A simple power transmission system shown in Figure Q2 has two transmission lines. It is assumed that Vs = VR = 132 kV, f = 50Hz, phase shift 8 = 25°, X = 50 % on a 132 kV/100 MVA base. 2.1 Calculate the active and reactive power flows for both ends and the reactive power absorption by the transmission lines. 2.2 If the total transmitted active power between the two ends is to be increased by 40% using series compensation on one of the transmission lines, illustrate two possible techniques that can be used, giving the ratings of the respective series compensators. 2.3 If the resistances of the transmission lines are considered, comment on how this would affect power transmission and series compensation, illustrating your answer by referring to an example of the P- & characteristic.
