A shunt capacitor bank is used in a substation to improve the power factor, reduce reactive power, and stabilize voltage. It helps the system use energy more efficiently by balancing the power supply and demand. Where should a capacitor bank be installed?
In this section, we delve into a practical case study involving the selection and calculation of a capacitor bank situated within a 132 by 11 KV substation. The primary objective of this capacitor bank is to enhance the power factor of a factory.
Therefore, to improve system efficiency and power factor, capacitor banks are used, which lessen the system's inductive effect by reducing lag in current. This, ultimately, raises the power factor. So, we can say that capacitor banks reduce power losses by improving or correcting the power factor. They are commonly used for these three reasons:
This lagging reactive power is supplied to the electrical load whose power factor is to be improved. Therefore, a capacitor bank if connected in an electrical system, it compensates the requirement of lagging reactive power and hence improves the power factor of the system.
