Abstract

A turbine control system for a variable speed electrical generator in a wind turbine mounted atop a support tower. The wind turbine converts wind energy into a driving torque applied to the generator. The control system includes tachometers providing rotation rate directly, angle encoders providing the rotation angular position of the shaft, or incremental angle encoders indicating when the shaft angle has changed by a discrete amount. The wind speed is determined using rotation rate and its derivative as determined by differentiating the rotor angular position measurements independently of torques and turbine models. A further innovation is the use of a rotation rate estimator to produce the rotation rate and its derivative based on the pulse count data produced by incremental rotor angle encoder common in turbines. The estimator is designed to provide an estimation bandwidth consistent with good control while also eliminating undesired frequencies. A further innovation is the use of the wind estimate to calculate the power-optimum pitch, torque, power and rotor rotation rate operating points. A further innovation is the use of the optimum operating points as set points in a control system providing the turbine with maximum power generation in turbulent winds.
