With the development of society, the importance of the power grid has become increasingly prominent. Therefore, with the UHV power grid as the backbone grid, the coordinated development of all levels of power grids, and the unified and strong smart grid with the characteristics of informatization, digitization, automation, and interaction will definitely play a role. Important role. As the development direction of the power grid, smart grid will play a huge role in power generation, transmission, transformation, distribution, and electricity use. In the future power system, the substation is the most important link. The basic requirements of current power users for power systems have shifted to safer, more reliable, and more economical. Electric energy plays a very important role in improving human living standards and accelerating economic development. How to improve the safe and stable operation of the power system, how to ensure the safety and reliability of power supply, and how to increase the power load to load the local economic development, etc. The problems that need to be solved urgently in today's power system. The design of the substation is related to the safe and reliable operation of the entire power system. Therefore, in-depth systematic research on substation design and designing a set of technically mature, economical and reasonable design schemes are of great significance to the safe and reliable operation of substations.
