Use of capacitive (shunt compensation) on various part of the power system improves power factor, Reduce power losses, improves voltage regulation and increased utilization of equipment. Reference: Electric power generation, Transmission and distribution by Leonard L.Grigsby. Power system supply or consumes both active and reactive power.
Series capacitors are very effective when the total line reactance is high. Series capacitors are effective to compensate for voltage drop and voltage fluctuations. Series capacitors are of little value when the reactive power requirements of the load are small.
The inductive and capacitive reactances are frequency dependent (hence are only present in AC systems), oppose each other and are at right angles to the pure (DC) resistance. The net reactance, which is usually inductive, opposes the flow of current, and the power required to overcome this reactance is called reactive power (Q).
Having said the types of compensation, in this article we are going to discuss mainly about Shunt compensation using Capacitor bank. Since most loads are inductive in nature they consume lagging reactive power, so the compensation required is usually shunt capacitor bank. Shunt capacitors are employed at substation level for the following reasons:
This aids in maintaining the voltage level in the system. The high inductive component of the starting current is reduced by the addition of capacitance during the starting period only. In this, it differs from applying capacitors for power factor correction.
