    摘要: A method of controlling the load of a wind turbine is provided. A rate of wear experienced by the wind turbine as a result of the current operating conditions of the wind turbine is determined. A control vector for controlling the wind turbine is determined based on the determined rate of wear. The load of the wind turbine is controlled in accordance with the determined control vector. Determining the control vector includes weighting the determined rate of wear by a cost of electricity value and determining the control vector based on the weighted rate of wear.

    摘要: An arrangement to measure deflection of a blade of a wind turbine is provided. A transmitter is arranged close to the tip end of the blade, while a receiver is arranged close to the root end of the blade. The transmitter and receiver are prepared for a wireless transfer of a monitoring signal, which is sent from the transmitter to the receiver. A monitoring system is arranged close to the root end of the blade. The monitoring system is adapted to generate the monitoring signal. The monitoring system is connected with the transmitter by a cable-bound communication line, thus the monitoring signal is transferred from the monitoring system to the transmitter. The monitoring system is connected with the receiver, thus the monitoring signal is transferred from the receiver to the monitoring system. The monitoring system is adapted to determine the deflection of the blade based on the transferred monitoring signal.
