Comparison of Individual Blade Control and Individual Pitch Control for Wind Turbine Load Reduction
The size of wind turbines has been growing fast in recent years with the largest now exceeding 7MW. Furthermore, this trend is expected to continue for the offshore sector. However, this increase in size is accompanied by an increase in the dynamic loading on the structure, in particular, unbalanced loads on the blade and hub. Apart from making wind turbine components more load tolerant, e.g. t...
متن کاملLoad Reduction on a Clipper Liberty Wind Turbine with Linear Parameter-Varying Individual Blade-Pitch Control
The increasing size of modern wind turbines also increases the structural loads caused by effects such as turbulence or asymmetries in the inflowing wind field. Consequently, the use of advanced control algorithms for active load reduction has become a relevant part of current wind turbine control systems. In this article, an individual blade-pitch control law is designed using multivariable li...
متن کاملIndividual Blade Pitch Control of a Floating Offshore Wind Turbine on a Tension Leg Platform
A disturbance accommodating controller (DAC) to reject wind speed perturbations is applied on a 5MW wind turbine mounted on a tension leg platform (TLP). Multi-blade coordinate (MBC) transformation is used to address the periodicity of the floating wind turbine system. A method to apply DAC after applying MBC transformation is developed and several implementation options are presented. Simulati...
متن کاملIndividual pitch control of wind turbines using local inflow measurements
This paper describes a model based control approach for individually adjusting the pitch of wind turbine blades and thereby attenuating the effect of asymmetric wind loads. It is assumed that measurements of local inflow along each blade are available. This effectively provides an estimate of the load distribution along the blades. The load estimates are used in a predictive setup where inflow ...
متن کاملFundamental Limitations of Preview for Wind Turbine Control
Wind turbine preview control has recently attracted attention in the literature. This is due to significant load attenuation and power optimization benefits that can be obtained by incorporating wind preview measurements into the turbine control laws. However, the trade-offs between performance, preview time, and actuation rate limits are not well understood. This paper investigates the fundame...
