Software Based Centralized Protection: commissioning experience

by Alexey Anoshin, Aleksandr Golovin, and Nikita Svistunov, TEKVEL R&D Ltd., Russia

rotective relaying and substation automation (PAC) devices have already evolved a lot during the last 2 decades. Introduction of digital communications between PAC devices using IEC 61850 Sampled Values and GOOSE made it possible to create fully-digital (i.e. with no analog and binary inputs/outputs) protective relays based on commercially available servers. This approach has a lot of benefits that were already discussed in PAC World earlier. Since first mentions the concept of centralization has evolved more into the concept of independent software and hardware for PAC devices, which, however, in most cases would still require centralization in order to achieve considerable costs.
