To follow a specific power curve for wind turbine application the following control must be activated
Input.Simu.type_control = 10;The nominal rotor speed (speed above which electrical power is maximum) is specified in
Input.Simu.N0=12Variable speed is activated with
Input.Simu.type_varspeed=1The wind speed is specified in (example of cut-out wind speed 15 m/s)
Input.Simu.V0spec=3:15;The associated rotor speed is specified in (example of a max rotor speed of 12 rpm)
Input.Simu.N0spec=[4 4 4.5 6 7.5 9 10 11 12 12 12 12 12];The corresponding power curve (aerodynamic power below nominal wind speed & electrical power above nominal wind speed) is input in W (it must be negative as MANATEE is in motor mode convention):
Input.Simu.Pspec=-[5 20 100 250 500 1000 1500 2500 3500 3500 3500 3500 3500]*1000;The default control maximizes the Iq current if the voltage limit is not reached. The maximum voltage is set in the simulation project with
Input.Simu.U0_LLmax=700; % maximum line to line RMS stator voltage [V]Negative Id current is used when the voltage limit is reached. The operating point is chosen to meet maximum voltage requirement while maximizing efficiency.
