Abstract. Kω2 control, also called torque control, is a popular method for maximizing wind turbine power. For hydrostatic wind turbines, torque control becomes pressure control with pc = K′ω2 because pressure is proportional to torque. Inverse Kω2 control is an alternative approach using rotor speed control with ωc = (p/K′)1/2. This work analyzes the

6 FAQs about [Wind turbine wind farm simulation experiment]

How can a wind farm simulation be performed simultaneously?

The last two tasks can be achieved simultaneously using the concurrent-precursor method, where a simulation without wind turbines (precursor) is advanced in sync with the wind farm simulation (successor). The latter features a fringe region, where body forces are used to damp gravity wave reflections and to restore the desired turbulent inflow.

How to simulate wind farm wake flows?

The simulations use a high-fidelity solver called SOWFA, which is developed by NREL for the scale-resolving simulation of wind farm wake flows , . In this section, an example site with six turbines is investigated, which is illustrated in Fig. 2. The turbine type is the NREL 5MW and it has a diameter (denoted as D hereafter) of 126.4 m.

How can fast be used to model and analyze wind turbines?

FAST is very suitable to model and analyze wind turbines. A wind turbine is controlled by the electrical generator and its corresponding control. The impact of the control on its mechanical components can be observed because the modeled details of a wind turbine are represented in FAST.

Is geometry-resolving approach 6 feasible for wind farm simulations?

The geometry-resolving approach 6 requires a large number of grid nodes to resolve the boundary layer around the blade and the details of the complex turbine geometry, and for that, it is not feasible for wind farm simulations.

Is there an infinite wind farm simulation?

In this section, we run the same infinite wind farm simulation as has been conducted in Stevens et al. (2018), corresponding to the wind tunnel experiments performed by Chamorro and Porté-Agel (2011). The scaled wind farm consists of 30 wind turbines, arranged in an aligned configuration with 3 columns and 10 rows.

How are wind turbines parameterized?

The wind turbines are parameterized using the actuator line model. The complex terrain is represented by the curvilinear immersed boundary method. The predictive capability of the present method is evaluated by simulating two available wind tunnel experimental cases: the flow over a stand-alone turbine and an aligned wind turbine array.
