a) Describe the parallel and series forms of Flexible A.C. Transmission Systems (FACTS) that exist to improve the transmission of electricity. (10 Marks) b) Identical shunt reactors are connected from each phase conductor to neutral at both ends of a 300 km line during light load conditions, providing 50% compensation. The reactors are removed during heavy load conditions. Full load is 1 kA at unity power factor and at 400 kV. The A and B parameters for the line are A = 0.94 20.21° and B = 97.2 2880 and the admittance of the equivalent a circuit is = 3.75 x 10-7 + j7.1 x 10-45 Assuming that the sending-end voltage is constant, determine the following: (i) Percentage voltage regulation of the uncompensated line. (4 Marks) (ii) The equivalent shunt admittance and series impedance of the compensated line. (6 Marks) (iii) Percentage voltage regulation of the compensated line. (5 Marks)
