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 capacitor compensation reduces a line''s total impedance. It improves voltage regulation, increases the voltage-collapse limit of the line, improves the first swing stability limit of the system, improves reactive power balance, reduces transmission losses, and allows the line to be operated closer to its thermal limit [3], [4], [5] .
