Electromagnetic Interference on Large Wind Turbines
نویسندگان
چکیده
Electromagnetic interference (EMI) can both affect and be transmitted by mega-watt wind turbines. This paper provides a general overview on EMI with respect to mega-watt wind turbines. Possibilities of measuring all types of electromagnetic interference are shown. Electromagnetic fields resulting from a GSM transmitter mounted on a mega-watt wind turbine will be analyzed in detail. This cellular system operates as a real-time communication link. The method-of-moments is used to analytically describe the electro-magnetic fields. The electromagnetic interference will be analyzed under the given boundary condition with a commercial simulation tool. Different transmitter positions are judged on the basis of their radiation patterns. The principal EMI mechanisms are described and taken into consideration.

EE 364B: Wind Farm Layout Optimization via Sequential Convex Programming
In a wind farm, the wakes formed by upstream wind turbines decrease the power outputs of downstream wind turbines by reducing wind speed. This wake interference significantly lowers the power production of a wind farm, especially that of a large-scale wind farm. In this paper, we express wind farm power as a differentiable function of location variables. We then apply a sequential convex progra...
متن کاملGuiding Wind Farm Optimization with Machine Learning
Wind farm micro-siting is a complex process that requires multidisciplinary analysis and optimization. The problem consists not only of positioning the wind turbines in the locations within the site that have the most wind energy potential, but also it has to minimize wake interference between turbines. This means that usually the sum of the expected isolated turbines is less than the actual pe...
