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.
The reduction of the series inductance of the transmission line by the addition of the series capaci-tor provides for increased line loading levels as well as increased stability margins. This is apparent by reviewing the basic power transfer equation for the simplified system shown in Figure 2. The power transfer equation is:
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.
Advantages & Location of Series Capacitors - Circuit Globe 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.
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.
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.
