Control

GH Bladed includes a comprehensive model of the control system, allowing detailed modelling of power production control, supervisory control and safety system response, including the response to turbine faults

• Stall, pitch or aileron control

• Collective or independent pitch

• Fixed or variable speed

• Transducer dynamics

• Parked, idling, start-up, shutdown and power production simulations

• Built in PI controllers with gain scheduling, and supervisory control functions

• All turbine control functions can be fully user-defined through interface to MS Windows DLL

• Example controller DLL source code provided in FORTRAN, C and Visual Basic

• Comprehensive pitch actuator models

• Rotary and linear pitch drives

• Load-dependent pitch bearing friction

• Linearisation module generates state-space models for controller design
