Abstract: |
With more and more wind power generation
integrated into power grids to replace the conventional
turbine-generator (T-G) units, how the subsynchronous
resonance (SSR) of conventional T-G units is affected
becomes an important technical issue. In this paper, a
group of T-G units are interconnected with a series compensated
transmission line, and some units are substituted
by a nearby DFIG-based wind farm (WF). Under such
circumstances, the SSR of power systems would change
accordingly. This paper establishes the mathematical
model to analyze the torsional interaction (TI) and the
induction generator effect of the T-G units. Both eigenvalue
analysis and time domain simulations demonstrate
the impact of DFIG-based WF on SSR of power systems
and how the control parameters of wind farms can affect
the SSR. |
