This paper presents power quality issues of a grid connected wind generation system with a MW-class direct-driven permanent magnet synchronous generator (PMSG). A variable speed wind turbine model was simulated and developed with the simulation tool of PSCAD/EMTDC. The model includes a wind turbine with one mass-model drive train model, a PMSG model and a full-scale voltage source back to back PWM...
Paper confers a newfangled empirical model to figure, flicker, instigated in the horizontal axis, upwind turbine, due to vertical wind shear, in continuous operation. Postulations, boundary curbs and limitations of the model are also depicted. In the proposed model, vertical wind shear, number of blades, blade length and tower height are echoed. The elegance of the model is that, it is expedient to...
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...
In order to fully study the electrical, mechanical, and aerodynamic aspects of a wind turbine with a doubly fed induction generator, a detailed model that considers all these aspects must be used. A drawback of many works in the area of wind turbine simulation is that either a very simple mechanical model is used with a detailed electrical model, or vice versa. Hence, the effects of interactions between...
