Development of Wind Turbine Simulators Using PSCAD
نویسنده
چکیده
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 considered is designed to show the effects of the tower shadow effect and blades asymmetry. Torsional oscillation effect on the drive train is also considered. A pitch angle controller is used to limit the turbine output power to the rated value to protect the coupled generator. Simulation results are presented to verify the wind turbine simulator performance.

Effect of Different Turbine-generator Shaft Models on the Subsynchronous Resonance Phenomenon in the Double Cage Induction Generator Based Wind Farm
This paper focuses on the turbine-generator shaft models of double-cage Induction Generator (IG) based wind farm and its influence on the sub-synchronous resonance phenomenon. For this purpose, six different shaft models as 6-mass, 4-mass, 3-mass I, 3-mass II, 2-mass and 1-mass models are considered for double-cage IG wind-turbine. By using the linear modal analysis method, the effects of the d...
متن کاملRobust Control Examples Applied to a Wind Turbine Simulated Model
Wind turbine plants are complex dynamic and uncertain processes driven by stochastic inputs and disturbances, as well as different loads represented by gyroscopic, centrifugal, and gravitational forces. Moreover, as their aerodynamic models are nonlinear, both modelling and control become challenging problems. On one hand, high–fidelity simulators should contain different parameters and variabl...
