Series-Compensated Transmission System
To increase the transmission capacity, each line is series compensated by capacitors representing 40% of the line reactance. Both lines are also shunt compensated by a 330 Mvar shunt reactance. The shunt and series compensation equipment is located at the B2 substation where a 300 MVA-735/230 kV transformer feeds a 230 kV-250 MW load.

Series and Shunt Compensation of Transmission Lines:
Here X C = capacitive reactance of the series capacitor bank per phase and X L is the total inductive reactance of the line/phase. In practice, X C may be so selected that the factor (X L — X C) sin Φ r becomes negative and equals (in magnitude) R cos Φ r so that ΔV becomes zero. The ratio X C /X L is called "compensation factor" and when expressed as a percentage is known
