FORMATION OF BUS ADMITTANCE AND IMPEDANCE MATRICES AND SOLUTION OF NETWORKS

1. Using a text editor create an input file in the sequence given below for formation of    
Y and Z matrix for the 6-bus system. Check the results obtained using the available  Software. Run the program  and print the modified Y matrix for the 6 bus system for the removal
of the following components, one at-a-time:
  1. Line 4-6
  2.  Transformer 4-3
