Contents of this chapter
This chapter provides an overview of the PVS-175 medium voltage station (MVS). It also
includes layout, type designation label and type designation information.
Product overview
The PVS-175 medium voltage station connects a group of inverters to a medium voltage
power grid. This solution is constructed around a skid house that contains:
• MV transformer —transforms low voltage from inverters to medium voltage for the
power grid.
• Auxiliary service transformer —supplies power to the AC cabinet and auxiliary
components of the MVS.
• MV switchgear —connects to the power grid. It is also the main protecting, switching,
breaking and disconnecting equipment of the medium-voltage side of the solar power
plant.
• AC cabinet —contains all parallel connections to the inverter inputs and the auxiliary
service boards (required for the autonomous function of the MVS). Note that the AC
cabinet also includes an additional space for customer use (e.g. communication board,
etc.).
• Free area —for optional customer communication board and UPS.
External dimensions
The MVS is constructed over a skid suitable for transportation inside a 20 HC container
with,
• External dimension (length, width, height) = 6060 x 2450 x 2900 mm
• Total weight = 15 ton.
