modelPartialWindTurbine
Extends from Buildings.Electrical.Interfaces.PartialWindTurbineBase (Base class for turbine model that contains basic parameters).
Information
Model of a wind turbine whose power is computed as a function of wind-speed as defined in a table.
Input to the model is the local wind speed.
The model requires the specification of a table that maps wind speed in meters per second to generated
power Pt in Watts.
The model has a parameter called scale with a default value of one
that can be used to scale the power generated by the wind turbine.
The generated electrical power is
P = Pt scale
For example, the following specification (with default scale=1) of a wind turbine
WindTurbine_Table tur(
table=[3.5, 0;
5.5, 100;
12, 900;
14, 1000;
25, 1000]) "Wind turbine";
yields the performance shown below. In this example, the cut-in wind speed is 3.5 meters per second, and the cut-out wind speed is 25 meters per second, as entered by the first and last entry of the wind speed column. Below and above these wind speeds, the generated power is zero.
