The single line diagram of a small power system isshown in Fig. 1. The corresponding reactancediagram, with reactances in per unit, is shown inFig. 2. A generator with emf equal to 1.25∠0° perunit is connected through a transformer to highvoltage node 3, while a motor with internalvoltage equal to 0.85∠ − 45° per unit is similarlyconnected to node 4. Develop the nodaladmittance matrix for each of the networkbranches and then write the nodal admittanceequations of the system.

Question 2. A 3.5 kW motor with 0.94 lagging power factor is supplied by a single phase power system. This power system is simply represented by a generator in series with a transmission line with an impedance 1+j3 2. If the voltage across the motor is to be kept at 220 V., Calculate the generator voltage, voltage regulation and losses on the transmission line when: (a) There is no capacitor in parallel with the load. (b) There is a capacitor so as to increase the overall power factor of the load to 0.98. (c) Calculate the connected capacitor value in farad or microfarad. (d) Calculate the difference in active, reactive and complex(VA) power losses.
