Abstract :
Electromagnetic fields resulting from a GSM transmitter mounted on a large wind turbine will be analyzed. This cellular system operates as novel communication backup in case the standard communication between operator and hub control systems is interrupted. The method-of-moments is used to analytically describe the electro-magnetic fields caused by a GSM 900 MHz transmitter mounted on the hub of a wind turbine. Using a commercial simulation tool the electromagnetic field distribution will be analyzed to determine an optimized wireless communication link to a base station. Different transmitter positions are evaluated based on their radiation patterns. Scattering and diffraction by the turbine´s rotation is taken into account.
