Prior to 1950s the shunt capacitor banks (SCB) were placed nearer to the main substation for capacitive reactive power compensation, it helps in improving the power factor, reduces I 2 R power losses and improving the voltage profile. SCB changes the power losses up to the point of coupling, however to get the maximum benefit it must be placed as nearer to the

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.
The directions of the above two components oppose each other. Whenever an inductive load is connected to the transmission line, power-factor lags because of lagging load current. To compensate, a shunt capacitor is connected which draws current leading the source voltage. The net result is improvement in power factor.
Also, a series capacitor produces more net voltage rise than a shunt capacitor at lower power factors, which creates more voltage drop. However, a series capacitor betters the system power factor much less than a shunt capacitor and has little effect on the source current.

The shunt capacitor diagram is shown below: The capacitor bank’s rating can be known by implementing the below-stated formula which is Q = P (tanϴ – tanϴ’) Here, ‘Q’ corresponds to the amount of necessary KVAR ‘P’ corresponds to active power measured in kilowatts ‘cosϴ’ corresponds power factor before the compensation
The capacitive reactance (X_c) of a capacitor is defined as: Xc=12πfC Xc =2 πfC 1 Where: As the frequency of the alternating current (AC) increases, the capacitive reactance decreases. This relationship allows shunt capacitors to effectively counteract the inductive reactance generated by loads such as motors and transformers.
