intelligent substation integrated power supply system, improve the design content; Finally, the design and research of 110kV intelligent substation are summarized, and the research direction is put forward.
