CJSC Intertechelectro is continuing reconstruction and technical upgrade of the 220 kV Rayonnaya substation (town of Vladimir). The recovery is performed under the OJSC FSK UES investment program. The first autotransformer has been delivered to the site and is being prepared for installation.
The 160 ton equipment has been shipped form the factory and delivered by railway to the station of Yur’evets. The transformer has been transported to the substation by road transport using a special platform.
The 125 MVA ATDCTN-125000/220/110-U1 autotransformer haw been manufactured by OJSC HK «Elektrozavod». This equipment complies with world standards under performance, reliability, installation and operation convenience. As compared to existing counterparts, it has smaller weight and reduced electric losses as well as extended service life.
At present oversite excavation is completed, the 220 kV existing power line offset has been made, the 110 kV existing power line offset is prepared, foundations and main building steel structures for the SF6 220 and 110 kV complete switchgears and 10 kV close switchgear have been made. The 220 kV complete switchgear building cladding has been started, foundation pit was excavated, 6 kV close switchgear building foundation is being arranged, oil collector is being assembled, gatehouse building pedestal is being erected.
The 220 kV Rayonnaya will be the 1st close facility of the Vladimir power system. Its advantages as compared to traditional open substations are compactness, environmental and fire safety, noiselessness and equipment protection from external influence. The reconstruction involves installation of new 220/110 kV autotransformers and 220 and 110 kV complete switchgears. The substation will be equipped with up-to-date relay protection and automatic equipment MPUs, DCS and a set of modern communication systems. After the recovery the substation output will be 460 MVA
The 220 kV Rayonnaya substation having installed capacity of 346,5 MVA was put in operation in 1963 and is serviced by MES of Center, branch of OJSC FSK UES. The plant is one of the main power supply sources for the town of Vladimir consumers including such large factories as OSJC Vladimir electric motor plant and OJSC Vladimir tractor plant.
