PitchActuationLimited

https://bladednextgen.dnv.com/schema/0.4.1/Components/PitchSystem/PitchController/PitchSafetySystem/PitchActuationLimited.json

A safety system where the movement is limited by the available torque.

  • PitchSafetySystemType: string = ActuationLimited
  • AlwaysUseBackupPower: boolean
  • AppliedForceOrTorque: number (Nm)
  • SpringForceOrTorqueVsPosition: array[object (SpringForceOrTorqueVsPosition)]
  • DamperForceOrTorqueVsRate: array[object (DamperForceOrTorqueVsRate)]

A type of PitchSafetySystem

Properties

AlwaysUseBackupPower: boolean, optional

Backup power is normally only used in a grid loss. If true, this will trigger a switch to backup power torque limits in all safety system pitch action events.

default = False

PitchSafetySystemType: string

Defines the specific type of PitchSafetySystem model in use. For a ActuationLimited object, this must always be set to a value of ActuationLimited.

AppliedForceOrTorque: number (Nm)

The constant actuator torque (for a rotary system) or linear force (for a linear syste) applied during safety system pitch action.

default = 0

SpringForceOrTorqueVsPosition: array[ object (SpringForceOrTorqueVsPosition) ], optional

A look-up of the torque or force applied by a spring in the safety system at a given position.

DamperForceOrTorqueVsRate: array[ object (DamperForceOrTorqueVsRate) ], optional

A look-up of the torque or force applied by a damper in the safety system for a given rate.
