In-Depth Information
the main windows of the SCADA system, with real-time data collected by the
sensors of the four wind turbines: voltages, currents, rotor speeds, powers, torques,
pitch angles and yaw angles.
14.2.4 Smart Micro Grid
An electrical smart micro grid with variable load is connected to the generators of
the four wind turbines at the output of the farm. The micro grid is composed of a
set of batteries for energy storage, variable electrical loads, solar panels as addi-
tional renewable generators and switches to create different grid topologies (see
Fig.
14.9
).
14.2.5 Wind Source Equipment
A group of three fans creates the wind profile, with variable speed, direction and
frequency of variation (see Fig.
14.1
). The two largest fans are used to generate the
main wind flow and the smallest one to create wind disturbances and turbulences
in speed and direction.
