摘要： A method of operating an electrical heating element of a wind turbine rotor blade, the method comprising the following steps:
• Applying a voltage to the heating element,
• Measuring a current flowing through the heating element,
• Measuring the voltage applied to the heating element,
• Calculating a reference current by applying a normalization factor to the measured current, wherein the normalization factor corresponds to the ratio of a nominal voltage to the measured voltage,
• Triggering an action when the reference current is outside a first predetermined reference current range.

摘要： The present invention relates to a method of operating a wind turbine, a method of manufacturing a wind turbine and a wind turbine. The wind turbine comprises a permanent magnet (PM) synchronous generator, a main converter, a main converter controller, a wind turbine master controller and an electrical power supply stage comprising an electrical energy storing device. A startup of the wind turbine can be performed using electrical energy from the electrical energy storing device independent from a power supplying grid and/or a combustion engine. After startup, the wind turbine can be operated in an island mode by controlling the intermediate voltage of the main converter by the main converter controller and retrieving power from the PM synchronous generator independent from the electrical energy storing device.

摘要： An example method may include determining a drag force of an apparent wind on an aircraft that is coupled to a ground station via a tether. The method also includes determining a trajectory of the aircraft to a point downwind of the ground station such that the aircraft travelling the trajectory causes the tether to unfurl along a catenary path above ground. The method further includes determining an orientation of the aircraft to travel the trajectory in the apparent wind so that an actuator of the aircraft is configured to provide a vertical thrust in a direction substantially perpendicular to the ground. The method also includes determining a vertical thrust for the aircraft at the orientation to travel the trajectory in the apparent wind. The method also includes providing instructions to cause the actuator of the aircraft to provide the vertical thrust to move the aircraft along the trajectory.

摘要： Determination of distance and/or position relative to one or more points by transmission of a wideband signal by a first antenna, reception of the transmitted wideband signal by a second antenna and comparison of the time delay between the transmitted and received signals. The first and second antennas are connected to a timer/processor unit. One or more of the first or second antennas is movable to an unknown position to be measured, but maintains connection to the timer/processor through a fixed or known delay communication link. The timer/processor contains a time base for generating the transmitted signal and an offset timer for measuring the time delay of the received signal. The received signal may be processed to determine a start time or leading edge that may resolve RF cycle and modulation bandwidth ambiguities and may allow positive determination of distance much shorter than a wavelength at the operation center frequency.

摘要： The layout and configuration of wind turbines in a wind power plant includes identifying constraints of a power plant site (400) and defining at least one region in the site for placement of a plurality of wind turbines (450). The wind state at the region in the site is determined (500). An actual wind condition at the various possible wind turbine locations within the site is determined (600) by modeling the wind state with wake effects (550) at the respective wind turbine locations, the wake effects resulting from cumulative placement of other wind turbines at various locations in the region. Individual wind turbine configuration and location within the region is then selected (650) as a function of the actual wind conditions that each of the individual wind turbine locations to optimize power output of the individual wind turbines. The selection of turbine configuration includes selection of a turbine hub height that minimizes wake loss of the individual wind turbines as a function of the actual wind conditions predicted for the turbine location.
