Abstract

Increasingly, variable speed regulated wind turbine control systems are being required to alleviate structural loads. In standard approaches to alleviating tower loads, coupling of the generator speed and tower speed control causes reduced effectiveness of not only the tower speed loop itself but also the generator speed loop. Using improved representation of the wind turbine dynamics and catering specifically for the interaction of the two loops, a new configuration of control system, for a variable speed pitch regulated wind turbine is derived that, by most performance measurements, out-performs standard controllers.
