Abstract

This paper presents a new power smooth control scheme to enable Double Fed Induction Generator (DFIG) based wind turbine system to safely and smoothly ride through the extreme operating gusts. Under the normal condition, the control scheme will have few impacts on the maximum power point tracking control of DFIG. In the event of extreme operating gust, the new scheme controls the electromagnetic torque directly so that the generated power can be effectively limited and smoothed. Consequently, the negative impacts on grid and turbine itself can be reduced. The scheme involves a detection module which can detect the extreme operating gust and activate the power smooth control as quickly as possible. When the gust terminates, the control scheme can ensure smooth transition back to normal control. The simulation results verify the effectiveness of the proposed scheme.
