In this paper, dynamics of a high-penetration, no-storage wind-diesel (HPNSWD) system subjected to line faults are studied. It is found that the effect of induction generator electrical parameters on generator electromagnetic torque, system frequency and generator terminal voltage is significant, especially for the rotor resistance, which is able to significantly affect all the three target performances. Therefore, it will be the most effective way to improve the system dynamics by controlling the rotor resistance. It is also found that the system dynamics would be significantly improved by disposing a distribution transformer. However, the effectiveness depends on the installation position. A distribution transformer installed at the generator side will just reduce the generator terminal voltage and electromagnetic torque disturbance. If it is installed at the load side, all of the three system performances can be significantly improved.
