Construction of PPPsMechkarevo 1
The built power plant transforms solar radiation into electricity through polycrystalline photovoltaic modules generating direct current and voltage. The resulting voltage is transformed into an alternating voltage by three-phase invertors, then increased to 20kV and the generated electricity is supplied to the medium-voltage distribution grid of the country.
According to the project, a concrete complete indoor distribution system (BKZRU 20kV), with threeoutputs, was installed on the site of the power plant. A transformer 1000 kVАwas installed in it. The MV distribution system was equipped with a switchgear (KRU) 20kV, 100 А, 16 kА. Two transforming stations of the type complete concrete transforming stations (BKTP) 0,4/20 kV, 1000kVАwere installed on the site of the power plant. Each of them was equipped with MV distribution system, with switchgear (KRU) 20 kV.
Along the property perimeter, a wire fence was built, lighting columns were installed, access control system and video surveillance were built.
Project value: BGN 9,9million
Date of completion of the construction and installation works: 29.12.2011
