For the system attached, we want to increase the power transfer from Bus 1 to Bus 2 by adding a SVC at the midpoint. (a) Calculate the power transformer from Bus 1 to Bus 2 if the SVC is disconnected. (B) suppose the SVC is connected through a 18:1 transformer with a leakage reactance of 0.005ohm on low voltage side, determine the MVAR requirements for the SVC to do the following: (i)Increase P12= 650MW with the TCR is not gated. (ii) How much capacitance and inductance is needed to increase P12 to 633MW with the TCR operating with ? = 75 deg. Assume Delta connection of the TCR and Capacitors (iii) Modify your solution for a 12 pulse SVC (one TCR in Delta and the other in delta)
