Abstract: Series capacitive compensation method is very well known and it has been widely applied on transmission grids; the basic principle is capacitive compensation of portion of the inductive reactance of the electrical transmission, which will result in increased power transfer capability of the compensated transmissible line.
Definition: Series compensation is the method of improving the system voltage by connecting a capacitor in series with the transmission line. In other words, in series compensation, reactive power is inserted in series with the transmission line for improving the impedance of the system. It improves the power transfer capability of the line.
Load Division among Parallel Line – Series capacitors are used in transmission systems for improving the load division between parallel lines. When the new line with large power transfer capability is paralleled with an already existing line, then it is difficult to load the new line without overloading the old line.
The transmission line is split into two 300 km lines connected between buses B1, B2, and B3. Series and Shunt Compensated Transmission System To increase the transmission capacity, each line is series compensated by capacitors representing 40% of the line reactance.
Series capacitors also improve the power transfer ability. The power transferred with series Compensation as where, is the phase angle between V S and V R; Hence capacitors in series are used for long EHV transmission system to improve power transfer ability (stability limit).
Series capacitors also help in balancing the voltage drop of two parallel lines. When series compensation is used, there are chances of sustained overvoltage to the ground at the series capacitor terminals. This overvoltage can be the power limiting criterion at high degree of compensation.
