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.
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.
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.
Some of the more common compensation schemes are as under. Capacitor and/or reactor series compensator act to modify line impedance. An alternative approach is to introduce a controllable voltage source in series with the line. This scheme is known as static synchronous series compensator (SSSC).
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.
