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.
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.
Thus with series capacitor in the circuit the voltage drop in the line is reduced and receiving end voltage on full load is improved. Series capacitors improve voltage profile. Figure 2 Phasor diagram of transmission line with series compensation. Series capacitors also improve the power transfer ability.
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.
Voltage drop in the line reduces (gets compensated) i.e. minimization of end-voltage variations. Prevents voltage collapse. Steady-state power transfer increases; it is inversely proportional to X′ l.. As a result of (2) transient stability limit increases. The benefits of the series capacitor compensator are associated with a problem.
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.
