RF Prime Minister Visited the Digital Distribution Zone of Moscow Region Networks

On 4 September 2018, Prime Minister of the Russian Federation Dmitry Medvedev paid a working visit to the first digital distribution zone of electric networks of the Moscow region.

Prime Minister was accompanied by the Minister of Energy of RF Alexander Novak and Moscow region’s Governor Andrey Vorobyov.

General Director of Rosseti Pavel Livinsky demonstrated the effect of implementation of the new digital distribution zone, which includes Sloboda substation in Istra district, to the members of the delegation.

Substation No. 836 Sloboda of the Pavlova Sloboda sector of the Moscow Unified Distribution Grid Company (MOESK) was put in operation in 1998 in Pavlova Sloboda village of the Istra district in Moscow region. Istra region is among the most dynamically developing areas, characterized by a high level of electricity consumption and connection rates of new consumers. In 2011, a large flow of requests for grid connection demanded a complex modernization of S/S Sloboda with transition from 110 to 220 kV. The facility is specific with 220, 110, 10 and 6 kV power units allocated there to ensure power flow, depending on the load level. The 220 kV voltage is supplied via five power lines for connection to the unified energy system of Russia, the 110 kV equipment is used for connection with the supply centers of MOESK. Using the 6 and 10 kV networks, the substation provides a direct power supply to consumers: large industrial facilities, cottage estates and social infrastructure facilities.

During the tour, the hosts simulated an emergency situation for the Premier and demonstrated how the breakdown is identified and the power supply is restored via a fallback circuit.

In the course of the tour, Dmitry Medvedev asked about the country of origin of the power equipment, used at S/S Sloboda. Pavel Livinsky explained that the overwhelming majority of units are Russian-made or localized.

Some of transformer equipment at S/S Sloboda is equipped with Izolyator 110 and 220 kV RIP bushings.

The works to create the digital distribution zone were started in July 2018 and will be completed by the end of 2019. Istra district was selected for a pilot project for a reason: it is one of the most densely populated ones (320 thnd inhabitants) and dynamically developing in Moscow region.

The consumers of S/S Sloboda are large industrial enterprises of Istra district, such as Izolyator plant, Velkom, Danfoss, Grundfos, Lactalis Istra, Archbum, residential area with over 2.5 thnd people and No.62 Oncology hospital.

The power complex of the Moscow region is one of the largest in Russia. The region accounts for about 2.4 % electric power generated and 4 % o- consumed in Russia. Production of electric power is done by 10 large power plants, owned by six generating companies and captive power stations of various organizations. The total installed capacity equals 8000 MW.
