“…The total power that is available to a wind is given as P=1/2 ρ AV 3 where ρ is the air density in Kg/m 3 , A is the exposed area in m 2 , and V is the wind velocity in m/sec. The density is a function of pressure, temperature and relative humidity.…”

“…Large wind turbines with the wind power of MW levels are becoming more and more attractive to offshore wind firm, and a number of wind firms of rated capacity of hundreds of MW level are going to be connected to the existing power system in near future. Due to its simple construction and low maintenance cost, wind turbines based on induction generators are mostly used [2].…”

Abstract-Wind is merely air in motion. Wind turbine convert kinetic energy from the wind that passes over the rotors into electricity. In this paper a wind electrical system is designed using induction generator in PSCAD (Power System Computer Aided Design) software. Here a simulation approach is adopted to observe the nature of power obtained from the wind turbine. From the study it is seen that the turbine power is dependent on air density, area of the rotor and wind speed Index Terms-Air density, rotor area, wind electrical system, wind speed, wind turbine power.

“…With the increase in size of the wind turbines, one question arises whether long flexible blades have an important impact on the transient stability analysis of wind energy systems during a fault (Li & Chen, 2007). One way to determine the dynamic properties of the blades is through the use of finite element methods, but this approach cannot be straightforwardly accommodated in the context of studies of power system analysis.…”

“…However, the rotor of modern wind turbine is large and long and cannot be simply considered as a rigid body. In the study of electrical transient performance, it is also important to consider the turbine rotor dynamics [14]- [15]. The reason is that the blade edgewise symmetrical mode couples directly to the drive train so if this mode is excited it will also lead to the torsional vibration.…”

Abstract. Torsional vibrations in the drive train of the doubly-fed induction generator (DFIG) based wind turbine can cause large mechanical stress and reduce the life cycle of the components. They can be easily induced by sudden changes from the turbine rotor side or grid side. In this paper, a model-based active damper of the torsional vibration designed with the linearquadratic-Gaussian (LQG) algorithm is proposed. The modelling of the drive train takes the flexibility of the rotor blades into account and utilizes a three-mass model. A combination of different simulation packages, namely FAST (Fatigue, Aerodynamics, Structure, Turbulence) and Matlab/Simulink describing important dynamics of both the mechanical and electrical side, is applied to analyse the vibrations in the drive train and test the algorithm. Simulation results show that the proposed active damping can suppress the torsional vibrations in the drive train effectively even if a gird fault occurs.
