Modelling and control of 6mg siemens wind turbine blades angle and rotor speed

Abstract

In this article, dynamic modelling of governed on various parts of the Siemens SWT- 6.0 6 MW wind turbine, for critical work point, rotor output speed operation, and bade step angle in the presence of tracking aim various profiles with oscillation and constant speed profile are investigated. Also, the classic controller with frequency instability impact elimination time filter of synchronous generator against wind immediate changes to the model has been used. Choosing classic controller coefficients causes both turbine rotor speeds control to reduce rotor speed excessive effect in low frequency and to converge with control aim signal and output frequency regulation in PMSG generator also provides necessary changes for blade step angle in authorized and unauthorized wind various speeds for pitch driver. Simulation results show fairly accurate control of rotor speed output behaviour and necessary changes to drive blade step angle with a small percentage of RMS fault and mean squared error of plant output signals for model uncertainty.
