Capacitor Bank Definition: A capacitor bank is a collection of multiple capacitors used to store electrical energy and enhance the functionality of electrical power systems. Power Factor Correction: Power factor correction involves adjusting the capacitor bank to optimize the use of electricity, thereby improving the efficiency and reducing costs.
For power factor correction, the capacitor bank is used to connect with the load. If the load is a three-phase load, the capacitor bank can be connected as a star and delta connection. The below circuit diagram shows delta connected capacitor bank with a three-phase load.
The consequential improvement in power quality is accompanied by a decrease in electricity costs, aligning with the broader goals of energy efficiency. Additionally, capacitor banks function as harmonic filters, addressing and minimizing harmonic distortions in the electrical system.
Capacitor banks play a pivotal role in substations, serving the dual purpose of enhancing the power factor of the system and mitigating harmonics, which ultimately yields a cascade of advantages. Primarily, by improving the power factor, capacitor banks contribute to a host of operational efficiencies.
The selective capacitor from the bank will be switched ON/OFF based on reactive power being compensated. This design shows the switching of the capacitor bank in five steps for improving the lagging PF (towards unity). This is implemented by switching three relays and two transistor outputs.
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.
