Abstract
An object of the present invention is to provide a wind turbine generator in which a communication channel can be added in communication between a hub and a nacelle, without making a modification to the design of a slip ring. The present invention provides a wind turbine generator in which communication between the hub and the nacelle is performed by superimposing an information signal onto AC power carried over an AC power line between the hub and the nacelle via the slip ring.
