Bouhadouza Boubekeur et al.: Application of STATCOM to increase transient stability of wind farm

According to the simulation results, the curves presented
above shows the importance of the compensation when the
wind farm recovers its operation after the fault and takes its
stability with some oscillation by the intervention of
STATCOM at bus bar 6.

4.2. With STATACOM
According to the previous simulation results, we added
the STATCOM at bus 6 for view the STATCOM effects.
Fig 12 and 13 shows the active and reactive power at the
load bus, we can note that in the both curves the two powers also stabilized faster with less oscillation compared with
the preceding case in the transient state and even after the
fault, however fig 14 and 15 shows the active and reactive
power for each wind turbine.
