1. The bus admittance matrix and the voltages for the following three bus power system are given in pu system. Perform a Newton-Raphson power flow analysis to calculate the bus voltages at the end of second iteration. Consider that the flow equations are decoupled as given by the relationship, AP 0 48 -j20 j10 jlo j10 j10 j10 - 120 Yus J10-j20 The base MVA is 150. Bus 1 2 3 Type Slack PV PQ P.
