عنوان انگلیسی: Reactive Power Control Strategy of DFIG Wind Farms for Regulating Voltage of Power Grid دانلود رایگان اصل مقاله انگلیسی ناشر:PES General Meeting | Conference & Exposition, 2014 IEEE تعداد صفحات انگلیسی: پی دی اف5 تعداد صفحات فارسی:ورد 21 Abstract If a wind farm is weakly connected to a power grid, then the voltage of the connection point fluctuates frequently due to the changeable wind speed. The active and reactive power of a doubly-fed induction generator (DFIG) can be decoupling controlled and the grid-side converter (GSC) of a DFIG can also generate some reactive power by adjusting the power factor, thus a DFIG can be considered as a reactive power resource to stabilize the voltage of the connection bus. Based on the power relationship of a DFIG, the up and down reactive power limitations of DFIG stator and GSC are analyzed. Then a reactive power control strategy of a DFIG wind farm is proposed, in which, a certain number of DFIGs are selected to suppo ...
