Wind velocity and position sensorless operation for PMSG wind generator

In order to perform an efficient operation of a wind generation system, it is necessary to drive a windmill at an optimal rotor speed. For that purpose, a rotor position and wind velocity sensor become indispensable. However, these equipments are required to remove from wind generation system due to cost reduction and reliability enhancement. In this paper, wind velocity and position sensorless operating method of wind generation system using the full-order observer is proposed.
