Load and distributed generation characteristics have both changed to require increased VAR support throughout the power system. Substation capacitor banks are the most economical form of adding VARs to the system, yet because of harmonics, grounding, and operational concerns, there are many different types of capacitor banks.
The application of capacitors on a substation bus causes severe capacitive current switching duty. Compare rated capacitive switching current for the existing breakers with the anticipated duty to determine the need for breaker mechanism modifications. Consult the breaker manufacturer to determine the need for such modifications.
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:
Figure 5: Capacitor Banks at a Substation However, the employment of capacitor banks at substations stands as their most important application. They are also used in various other applications, though their size might change according to the size of the system. Cars: These banks are used in electric or hybrid vehicles to store electricity.
So, a resistor is also used in series with a capacitor bank to control the flow of inrush current. These banks need some switching devices, such as transistors or relays, to regulate their connectivity with the electrical systems.
