Wind Technology and Transmission Prepares for Future Demands:

Wind Technology and Transmission Prepares for Future Demands:

Today's offshore turbines are basically slightly modified onshore versions. Towards 2020, two different trends will emerge in offshore wind power: turbines will increase in size and they will be installed further from shore . In 2009, the average distance from shore for European wind farms was 12.8 km, but the planned UK Dogger Bank site is 125-195 km offshore. Advanced Control Optimum control is key to smooth and safe running of a wind turbine and the latest systems can measure loads in each of the blades, and are used to smooth out loads in turbulent wind conditions. The same measurements can be used to calculate fatigue effects and can shut down the turbine if damage is critical. The data can also allow the operating strategy to be altered to maximise energy yield. Operating individual turbines in wind farms with different operating rules requires smart sensor technolog...
