Abstract

The present invention is directed to a wind turbine including a tower (1) and a tower deflection detection device. The tower deflection detection device comprises a transmitter (2) configured to transmit a first electromagnetic signal (100); a leaky feeder (3) having a plurality of apertures; a receiver (4) connected to the first leaky feeder (3) and configured to receive a second electromagnetic signal (200) from the first leaky feeder (3), the second electromagnetic signal (200) is a signal reflected from a reflection portion of the tower (1), when the first electromagnetic signal (100) impinges the reflection portion of the tower (1), and entered into the leaky feeder (3) through at least one of the plurality of apertures; and a processing unit connected to the receiver (4) and configured to receive the second electromagnetic signal (200) from the receiver (4), to analyse the received second electromagnetic signal (200) and to determine a deflection amount of the tower (1) based on the analysed second electromagnetic signal (200).
