Reducing the inductive reactance can be done by either installing bundled conductors (25-30% reduction) or by series compensation. Series compensation is a wonderful electrical "trick". How it''s done. Series compensation involves inserting a capacitor bank in series with each of the three phases of the transmission line.
Thus, by compensating the series reactance to a certain degree, using a series capacitor, an electrically shorter line is realized and higher active power transfer is achieved. Installing a capacitive reactance in series in a long (typically more than 200 km) transmission line reduces both the angular deviation and the voltage drop, which increases the loadability …
