100 ABB transformers for 950 MW Moray East offshore wind farm
UK: MHI Vestas Offshore Wind has contracted Swiss-Swedish multinational corporation ABB to supply transformers for the turbines at the 950 MW Moray East offshore wind farm off the coast of Scotland.
ABB will manufacture 100 WindStar transformers at its factory in Vaasa, Finland, for the Moray Offshore Renewable Power’s Moray East offshore wind project in Scotland. MHI Vestas is the turbine supplier for the project.
According to a press release from ABB, the windfarm will have a capacity to generate 950 MW of renewable wind power in Moray Firth (an inlet of the North Sea), 22 km off the coast of Scotland.
The 295 km² windfarm will contain enormous wind turbines – up to 204 m tall to the turbine’s blade-tip, each with the capacity to generate 9.5 MW of electricity at 66 kV. This will be made possible by ABB’s WindSTAR transformers that are compact enough to be placed inside the wind turbine. They will increase the voltage of the turbine-generated electricity to enable efficient transmission with reduced losses.
ABB’s WindSTAR power transformers are designed to fit inside the wind turbine and can withstand strong vibrations, sudden movements and variable electrical loading, typical of wind power, it claimed. This lightweight transformer is energy efficient and made with biodegradable and safe ester insulation fluid.
