The electric power industry uses a large number of different automated technological systems - relay protection controllers, control systems, quality control and electricity metering systems, etc. As computer technology develops, the complexity of problems that are solved using technological process automation tools also increases. Analysis of a large amount of data on the parameters and operating modes of equipment is impossible without correct information about the moments in time when these events were recorded. Thus, the basis for the operation of automated technological systems is the system of uniform and accurate time, which establishes the unity of time scales in all controllers and information collection systems. This article discusses the features of constructing time scale synchronization systems for electric power networks, taking into account the requirements of different generations of automation equipment.
