Abstract:
 Abstract:Considering the shaft torsional vibration risk of the turbogenerator caused by the integration of
large capacity wind farms in wind&thermal power transmission system,the impact of doubly fed induc-
tion generator(DFIG)-based wind farms interconnected to power grid on subsynchronous oscillation of
turbogenerator was investigated. Firstly,the detailed mathematical models for the small signal stability a-
nalysis with DFIG-based wind farms were established. By utilizing modal analysis method,the changes of
the system subsynchronous oscillation modes with and without DFIG-based wind farms were investigated,
respectively,and the presented models and modal analysis were demonstrated by comparison with the
time-domain simulation results. Then,based on the concept of parameter sensitivity,the analytical sensi-
tivity expression of subsynchronous oscillation damping ratio on wind farm parameters was deduced. Fi-
nally,Regarding for the different conditions of wind speed and reactive power of the wind farms,the vari-
anon of subsynchronous oscillation mode was discussed. The results show that the connected DFIG-based
wind farm could reduce the subsynchronous oscillation damping in keeping the external condition. Fur-
thermore,the parameters of active power and reactive power of the wind farms have an obvious effect on
the system subsynchronous oscillation damping.
