Hello Mr. Zeya,
Its not very clear that what exact formula are you using for calculating
the susceptance. However following is the way to calculate B in p.u.
For the first row in your data:
Total capacitance = C = 1.046429 \micro F
Total charging capacitive reactance = X_c = 1/{2*pi*50*C} = 3041.86 \Ohms
Total charging capacitive susceptance = B_c = 1/3041.86 = 3.2875 * exp^{-4}
Total charging capacitive susceptance per unit = B_{c,p.u.} = B_c / Y_b
Y_b = 1/Z_b = 1/529
Total charging capacitive susceptance per unit = B_{c,p.u.} = 3.2875 *
exp^{-4} * 529 = 0.1739 p.u.
Sohail.
