IMPLEMENTATION OF LOW VOLTAGE RIDE- THROUGH PROTECTION TECHNIQUES FOR DFIG WIND GENERATOR
Keywords:
DFIG, LVRT, DC Chopper, Crowbar, SDR(series dynamic resistance)Abstract
The Low-Voltage Ride-Through (LVRT) highlights for wind turbines is that they can stay on the
web and backing the electric network when fault events happens rather than immediate tripping. With
expanding entrance of wind turbines during and after a short-term fault in the grid, the network association
codes in many nations it is significant that they ought to stay associated with keep up dependability likewise, for
wind turbine it is also important to remain the system stable during and after the fault clearance The DFIG has
the upsides of; minimal effort, low weight, and high effectiveness, and one of its fundamental disservices is its
affectability to the voltage plunges. Two LVRT techniques for insurance of DFIG during low voltage occasions
are looked at. The two methods which are used are Crowbar and series dynamic breaking resistor. These
techniques were tried under various sorts of deficiency including balanced and unsymmetrical issues and their
exhibitions are thought about. As given above utilizing the Matlab/Simulink quantities of assurance procedures
of the DFIG areexamined beneath and reenacted under various conditions.
