Abstract
As wind power plays a prominent role in reducing environmental pollution,
adjusting energy structure and easing Energy crisis, it has e a more and more
important part of renewable energy. With the rapid development of wind power in
China, variable-speed constant-frequency doubly-fed induction generator (DFIG) has
e the mainstream models in large-scale wind farm with its outstanding
advantages. It is meaningful to study modeling method of wind farm which is
composed of DFIGs and power control Strategy of wind farms, with its significant
help in reducing wind power impact on power grid and wind power scheduling.
According to State Grid Corporation's "wind power running control technology
requirements", this paper studied on wind posed of DFIGs, did the research
on the modeling of the wind farm and its power regulate and control methods. and
used PSCAD/EMTDC ic transient simulation platform as a tool for
simulation, analysis and verification.
This paper studies modeling and control theory technology of DFIG firstly. Then
the field oriented control technology is appl
