In the paper empirical model of flicker initiated in a wind turbine sited on a hill is established. Paper offers ins and outs of impact of various shapes of hills on vertical wind shear and consequently on the flicker produced in the wind turbine which is sited on that surface. In the model vertical wind shear, length of the turbine blade, tower height, slope of the hill are reverberated. The exquisiteness...
The electrical, mechanical, and aerodynamic aspects of a wind turbine (WT) need to be considered when examining the impact of the mechanical dynamics of a WT on the flicker level in a wind-diesel system. The paper describes how different software packages such as TurbSim, AeroDyn, and FAST can be used to model the aerodynamic and mechanical aspects of a WT, while Simulink can be used to model the...
This paper presents a simulation model based on support vector regression (SVR) for flicker estimation emitted from wind turbines. Training patterns are developed by applying the moving window method to estimate the voltage flicker. A comparison is done for the fixed speed wind turbine (WT), which leads to a conclusion that the SVR based flicker measurement is effective and not limited by processing...
To study the impact of aeroelastic aspects of a wind turbine (i.e. tower shadow, wind shear, turbulence, and mechanical vibrations) on the power quality of a wind-diesel system all electrical, mechanical and aerodynamic aspects of the wind turbine must be studied. Moreover, the contribution of the diesel-generator system and its controllers should be considered. This paper, describes how the aerodynamic...
