Modelling and control of PMSG based offshore wind turbine

Abstract

The aim of this project is to model a wind turbine driven by permanent magnetic synchronous generator (PMSG) and to design the control of the WT able to support and recover from voltage sags. Moreover, this project demonstrates the efficiency and the effects of a voltage sag on the grid stability and the ro- bustness of the voltage source converter (VSC) as converter in the WT world. The generator side inverter, adjusts the synchronous generator and decouples it from the grid when necessary, for example when the voltage sags occurs. On the other hand, the grid-side inverter oversees the power flow between the DC bus and the AC side. Moreover the fault-ride through capability has the capability to recover fast after a fault clearance. The simulation results in Matlab Simulink 2021b shows that the model has good dynamics and it recovers with a short time after a voltage drop, stabilizing the turbine.
