Control of Voltage – In series capacitor, there is an automatic change in Var (reactive power) with the change in load current. Thus the drops in voltage levels due to sudden load variations are corrected instantly. The location of the series capacitor depends on the economic and technical consideration of the 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.
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.
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.
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).
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.
