[Abstract]:With the development of science and technology, the automatic intelligent device with computer technology and communication technology as the core technology has played a great role in the field of power grid operation and control. Meanwhile, with the promulgation of IEC61850 standard by the International Electrotechnical Commission, the popularization and application of electronic transformer, the improvement of power parameter measurement technology, As well as the increasing requirement of reliability and availability of equipment, the concept of intelligent substation has been gradually formed. Through continuous exploration and practice, nearly 100 IEC61850 are regarded as the communication standard. Intelligent substation with "three layers and two networks" structure has been put into production in China. In this paper, the development background of intelligent substation is expounded, and the real-time operation data of intelligent substation is collected and shared in real time. The coordination of grid operation strategy and power dispatching operation has gradually become an important fulcrum to support the strong operation of smart grid. Then the advantages of intelligent substation compared with traditional substation are listed. It is a kind of advanced substation that supports the real time intelligent regulation of power network. The third chapter of this paper introduces the performance, principle and development trend of the primary intelligent component and various kinds of electronic transformers in the actual operation at the present stage. It is pointed out that the comprehensive consideration of the actual situation and the ratio of performance to price is the necessary step in selecting the primary equipment. The emphasis of this paper is on the design and implementation of the intelligent substation. Chapter 4th of this paper describes the construction specification of the intelligent substation. The advanced application functions and requirements of intelligent substation are described in detail. Chapter 5th, combined with the construction of Ma Fang 220kV intelligent substation, describes the concrete construction implementation scheme of intelligent substation. The system design, network structure, function configuration, advanced application and so on, including primary and secondary parts, are presented in detail to meet the functions of substation measurement, protection and control. To ensure the safe and stable operation of the intelligent substation, and provide some reference value for the design work in the future.
