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.
