CHECKING THE FUNCTIONALITY OF A NETWORK ON DATA EXCHANGE BETWEEN THE DEVICES ON THE DIGITAL SUBSTATION
Around the world, much attention is paid to the new communication technology IEC 61850. A special place is occupied by the program of Digitization of the electric grid complex of the Russian Federation, according to which 40 digital substations will function by the year 2025. Maintenance of such systems as compared with traditional ones is generally simpler, but they have somewhat different requirements -requirements for the information network. Unfortunately, the standard describes only the requirements, but does not describe the verification algorithm. This article proposes a mechanism for checking the functionality of the device communication architecture at a digital substation using an application of a hardware-software complex developed in the LabVIEW environment that allows an accurate assessment of network compliance with the requirements.
