Control of voltage. Series capacitors are used in transmission systems to modify the load division between parallel lines. If a new transmission line with large power transfer capacity is to be connected in parallel with an already existing line, it may be difficult to load the new line without overloading the old line.
The benefits of applying series capacitors on a transmission line include improved stability margins, better load division on parallel paths, ability to adjust line load levels, reduced transmission losses, and reduced voltage drop on the system during severe disturbances.
A discussion of their effect on the overall protection used on series compensated lines. First, however, a brief review will be presented on the application and protection of series capacitors. Series capacitors are applied to negate a percentage of and hence reduce the overall inductive reac-tance of a transmission line.
In a transmission system, the maximum active power transferable over a certain power line is inversely proportional to the series reactance of the 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.
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.
Because series capacitors are installed in series on a transmission line, the equipment must be elevated on a platform at system voltage, fully insulated from ground . The capacitor bank together with the overvoltage protection circuits are located on this steel platform.
