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 کاملDifferent Types of Pitch Angle Control Strategies Used in Wind Turbine System Applications
The most common controller in wind turbine is the blade pitch angle control in order to get the desired power. Controlling the pitch angle in wind turbines has a direct impact on the dynamic performance of the machine and fluctuations in the power systems. Due to constant changes in wind speed, the wind turbines are of nonlinear and multivariate system. The design of a controller that can ad...
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 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 کاملWind Turbine Control Using PI Pitch Angle Controller
This paper suggests two methods to calculate the gains of a proportional-Integral pitch angle controller for a 5 MW wind turbine. The first method is analytical and the second one is based on simulation. Firstly, the power coefficient characteristics for different pitch angles are calculated. Secondly, the output powers vs. rotor speed curves from cut-in to cut-out wind speeds are simulated. Th...
