With the increasing share of wind in power generation, the dynamic behavior of the power system will change considerably due to different technologies used for wind and conventional generators. This paper will describe the sustainability of Doubly-Fed Induction Generator during the abnormal condition on grid also during the fault condition. For the selection of the suitable ratings of crowbar (chopper resistors) approximations are to be carried out. For simulation studies taking wind speed variations into account, or when the rotor shaft speed deviation becomes significant, the turbine's speed and its pitch control systems have to be considered. The short -circuit current contribution of DFIG has received much attention. Wind turbines with a doubly fed induction generator have a crowbar to protect the power electronic converter that is connected to the rotor windings of the induction generator. A Grid fault ride through capability of Doubly Fed Induction Generator in Wind Energy Transfer System is determined using PSCAD / EMTDC Software Simulation. DFIG Rotor side converter is very much sensitive to Grid Fault. A single line to ground fault at grid is taken for study. Voltage dip occurs on stator voltage and current rises instantaneously, with this rotor side current increased which will result in damage of rotor side converter. |
