An analytical method of calculating an optimal resistance for crowbar of doubly fed induction generator (DFIG) under single phase fault is proposed by taking into account the impact of crowbar on reactive power, rotor current, voltage and electrical torque respectively. Finding the optimal resistance value for the crowbar is based on Analytic Hierarchy Process (AHP) in this paper, of the DFIG during...
Nowadays doubly fed induction generators (DFIG) are the most popular generator used in wind turbine plants because of their cost effective partly rated power converter and variable speeds. The main drawback of DFIG is their sensitivity to gird perturbation especially voltage dips since the stator is directly connected to the grid. Rapidly increasing contribution of wind energy in power generation...
