500kW Micro-grid Power Conversion System

MJR has design, constructed & Installed a 500kW Floating Offshore Power Conversion System

DG500 Tidal Energy Converter  deliver’s and dissipate generated energy at the offshore test site as if connected to an onshore grid.

The bespoke system is based on ABB’s industry ACS880 drive hardware platform modules engineered into a unique system architecture that allows bi-directional low harmonic energy transfer, complete with an energy storage system for periods when the device is not generating.

MJR’s scope of supply included the design of power conversion system to enable stable power injection from the DG500 device via umbilical into 500kW dummy load; power management system, 70kWh energy storage system, interface with spar buoy auxiliary systems, PLC and SCADA system houses in a 20ft offshore container.
