Abstract
The comparative analysis of the features of the existing and perspective technologies of providing timestamps of the process of continuous monitoring of the stability of power system parameters, according to the concept of smart grid (SMART Grid). A new IEEE-1588 synchronization mechanism is considered that is capable of providing accurate time stamping by packet switching technology that does not require a dedicated network. The experimental data of the results of the research of the equipment of Ukrainian production for transmitting the time scale of the "energy" profile using the RTR protocol are presented. For the technical implementation of the information system for the transmission of reference values of the time scale with certain qualitative characteristics, it is necessary to analyze the features of existing and promising technologies to ensure timing of the process of continuous monitoring of the stability of power system parameters, according to the concept of smart grid (SMART Grid). It is appropriate to take into account the fact that, given the increasing demand for Internet service providers, telecommunications operators are actively developing packet switched asynchronous networks (IP networks) that can be used to reproduce the national time and frequency scale based on the modern RTD synchronization protocol ( Precision Time Protocol) [4] recommended by international standard IEC 61850-9. An important component of the preparation for the technical implementation of the information system is the experimental confirmation of the possibility of using equipment, including Ukrainian production for transmission over the current IP-networks timestamp with an accuracy of ± 1 microseconds, the use of which will create conditions for diversification of synchronization support and reduction of the accident in the intelligent electric power. Test results of a set of equipment of Ukrainian production showed that its basic characteristics meet the requirements of the "energy" profile of RTR and indicate that its technical and economic indicators correspond to the world level.
