Figure 24 . Response on Overhead Line energization for a DFIG based hybrid system.
From above, it was possible to energize at least 50km of overhead line without any form of compensation. Some form of compensation was required for lines above this and this is seen in the energization of the 100km and 200km lines. Since the lines were being energized at 0.9pu, the rise in voltage was not significant as compared to cable energization earlier mentioned. On investigating the missing zero phenomenon on the SC stator current, Fig. 25 shows the results obtained.
