JdC has developed a complete range of Transformer Stations (PT) specific for Solar Photovoltaic Parks.
With powers from500kVA to 9000kVA, these transformation stations are intended to transform the energy generated by photovoltaic inverters at Low Voltage (400 to 800V), to the Medium Voltage level (10 to 30kV) that allows interconnection to the electrical grid.
They can be built including the inverters in the PT itself (centralized inverters), or include the framework for interconnection with decentralized inverters. For smaller parks, the PT may include theSCADApark and functionPPC, thus allowing an “all in one” solution.
JdC designs and manufactures Transformer Stations using four construction technologies:
The “Concrete Base” solution uses a concrete base that functions as a support for the installation of the equipment that makes up the Transformer Station: the medium voltage equipment, the Medium/Low Voltage transformer, and the low voltage panels for control, protection and interconnection of inverters.
This base also functions aslaying slabof the Transformation Station on the ground, and howretention basinof transformer oil.
Medium and Low Voltage switchboards can be of the “outdoor” or “indoor” type, in the latter case the insulation from the surrounding environment is provided by “sandwich panel” metal panels.
For small parks (type UPP – Small Production Unit of 1MW), JdC produces an “all in one” solution that includes the PCPark SCADAinstalled in the low voltage compartment of the PT.

The “Skid indoor” solution is based on a Skid-type metal structure, on which the medium voltage equipment, the Medium/Low Voltage transformer, and the low voltage panels for command, protection and interconnection of inverters are mounted.
The electrical panels are operated indoors, with insulation from the outside environment provided by structural metal panels with polymeric insulation (sandwich panels).
Withdimensions of a metal container, can be easily transported.
The “Metallic Container” solution uses a20” containerto house the various equipment that make up the Transformation Station:
Their size and weight allow them to be easily transported.
