In the case of doubly fed induction generator (DFIG), power electronics converter effectively decouples the inertia of the wind turbine generator from the power system. Hence, the increased penetration of DFIG results in higher frequency excursion and increased rate of change of frequency in the event of generation loss or increased load demand. This paper presents the added feature of frequency regulation...
The operational behaviour of a Remote Area Power Supply (RAPS) system consisting of a Doubly Fed Induction Generator (DFIG) as the wind turbine generator, diesel generator system, battery storage, dump load and mains loads is investigated in this paper. The diesel generator operates during low wind penetration or high load demand periods. Otherwise, the DFIG and battery storage are able to satisfy...
Doubly fed induction generators (DFIGs) are widely used in wind generation. The possibility of getting a constant frequency AC output from a DFIG while driven by a variable speed prime mover improves the efficacy of energy harvest from wind. In the power lab at North Dakota State University (NDSU), the wind turbine is substituted by a variable-speed DC motor which dives a DFIG. A wound rotor induction...
