Abstract: |
The doubly fed induction generator (DFIG) is
major type of wind turbine generator used in grid-connected
wind farms. Practical models of DFIG have been
built to study the influence of wind power generation on
power system dynamics. However, most existing practical
models of the DFIG are based on rectangular coordinates,
in which frequency variation is neglected. In this paper, a
phase–amplitude (P–A) model is proposed for a DFIG
based on phase and amplitude of the internal voltage. The
model structure is much like that of the synchronous generator,
and the rotor voltage can manipulate both the
amplitude and the phase of the internal voltage.
Comparisons have been made between the new P–A model
of the DFIG and the synchronous generator model, as well
as the asynchronous motor model. The contributions of the
new P–A model of the DFIG are discussed and it is
demonstrated that the proposed model has better ability in
describing power system dynamic phenomena such as
voltage dynamics and structural dynamics in general.
Simulation results and a field test validate these
contributions. |
