Construction of PPPsGabarevo
The project involves the construction of a photovoltaic power plant. The built power plant transforms solar radiation into electricity through polycrystalline photovoltaic modulesgenerating direct current and voltage. The resulting voltage is transformed into an alternating voltage by three-phase invertors, then increased to 20kV and the generated electric power is supplied to the medium-voltage distribution grid of the country.
According to the project, a concrete completeindoor distribution system (BKZRU 20kV),with one inputand twooutputs,was installed on the site of the power plant.In it, a transformer 0,4/20 kV, 630 kVАwas installed. The MV distributionsystemis equipped witha switchgear(KRU) 20 kV, 630 А, 16 kА. Two transforming stations(complete concrete transforming stations) 0,4/20 kV, 1000 kVАwere installed in the north-eastern and western parts of the property. They were equipped withMV distribution systems, with switchgear(KRU) 20 kV, 630А, 16kА.
Along the property perimeter, awire fencewasbuilt, lighting columns wereinstalled, accesscontrol system and video surveillance were built.
Project value: BGN 12,6million
