This paper represents the modeling and simulation of 2 MW Direct Drive PMSG Wind energy

conversion system (WECS). The modelling of wind turbine and PMSG is carried out in simulink to determine its

parameter. WECS consists different components namely Wind turbine, Generator, rectifier-inverter, controller

system including transformer, grid etc. The PMSG and converter model are established in the d-q model.

Keywords: PMSG, WECS, Wind turbine, rectifier, inverter, MATLAB/SIMLINK, transformer, Grid
