Shunt Capacitor Definition: A shunt capacitor is defined as a device used to improve power factor by providing capacitive reactance to counteract inductive reactance in electrical power systems. Power Factor Compensation: Shunt capacitors help improve the power factor, which reduces line losses and improves voltage regulation in power systems.
Compensation capacitors are divided into two type families (A and B) in accordance with IEC 61048 A2. • Type A capacitors are defined as: "Self-healing parallel capacitors; without an (overpressure) break-action mechanism in the event of failure". They are referred to as unsecured capacitors.
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.
Load division increases the power transfer capability of the system and reduced losses. 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.
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.
