ABSTRACT: Nowadays with the improvement in the degree of emphasis
on new energy, the wind power system has developed more and more rapidly over
the world. Usually the wind plants are located in the remote areas which are
far from the load centers. Generally series compensated AC transmission and
high voltage DC transmission are made use of to improve the transmission
capacity as two main effective ways which can solve the problem of large scale
wind power transmission. The paper describes the three kinds of impact varieties and
impact mechanisms in the sub-synchronous oscillation phenomena of wind power system
based on doubly fed induction generator (DFIG) wind generators. At last, we
point out the important problem that should be stressed in the wind power
system.
