In general, the line ratings RATE_A, etc, would also equal the sum of the
individual line ratings, but in this case the capacity limit is not given
(interpreted as unlimited) so no change.
However, a quick correction … while the total impedance (r and x) are halved,
the total line charging (b) is doubled.

Hello Matpower users,
I want to remove duplicate branches in IEEE 118 bus system and put an
equivalent one. For example:
fbus tbus r x b rateA rateB rateC ratio angle status angmin angmax
duplicate branches:
42 49 0.0715 0.323 0.086 0 0 0 0 0 1 -360 360;
42 49 0.0715 0.323 0.086 0 0 0 0 0 1 -360 360;
equivalent branch:
42 49 0.0357 0.1615 0.0430 0 0 0 0 0 1 -360 360;
Is it sufficient to only change r, x and b to equivalent one or do I need to
have more changes?
Thanks,
Naime
