Minimising yaw brake noise

Minimising yaw brake noise
Maintenance of wind turbine generators (WTGs) aims to sustain efficiency levels and ensure continued reliability, whilst also dealing with any other concerns that may be raised. One issue that is becoming more common is noise generated by the operation of the equipment in the nacelle, as opposed to any noise from the turbine blades. Svendborg Brakes has turned its expertise on yaw brake noise and developed a solution that can be applied to the majority of installations.

Wind and solar power could meet 80% of U.S. electricity demand

Wind and solar power could meet 80% of U.S. electricity demand
The United States could reliably meet about 80% of its electricity demand with solar and wind power generation, according to scientists at the University of California, Irvine; the California Institute of Technology; and the Carnegie Institution for Science. However, meeting 100% of electricity demand with only solar and wind energy would require storing several weeks’ worth of electricity to compensate for the natural variability of these two resources, the researchers said.

Five-year agreement to optimise wind turbine foundations

Five-year agreement to optimise wind turbine foundations
In order to optimise the design of foundation structures for offshore wind turbines, Ørsted and the University of Oxford have signed a five-year research agreement. Continuing to drive down costs is critical for the offshore wind industry and Ørsted is working with several universities to help improve the design and performance of offshore wind turbines. A major collaboration on wind turbine design is currently ongoing with Durham University and this new agreement with the University of Oxford will focus specifically on the foundation design.

Full power output achieved at offshore wind farm

Full power output achieved at offshore wind farm
Electrifying news just in from Ørsted’s Race Bank Offshore Wind Farm! Full power output has been achieved at the North Norfolk wind farm. Installation of the wind turbines at Race Bank first began in May 2017 and following successful completion of the 240-hour acceptance tests of all 91 turbines, and the 200-hour test of the full park, the project is now capable of generating its full capacity of 573MW.

Wind turbine OEMs: lower prices fuel structural growth

Wind turbine OEMs: lower prices fuel structural growth
According to Macquarie's latest research, the most important trend in the wind industry in 2017 was the decline in average selling prices (ASP) of wind turbines. The company forecasts ASPs to decline by ten percent YoY, which is likely to put pressure on margins across the value chain. However, this trend does have positive consequences for the company's medium term growth outlook for the industry. Macquarie believes this is currently being overlooked by the market due to the short term focus on margin pressure.

Long live the wind turbine!

Long live the wind turbine!
Achieving an online availability of about 98%, wind turbines give operators approximately one week in the year when planned maintenance can be completed. It is essential to use this time efficiently, concentrating on the most important issues, which can be identified using preventative maintenance techniques. Jason Horton, Regional Operations Director (South) at Sulzer, looks at the benefits of creating a partnership with a specialist maintenance provider in terms of improved lifespan and reliability of wind turbines.

Lowering the cost of offshore wind turbines

Lowering the cost of offshore wind turbines
Results of a new research project has shown how offshore wind turbine foundations can be designed in a smarter way to reduce production costs, that will ultimately make the alternative power source cheaper. The Ørsted-led PISA research project has now been rewarded with the Fleming award from the British Geotechnical Association.
