Abstract:
The investigation and determination of the impact of DFIG
wind farms and their controllers on power system transient
performance require power system simulation and analysis
tools that incorporate both an accurate dynamic model of a
DFIG wind turbine and a realistic representation of a power
network [1]. This paper investigates the dynamic
performance of DFIG wind turbines in multiple machine
systems using three different network configurations: (i)
connection of the DFIG wind farm to an infinite bus through
a two-bus double circuit; (ii) connection of both DFIG wind
farm and local synchronous generation to the main grid
represented by an equivalent synchronous generator; and (iii)
connection of a large DFIG wind farm in a multi-machine
network. Results from computer simulations conducted in
IPSA are presented and commented. Data used for the
simulation models is provided in the Appendix.
