DFIG in a Wind Farm

Authors(1) :-Dr. Deepak P. Kadam

Considering the rate at which conventional sources are being consumed and their impact on environments it is necessary to adopt alternate energy technologies for sustainable development. Out of various renewable energy sources, wind generation is most cost effective in addition to its various advantages. Worldwide the share of wind generation connected to grid is increasing at faster rate and in near future will become one of the major sources of renewable energy. With rapid development of wind power technologies and significant growth of wind power capacity installed worldwide, various wind turbine concepts have been developed. The major concerns and issues highlighted in grid code are active, reactive power control and power quality. In India the majority of wind farms are in rural area. Increasing size of wind farm connected to grid will lead to various challenges such as power quality, security and reactive power control during normal operation, and fault ride through capability during fault conditions. 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 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 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 occur on stator voltage and current rises instantaneously, with this rotor side current increased which will result in damage of rotor side converter.
