This may include improved voltage profiles, improved power factor, enhanced stability performance, and improved transmission capacity. The reactive devices are connected either in series or in parallel (shunt). Series capacitors are utilized to neutralize part of the inductive reactance of a power network.
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.
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.
Series capacitor compensation is an economic way of increasing the power transfer capacity of a line, but some of the potential gain in additional capacity may be lost when linear shunt reactors are permanently connected. Subsynchronous resonance conditions must be evaluated at the design stage, but techniques are now available for damping out SSR.
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.
Series capacitors also improve the power transfer ability. The power transferred with series Compensation as where, is the phase angle between V S and V R; Hence capacitors in series are used for long EHV transmission system to improve power transfer ability (stability limit).
