Constructing fast and representative analytical models of wind turbine main bearings

Probabilistic Models for Wind Turbine and Wind Farm Performance

A Markov model for the performance of wind turbines is developed that accounts for component reliability and the effect of wind speed and turbine capacity on component reliability. The model is calibrated to the observed performance of offshore turbines in the north of Europe, and uses wind records obtained from the coast of the state of Maine in the northeast United States in simulation. Simul...

Modeling and Control Analysis of Wind Turbine of Two Bladed and Three Bladed Wind Turbine Systems

The wind power industries arepresently the fastest raising renewable energy sector throughout the world compare to other sourses. the main aim of this paper is to develop the mathematical model and implemented in simulations for torque control of two bladed and three bladed wind turbine, by changing coefficient of power, tip speed ratio and pitch angle values for different wind speeds.To ensure...

Effect of Wind Speed and Load Correlation on ELCC of Wind Turbine Generator

Utilization of wind turbines as economic and green production units, poses new challenges to the power system planners, mainly due to the stochastic nature of the wind, adding a new source of uncertainty to the power system. Different types of distribution and correlation between this random variable and the system load makes conventional method inappropriate for modeling such a correlation. In...
