Environmental effect of large wind turbines
Because a wind turbine blade reflects electromagnetic radiation, it can produce ghost images and jitter on television. From simulation experiments using different strengths and time delays of the secondary signals relative to the primary signal at the receiver, a criterion has been established for interference that is unacceptable for extended periods of viewing. For a given TV transmission and given wind turbine, the interference zone can be computed by considering the propagation conditions. Small wind turbines of a few kilowatts capacity are found to produce interference with zones extending only a few tens of feet. The effect of a large wind turbine on other electromagnetic systems has been investigated, including aircraft navigational radars and Loran-C, which are relatively insensitive to interference. (LEW)
