Summary of key solutions

The purpose of the construction of the Novoperevolotskaya SPP 15 MW facility (hereinafter referred to as SPP) is to use renewable energy resources (sunlight), which are converted with the help of modern technical devices - photovoltaic modules into electrical energy.

The projected SPP has an installed capacity of 15 MW and is designed to generate electrical power and transmit it to the 110/35/10 kV Substation Perevolotskaya at the 10 kV design line. The electricity generated by the power plant is used on a general basis to supply electricity to consumers in the Perevolotsky district.

In accordance with the technical conditions for connecting to 10 kV networks, the project provides for the connection of the projected SPP to the buses of the existing 110/35/10 kV Perevolotskaya substation:

  • main power source - section I of 10 kV busbars at 110/35/10 kV Substation Perevolotskaya, equipped with K-XXVI type switchgear cells;
  • backup power source - section II of 10 kV busbars at 110/35/10 kV Substation Perevolotskaya, equipped with K-XXVIII type switchgear cells.

Power delivery to the 10 kV section of the 110/35/10 kV Substation Perevolotskaya is carried out by means of the KVL.

Photovoltaic modules (FEM) with a capacity of 385 W, 380 W, 340 W are adopted as the main generating equipment for SES. FEMs generate direct current voltage.

Construction type - new construction.

The SPP technological scheme provides for the use of the following main equipment:

1) RU-10 kV building:

  • RU-10 kV of ten switchgear cubicles with vacuum circuit breakers;
  • two auxiliary transformers with a capacity of 160 kV ∙ A each;
  • RUSN 0.4 kV;
  • SOPT 220 V;
  • OPS cabinet;
  • communication cabinet;
  • UPS cabinet ASDU;
  • APCS cabinet;
  • RAS cabinet;
  • security and fire alarm cabinet;
  • a shield for the building's own needs.

2) two inverter stations with a capacity of 6250 kVA. Each includes:

  • two inverters Sungrow SG3125HV-30;
  • a two-winding transformer with a split winding LV with a voltage of 0.63 / 0.63 / 10.5 kV with a power of 6300 kVA;
  • switchgear 10 kV from three switchgear cubicles;
  • auxiliaries board 0.4 kV;
  • ACS cabinet;
  • utility networks for their own needs;

3) DC switching cabinets (KShPT) for 250 A output current with 12 inputs;

4) silicon photovoltaic modules STP 385-72Pfh with a power of 385 W - 15184 pcs.

5) silicon photovoltaic modules STP 380-72Pfh with a power of 380 W - 5148 pcs.

6) silicon photovoltaic modules STP 340-72Vfh with a power of 340 W - 21164 pcs.

Provides for the placement of an administrative building (ABK), as well as an open warehouse for storing equipment.

Photovoltaic modules, buildings IS (IS1, IS2), RU-10 kV, ABK, located at the site of the SES, are intended for installation in an open area.

The construction of the Novoperevolotskaya SPP 15 MW has been launched, completion in 2021.
