This paper proposes a VAR regulation strategy when voltage of monitor bus fluctuates or drops severely. If voltage of monitor bus fluctuates and the CrowBar does not response, rotor side converter will change VAR output of DFIG by regulation strategy while the converter of grid side can only keep DC voltage stability. When severe grid fault occurs and CrowBar acts, rotor side converter is out of control...
This paper proposed a novel layered VAR control strategy to solve VAR and voltage stability caused by wind farm integration. The strategy first calculated reactive power demand of the wind farm by deviation of reference voltage and measured voltage of control point. Then the calculated reactive power demand was distributed by equal power factor algorithm to single wind generator in the wind farm....
Details of control and instrumentation for on-grid and off-grid operation of a small induction generator based wind turbine are presented in this paper. A micro-controller based system controller is used to connect/disconnect the wind power generator to the grid, and also to maintain the grid connection. Several real time situations are considered during the operation of the wind power generation...
The paper is aimed at presenting the dynamic behaviour of a wind turbine equipped with a doubly fed induction generator (DFIG) in case of disturbances in the interconnected grid. A model of a DFIG is presented and adapted for analyzing the response of the wind generator to voltage control, frequency control, voltage sags and wind variations. Simulations, performed by a widely used power system analysis...
