Concept of control and data acquisition system for modern digital power substation

摘要

The article deals with the issue of standardization of approach to definition of modern digital substation is considered. The approaches proposed and partially implemented by equipment manufacturers are described, such as data collection and processing by means of relay protection and automation with the use of proprietary algorithms, wireless and optical current and voltage sensors, etc. The authors propose the use of a unified system for collecting and processing data generated and used in the operation of an electric substation. The structure of the signal transmission system for the main groups of electrical power equipment is described, the requirements for the predictive diagnostics system that allows maintaining the equipment based on its technical condition are described.
