Using Matlab SMath Studio or other CAD software package veri

Using Matlab, SMath Studio, or other CAD software package, verify that you can reproduce the ZBUS result from the YBUS matrix listed below: Y_BUS = -j [14.5 -8 -4 -2.5 - 8 17 - 4 - 5 - 4 - 4 11.3333 0 -2.5 - 5 0 10.8333] Z_BUS = 1/Y_BUS = [0.2436 middot i 0.1938 middot i 0.1544 middot i 0.1456 middot i 0.1938 middot i 0.2295 middot i 0.1494 middot i 0.1506 middot i 0.1544 middot i 0.1494 middot i 0.1954 middot i 0.1046 middot i 0.1456 middot i 0.1506 middot i 0.1046 middot i 0.1954 middot i]

Solution

>> y=-i*[14.5 -8 -4 -2.5; -8 17 -4 -5;-4 -4 11.3333 0; -2.5 -5 0 10.8333]

y =

0 -14.5000i 0 + 8.0000i 0 + 4.0000i 0 + 2.5000i
0 + 8.0000i 0 -17.0000i 0 + 4.0000i 0 + 5.0000i
0 + 4.0000i 0 + 4.0000i 0 -11.3333i 0
0 + 2.5000i 0 + 5.0000i 0 0 -10.8333i

>> z=inv(y)

z =

0 + 0.2436i 0 + 0.1938i 0 + 0.1544i 0 + 0.1456i
0 + 0.1938i 0 + 0.2295i 0 + 0.1494i 0 + 0.1506i
0 + 0.1544i 0 + 0.1494i 0 + 0.1954i 0 + 0.1046i
0 + 0.1456i 0 + 0.1506i 0 + 0.1046i 0 + 0.1954i

Thus it has done.
