Abstract

This paper presents a novel method for synchronization of DFIG based wind turbine generation system with the grid. The proposed method is based on direct power control (DPC) taking two new variables, called virtual active power and virtual reactive power into account. By means of virtual power control over its reference value determined in such a way that the stator induced voltage exactly follows the grid voltage synchronization conditions are realized. Using this method, generator doesn´t face any mechanical or electrical stress when connected to the grid. Simulations have been carried out by MATLAB-Simulink for a 2MW DFIG to show the effectiveness of proposed method for Synchronization of wind turbine without any electrical stress.
