Abstract
Relay protection as a guarantee for the safe and stable operation of the power grid, its performance is directly related to the power supply reliability of the smart grid. Therefore, in light of the problems existing in the pilot construction of smart substations, the key technologies for relay protection of smart substations are researched in order to speed up the progress of smart substation construction and improve the operation and maintenance of smart substations. Combining the intelligent substation architecture, the principle of electronic transformers and the network topology of substations, the principle and technical scheme for relay protection of smart substations are analyzed. Analyze the key technologies for line protection, transformer protection and bus protection in smart substations under the direct mode. After nearly 20 years of application, research and development, computer protection has achieved great success in the power system, and has accumulated a wealth of operating experience, has produced significant economic benefits, and greatly improved the level of power system operation and management. In recent years, with the rapid development of computer technology and the widespread application of computers in the relay protection field of power systems, new control principles and methods have been continuously applied to computer relay protection in order to achieve better results and thus enable the use of microcomputers. The research of relay protection has developed to a higher level, and the future trend of relay protection technology is to integrate computerized, networked, intelligent, protection, control, measurement and data communication.
