A hybrid drive wind turbine equipped with a speed regulating differential mechanism can generate electricity at the grid frequency by an electrically excited synchronous generator without requiring fully or partially rated converters. This has extensively been studied in recent years. To enhance transient operation performance and low-voltage ride-through capacity of proposed turbine, we aim to...
Description: This tele-seminar series gives the results from a PSERC project (Executive Summary | Full Report) that examined the impact of increased penetration of doubly-fed induction generator (DFIG) wind generation on power system dynamic performance and hence reliability. DFIG wind turbines use controls that effectively isolate the inertia from the grid. In addition, large wind farms are ty...
This paper have studied the dynamic of a 2.0 MW Doubly Fed Induction Generator (DFIG) during a severe voltage sag. Using the dynamic model of a DFIG, it was possible to determine the current, Electromagnetic Force and flux behavior during three-phase symmetrical voltage dip. Among the technologies of wind turbines the DFIG is widely employed; however, this machine is extremely susceptible to di...
