A 3-bus power system is shown below. The three busses are connected through three 340 kVtransmission lines of 200km, 150 km, and 150 km long. These transmission lines have the seriesresistance of 0.05 Q/km and series reactance of 0.30/km. (a) Find the value of the transmission lines series impedances. (b) Find the bus admittance matrix (Y-bus) of this power system.
