Pitch regulation of a wind turbine; Pitchregulering af en vindmoelle

Abstract

In the near future, large wind turbines ranging from 1 MW to 1.5 MW will be the standard. These large wind turbines will be very expensive and it is therefore very important to guarantee long durability and good reliability of the plant. This report deals with dynamic modelling and control of a large wind turbine. First a nonlinear model of the wind turbine is presented. A stochastic model for the wind is also introduced. The nonlinear model is then implemented as a modular simulation model. A linearized version of the model is used for control design. The control design includes design of a gain scheduled stochastic pole placement controller. To optimize produced electrical energy at low wind velocities, different optimization methods are discussed. Finally transition between optimization and limitation of produced electrical power is examined. Controllers and optimizations methods are evaluated on the simulation model. (au) (16 refs.)
