An innovative distribution pilot in the Russian city of Ufa is proving that modern smart grid technologies are suitable for Russian city networks.
The pilot is jointly headed by the Russian Joint Stock Company (JSC) and Bashkirian Power Grid company (BPGC) according to T&D World.
The move is part of an effort to reach levels of reliability and energy efficiency more in step with grid modernisation efforts in other modern cities. Russia and its republics which form part of the Commonwealth of Independent States, are seen to be lagging behind in global best practice.
Ufa is the capital of the Republic of Bashkortostan in the Volga federal district, with a population of more than 1 million. The city has a strong industrial sector.
The joint JSC-BPGC distribution network straddles several voltage levels, at 10kV, 6kV and 04.kV respectively, with 110kV and 35kV primary substations.
Underground low voltage cable networks at 10kV and 6kV are based on feeders in a total of seven geographical regions. Distribution substations have partial real-time operation and monitoring capabilities, although remote control is limited to key 10kV and 6kV switching substations.
These limitations are considered to have an adverse effect on management and maintenance, as well as outage restoration abilities in many major Russian cities.
