Maximizing turbine up-time and reducing maintenance costs are key technology drivers for wind turbine operators. Components within wind turbines are subject to considerable stresses due to unpredictable environmental conditions resulting from rapidly changing local dynamics. In that context, systems health management has the aim to assess the state-of-health of components within a wind turbine,...

In this paper, a wind turbine simulator is developed using PSCAD. The wind turbine static characteristics are modeled using the relation among the turbine power, the wind speed, and the blade pitch angle. Also, the dynamic characteristics of the wind turbine are modeled through a two-mass oscillating system, representing the turbine and the generator connected by elastic shaft. The system consi...

In this study, an unsteady aerodynamic simulation is performed to realize the influences of platform surge motion on the aerodynamic performance of a high capacity offshore floating wind turbine. A dynamic model with pitch angle control system is utilized to propose a more realistic model of wind turbine and also achieve the rated condition of the rotor. The transient effect of platform surge m...

A data-driven approach for maximization of the power produced by wind turbines is presented. The power optimization objective is accomplished by computing optimal control settings of wind turbines using data mining and evolutionary strategy algorithms. Data mining algorithms identify a functional mapping between the power output and controllable and non-controllable variables of a wind turbine....

The problem of robust control of a wind turbine is considered in this paper. A set of controllers are designed based on a 2 degrees of freedom linearized model of a wind turbine. An extended Kalman filter is used to estimate effective wind speed and the estimated wind speed is used to find the operating point of the wind turbine. Due to imprecise wind speed estimation, uncertainty in the obtain...

the shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. in reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a s-shape profile. the pr...

More cost-effective wind turbines with higher rated power, are desired to emerge in the near future. The current trend in wind energy is for this reason the increase of the wind turbine dimensions. Increasing their size is however strongly limited by the rotor blades structural integrity towards occurring aeroelastic loads, especially with respect to blade fatigue. Advanced (re)active load redu...

To enable wind turbines to produce power under great variety of wind conditions a sophisticated control system is needed. Wind turbine system is highly nonlinear and its dynamic changes rapidly with the change of wind speed. Besides this, wind turbine mechanical structure is very flexible due to its great height and tends to oscillate. All this makes the design of wind turbine control system ve...

In this study, the feasibility of using micro-wind turbines to power wireless sensors on a cable-stayed bridge is comprehensively investigated. To this end, the wind environment around a bridge onto which a turbine is installed is examined, as is the power consumption of a wireless sensor. Feasible alternators and rotors are then carefully selected to make an effective small wind generator (kno...

Wind is one of the cheapest and widely source of alternative energy. To convert it into electrical energy a wind turbine with generator is used but to properly convert this wind energy into electrical energy proper design of wind turbine is needed. In this paper we presents a genetic algorithm based optimization technique for the estimation of wind turbine parameters on the basis of requirement...
