[Abstract]:Digital substation is a modern substation which consists of intelligent primary equipment and networked secondary equipment. It can realize information sharing and interoperation among intelligent electrical devices in substation. With the construction of UHV power grid as the backbone of the grid, the goal of a strong smart grid with coordinated development of all levels of power grid has been put forward, and the construction and development of intelligent substation has been put forward to the process. Digital substation is the basis of intelligent substation development and an important node of smart grid construction. This paper studies the design method of digital substation based on 110 kV digital substation project. This paper first introduces the research status of substation automation technology and digital substation, discusses the main technical characteristics of digital substation which is different from traditional substation, and expounds the overall technical framework of digital substation. Secondly, for the intelligent primary equipment of digital substation, the working principle, structure and technical performance of electronic transformer and merging unit are discussed, and the realization mode of intelligent primary equipment based on intelligent terminal is studied. The configuration principle and method of electronic transformer, merging unit and intelligent terminal are put forward. Thirdly, for the network secondary equipment of digital substation, the network hierarchy structure of substation is discussed, and the structure and characteristics of station control layer, interval layer and process layer are expounded according to the order of network architecture stratification. According to the characteristics and requirements of each layer, the network configuration scheme of station control layer, interval layer, process layer and secondary equipment configuration principle are given. Finally, the paper introduces the actual engineering situation of a 110 kV digital substation, gives the concrete implementation scheme of the digital substation, and gives the overall design scheme, the distribution device design scheme and the networking scheme. The scheme of monitoring and protection system is explained and analyzed in detail.
