a Q3 The degree of series compensation for a series capacitor is 0.3 , transmission angle is 7 degree, the sending and the receiving end voltage are 1.0 pu, line reactance= 0.8 pu. Find the series compensating voltage of the SSSC such that transmitted power using both the series compensated methods is the same. Q4 The UPFC voltage source model has the following voltages and impedances : V=1+j0.15; V= 1+j0.05; Vpq=0.2+j0.15; V=0.7+j0.6; Zio=0.3+j0.4; Z;=0.1 +0.14. Calculate a) Active Power injection b) Reactive Power injection at both the buses. Derive the formulae used. Q5 The load angle increases from di to d2 and ds1 to 0,2 for an uncompensated and a series compensated system respectively when the fault occurs. The maximum angular swings are 83 and 8s3 for these systems. Calculate the margin of stability for these systems with the help of P- diagram. The degree of series compensation 0.3333, Mechanical power input =0.5 p.u., Maximul power for the uncompensated system occurs at 1/2 radians.
