Wind turbine generator movement model

How is a wind turbine rotor modeled?

In power system dynamic simulations, the wind turbine rotor is represented by a simplified model derived from the disk actuator theory, and the drive train is commonly modeled by the two-mass model.

How do wind turbines influence power system dynamics?

Because of the increasing wind power penetration on power systems and the rapid development of the wind turbine technology, the wind turbines and wind farms begin to influence power system. This justifies the development of adequate models to represent the behaviour of wind turbines in large power system dynamic simulations.

What is a wind turbine dynamic model?

While there are many wind turbine dynamic models available in the literature [19, 36–39], the focus is largely on modeling variable-speed wind turbines. These models often oversimplify the mechanical drive train and aerodynamics, since the aim is to evaluate power and rotor speed control mechanisms.

How a wind turbine is controlled by a power controller?

The power is controlled by the power controller to increase with a generator slip of 2 % as shown in Fig. 20. Power limitation strategy: When the wind is high enough to produce the rated power, the power of the wind turbine is controlled to the rated power.

How does a wind turbine turn mechanical power into electricity?

This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity. A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.

What is the RST model for wind turbine aero-dynamics and power output?

The rst model for understanding wind turbine aero-dynamics and power output were formulated by Rankine and Froude [13{15] in their studies of propeller thrust dynamics.
