Wind turbine with blade pitch control to compensate for wind shear and wind misalignment |
摘要 |
A wind turbine rotor load control. The pitch of the blades is controlled in a conventional manner by a command component, a rotor blade pitch command signal. A storage contains stored values of a set of moments for various wind speeds. A moment sensor provides a moment signal output. An instantaneous wind speed indicator provides an instantaneous wind speed value output. A conversion logic connected to the moment signal and to the instantaneous wind speed value, provides a calculated pitch modulation command. Combining logic connected to the calculated blade pitch modulation command and to the collective pitch command, provides a combined blade pitch command, which includes compensation for instantaneous moment deviations of the wind turbine. |
