The generator-side converter control aims to achieve maximum wind energy tracking and maintain stable operation despite changes in wind speed.In this paper

by establishing a wind turbine model and a mathematical model of the permanent magnet direct-drive(PMDD)synchronous generator

a theoretical comparative analysis of two generator-side converter control strategies

namely the zero d-axis control method and the unity power factor control method

is conducted.Moreover

simulation verification of the two control strategies under constant and varying wind speed conditions is performed using a simulation system.The conclusion is drawn that the unity power factor control method makes it easier for the wind turbine to maintain stable operation under overspeed conditions.
