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 کاملSpeed Control of Wind Turbine through Pitch Control Using Different Control Techniques
Pitch control is one of t he major aspects of wind turbine control, particularly over high wi nd s p e e d a n d oscillations. General El e c t r i c (GE) model of wi n d t ur bi ne i s practically compatible with the structure of the wind turbines. I t h a s b e e n p r o v e d t h a t simulation results using this model are closer to the actual case, compared to other available mod...
متن کاملWind Turbine Synchronous Reset Pitch Control
Reset controllers are commonly used to smooth the transient response of systems. We use this technique to improve a standard baseline pitch controller for offshore wind turbines (WTs). The introduction of this strategy enhances the overall performance of the WT. In particular, the fore-aft and side-to-side accelerations of the WT tower are significantly reduced, whilst a steadier power output i...
متن کاملSubspace Predictive Repetitive Control with Lifted Domain Identification for Wind Turbine Individual Pitch Control ⋆
Individual pitch control (IPC) is gaining increasing acceptance as a method for mitigation of periodic disturbances in wind turbines. This paper aims at formulating a repetitive control (RC) methodology capable of adapting online to changing turbine dynamics. This is achieved by performing system identification in a reduced-dimensional space using basis functions and using the identified parame...
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...
