Wind Resource

With offshore wind becoming a key source of renewable energy there exists a requirement for the acquisition of meteorological information at the sites allocated for development. Installation of a conventional, static, meteorological mast is costly. Multiple masts are required to obtain data at several positions in a large offshore wind farm, which further increases the cost of gathering such data. A structure that has mobility for relocation about the site has the potential to reduce costs whilst improving data capture coverage. As such, an instrumentation platform in the form of a floating structure which can be moved easily is desirable. This work discusses the development of a low-motion, lightweight, floating platform with tunable motion response as a basis for a repositionable meteorological measurement station. Wind speed and direction measurements are acquired at a range of heights in the atmosphere through the use of a pulsed Lidar (light detection and ranging) system. The motions of the platform have been analyzed both numerically and experimentally, and the performance of the platform in a range of seas is good.

The turbulence intensity is an important parameter in wind energy resource assessment, and is the main basis of the wind turbine design and equipment shaping. This paper introduces the methods of turbulence intensity calculation, especially the method based on turbulence transport models in CFD. The CFD method of Meteodyn WT is applied to calculate turbulence intensity of wind farm site in complex terrain of some area, and the simulation is compared with measured date by the mast and the simulation based on the line model. The results show that CFD method of Meteodyn WT provides good results of turbulence intensity. It is significant that the CFD method is applied in wind resource assessment and micrositing of wind farm.
