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.
