Design of an industrial solar power plant

Solar power plant "VOLODYMYRTSI"

RENECO, together with its partner TD Royal Group, has developed a business case for the implementation of a ground-based solar power plant under the "green" tariff in Lviv region with an installed capacity of 9.9 MW. The purpose of this case is to create favorable conditions for attracting investments for the construction of a solar power plant in the form of an EPC contract, namely:
  • All rights to the technical documentation and the land plot belong to RENECO-ROYAL GROUP.
  • The development of the project documentation, from design and modeling in PVsyst to the notification to the State Architectural and Construction Inspectorate of Lviv region, was carried out by our company's specialists in order to minimize any costs during the construction phase.
In-depth study of design solutions allowed us to develop the most effective SPP design, taking into account the requirements of such diverse factors as the shape of the site, installed capacity, technical specifications, weather conditions and trends in the Ukrainian market.
  • All technical and legal decisions made are 100% consistent with our internal methodology for the construction of energy facilities.
  • An EPC contract is a complete and integrated set of works involving a single team of specialists and full responsibility for risks throughout the project life cycle.
RENECO-ROYAL GROUP's many years of experience in the construction of both alternative and traditional energy facilities allows us to implement projects of any complexity quickly, efficiently and at a reasonable price.
Design of an industrial solar power plant
The project was implemented with the most efficient and functional layout of equipment placement on the land plot. Thus, for every 1.5 hectares of land, there is 1 MW of photovoltaic field capacity, which technically and economically satisfies the business case. In addition, the entire field is on-axis and with the same spacing, which speeds up and reduces the cost of pile driving and minimizes geodetic errors. The photovoltaic field is conditionally divided into five clusters. Each cluster includes a 1600 or 2500 kVA KTP according to the design solution. Electric energy (EE) transformation is performed in one stage from 0.48 to 35 kV.
This minimizes electricity losses during transformation and meets the requirements of the connection specifications. The inverters were designed to be installed in close proximity to the PV modules, which technically allows the use of a cheaper PV cable with a cross-section of 4 mm2. Power collection boards (PCBs) combine two inverters each, which transport electricity with a voltage of 0.48 kV. In accordance with international practice, the design solutions take into account power losses that do not exceed 2% on the inverter - switchboard - substation section. At the same time, the 0.48 kV cable with a maximum cross-section of 240 mm2 was designed as small as possible. The used SPP monitoring and control system provides the most modern and reliable PLC data transmission interface (via power cables), as well as extensive dispatching capabilities and functionality.
