Additional Details

The ABB megawatt station is a turnkey solution designed for largescale solar power generation. It houses all the electrical equipment that is needed to rapidly connect a photovoltaic (PV) power plant to a medium voltage (MV) electricity grid. All the components within the megawatt station are from ABB's product portfolio.

Turnkey-solution for PV power plants:

The ABB megawatt station design capitalizes on ABB's long experience in developing and manufacturing secondary substations for utilities and major endusers worldwide in conventional power transmission installations.

A station houses two ABB central inverters, an optimized transformer, MV switchgear, a monitoring system and DC connections from solar array. The station is used to connect a PV power plant to a MV electricity grid, easily and rapidly. To meet the PV power plant's demanded capacity, several ABB megawatt stations can be combined.

Compact design eases transportation:

The steel-framed insulated container comes complete with a concrete foundation. A thermally insulated inverter compartment enables operation in harsh temperature and humidity environments and is designed for at least 25 years of operation. The hollow concrete foundation has a double floor within the inverter compartment. This provides easy access for cabling. Additionally the small inverter footprint makes the container compact and easy to lift via a standard crane, thereby simplifying transportation. The complete ABB megawatt station weighs only 20 tons. At 50 m3 , the container's volume is some 15 percent smaller than equivalent solutions.
