Spawners¶

Base class spawners for wind turbine aeroelastic simulations within spawn

class spawnwind.spawners.AeroelasticSimulationSpawner[source]¶

Spawner of aeroelastic simulations of wind turbines including dependent turbulent wind file creation when necessary

blade_final_pitch¶: Pitch angle in degrees at which one particular blade finishes after a pitch manoeuvre

blade_initial_pitch¶: Pitch angle for single blades at start of simulation; in degrees, positive towards feather

blade_pitch_manoeuvre_time¶: Time in seconds at which one particular blade starts a pitch manoeuvre

final_pitch¶: Pitch angle in degrees at which all blades finish after a pitch manoeuvre

final_yaw¶: Yaw angle in degrees at which the blade finishes after a yaw manoeuvre

grid_loss_time¶: Sets time in seconds for grid loss (zero generator torque) to occur

initial_azimuth¶: Rotor azimuth of blade 1 at start of simulation in degrees

initial_pitch¶: Pitch angle for all blades at start of simulation; in degrees, positive towards feather

initial_rotor_speed¶: Rotor speed at start of simulation in rpm

initial_yaw¶: Nacelle yaw angle at start of simulation in degrees; clockwise from North

operation_mode¶: Operation mode: ‘normal’ - power production run with generator on and rotor free ‘idling’ - generator off but rotor free ‘parked’ - generator off and rotor fixed

output_start_time¶: Simulation time that elapses before the simulator starts logging results
