BUS ADMITTANCE MATRIX - PART – 07 – FORMATION OF Y-BUS - ONE PROBLEM

PROBLEM

(a) A 3-phase transmission line bus 230 kV, 250 MVA, 400 km line of a symmetrical type. Find the bus admittance matrix for the two bus system. Assume R = 0.075 ohms, L = 1.5 mH, C = 12 nf.

(b) A shunt capacitance of 1.5 mf is connected to bus 1 and 2 mf is connected to bus 2. form the new Y-bus matrix.
