In the Magadan Region, reconstruction of the PSN 220 kV "Orotukan"
OJSC Magadanenergo (part of the RAO Energy Systems of the East holding) has completed the reconstruction of the 220 kV Orotukan substation in the Yagodninsky district of the Kolyma. The expansion of the substation was dictated by the launch in 2013 of two hydroelectric units at the Ust-Srednekanskaya HPP (JSC RusHydro) with a total capacity of 168 MW, the press service of the company reported.
The substation is an element of the scheme for issuing the capacity of a hydroelectric station to the Magadan energy system. In general, more than half a billion rubles was spent on the reconstruction of the substation. PS "Orotukan" increased by three linear cells. As a result, its distributed power has increased significantly, it has become the largest junction substation of the Magadan energy system. Within the framework of the project, modern gas-insulated breakers, current and voltage transformers, disconnectors with polymer insulation and motor drive, the latest devices of relay protection, automation and communication were installed on the expandable part of the SS 220 kV Orotukan. In addition, the substation is equipped with a video surveillance system that allows personnel to monitor the operation of equipment remotely in real time. In the future, this will significantly reduce the time to search for damage.
