Assume we have an N-bus power system and we know the N x N zero-sequence, positive-sequence, and negative sequence matrices for the system. Write a MATLAB program to find the system bus voltages during a:
(a) 3-phase balanced short circuit fault at an arbitrary bus ?
(b) One-line-to-ground short circuit fault at an arbitrary bus ?
(c) Line-to-line short circuit faults at an arbitrary bus ? and
(d) Line-to-line-to-ground short circuit faults at an arbitrary bus ?
