How does a shunt capacitor work?

Shunt capacitors reduce the induced current in the electrical circuit. Reducing the line current reduces the IR and IX voltage drops and improves the system voltage level from the capacitor to the source. In both distribution and transmission systems, it is necessary to maintain the voltage between 0.95-1.05 units.

Why does a shunt capacitor cause a voltage rise?

Every transformer on the power system from the location of the capacitor bank to the generator will experience a voltage rise. This is an important component of the voltage rise due to the shunt capacitor.

How does a shunt capacitor bank increase voltage?

The addition of a shunt capacitor bank raises the voltage at the point of installation. The voltage drop equations without shunt capacitors (VD1) and with shunt capacitors (VD2) are (Natarajan, 2005): Where ( KVA 1 cos KVA 2 cos 2 ) is the change in the real power, which is equal to zero.

What are the benefits of using a shunt capacitor?

The benefits of the system due to the use of shunt capacitors include power factor correction, reactive power support, line and transformer loss reduction, power system capacity release, energy savings due to increased energy loss, voltage profile improvement, and active power transmission capacity increase.

Why do generators use shunt capacitors?

The use of shunt capacitors to supply the forward currents required by the load relieves the generator from supplying that part of the induced current and also achieves the desired KVAR capacity (Gönen, 2014). 2.1. Voltage Profile Improvements Shunt capacitors reduce the induced current in the electrical circuit.

Why are shunt capacitors used in EHV substations?

Usually extra-high voltage (EHV) lines are used to transmit bulk power from remote generations to load centers. These long lines tend to produce significant voltage drops during peak loads. Therefore, shunt capacitors are used at the EHV substationsto provide reactive power. Sometimes these capacitor banks are switched as and when required.
