AI Customer ServiceWe have seen that a capacitor bank is used for the improvement of power factor and reactive power compensation in a substation. As the role of this bank is very important, it becomes critical to see that the bank is maintained well. Also, it has to be seen which parameters of this bank should be specified for installing it into the substation.
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.
The uniqueness of this scenario lies in the decision to install the capacitor bank at the 11 KV voltage level, even though the factory receives power from the grid at a higher voltage level of 132kV, with an approved connection capacity of 12 megawatts.
Moreover, the protection settings for the capacitor bank unfold systematically, elucidating the process of selecting the current transformer ratio, calculating rated and maximum overload currents, and determining the percentage impedance for fault MVA calculations.
The primary objective of this capacitor bank is to enhance the power factor of a factory. Local regulatory standards dictate that the power factor for bulk supply connections must be maintained at 0.9 or higher.
Moreover, surge arrestor protection is implemented for the capacitors, as illustrated in Figure 3, which depicts the single-line diagram of the capacitor bank. Three surge arrestors are installed, with one safeguarding each phase. Figure 2 – Double Star Connection: Illustration of Capacitor Bank Configuration
