Abstract
The rotor structure varies with different types of wind
power induction generator (WPIG), which leads to their different
dynamic behaviors during power system disturbances. This paper
proposes a generic implementation framework of explicit damping
torque analysis to investigate the damping mechanisms of power
system integrated with induction generator based wind power
generation, so that the essential difference and inner connection
between two main types of WPIG (i.e., DFIG and FSIG) in
damping power system oscillation can be revealed. The linearized
models which can represent DFIG and FSIG as well as three
transitional wound rotor generators are established to facilitate
the analytical comparison analysis. Phillips-Heffron system
linearized model is employed to derive an explicit expression of
damping torque contribution from main dynamic components of
WPIGs. In the paper, 16-machine 5-area NYPS-NETS example
system is used for the demonstration of proposed framework and
comparison analysis. Both damping effectiveness and robustness
of different WPIGs are extensively examined under multiple
operating status, in order to provide useful guidance to system
planner for the real-time operation of induction generator based
wind generation.
