Gottesgabe and Alttrebbin solar park
Gottesgabe und Alttrebbin,
Germany
  • Construction of central inverter skids for two ground-mounted PV plants. 
  • For each park, a DC power of about 150 MWp is generated by bifacial glass-glass modules, routed via the ZWR skids and transformed to 110 kV via a feed-in substation in order to be able to feed in the power at the grid interconnection point. 
  • 30 pieces of 4.8 MVA (AC) inverter stations per PV park with transformers and MV switchgear 8DJH36.
  • Central inverter SINACON PV.
  • The components were mounted on galvanized frames (skids).  
  • Assembly and commissioning as well as trial operation.
  • The modules are connected to parallel strings by means of DC string collectors and connected to the inverters with a DC main cable. The medium voltage in the park has an operating voltage of 31.5 kV. Some central inverters were additionally equipped with Statcom functionality. 
  • Extremely short cable runs due to medium-voltage transmission directly at the converter. 
  • Arc-safe design, compact SF6 system in outdoor housing, environmentally friendly Midel transformer oil.
