The relevance of a wind turbine’s control system has steadily been increasing over the last 20 years. Due to the constant demand for reduced LCOE, the rated power of wind turbines was extended by increasing mainly the hub height and the rotor diameter. This increase in size makes the turbine components softer and more susceptible to fatigue. Consequently, the objectives of turbine control have  considerably evolved from simply maximizing energy yield into a wide spectrum of competing goals.

 

This presentation gives an introduction to the mechatronic modelling of wind turbines. Such models can be used in a subsequent step to design and parameterize the control system, which is demonstrated at a typical pitch-speed-control loop. At the end, an outlook on future advanced control solutions is given.
