Please do the hand calculation as well together with the formula and working. As the question mentioned, matlab code as well please.

Write a Matlab program to verify the manual calculation results for the given problem. Problem: Consider a system which consists of generator having a rating of 50 MVA & H=2.7 MJ/MVA at rated speed. E=1.05, V=1, Xd; =0.2, X2=X2=0.4 p.u. The generator supplies 50 MW to the infinite bus when a 3phase fault occurs at middle of line 2. i) Plot the swing curve for a sustained fault up to 0.5 sec. ii) Plot the swing curve if the fault is cleared in 0.1 sec by simultaneous opening of breakers at both ends of line 2. iii) Find the critical clearing angle & clearing time.
