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.
This research paper has explored the principles of reactive power compensation and the protection methodology of shunt capacitor banks. A discussion on the application of shunt capacitor banks and their location showed that an installed mix of supply side and load side is preferred.
Since the detuning factor for the project was given as p=7%, one knows that the capacitor bank needs to be equipped with reactors. For this reason, some calculations have to be performed, in order to fit the power of the capacitors and its rated voltage taking into account reactive power of a detuning reactors.
Due to reduced active power losses inside the capacitors, today it is possible to assemble compensation banks up to 400 kvar or more within one cubicle of dimensions (B × H × W) = 600 mm × 2000 mm × 400 mm (without reactors). 1. Installation requirements
Having said the types of compensation, in this article we are going to discuss mainly about Shunt compensation using Capacitor bank. Since most loads are inductive in nature they consume lagging reactive power, so the compensation required is usually shunt capacitor bank. Shunt capacitors are employed at substation level for the following reasons:
In determining the power cables to the compensation bank, their cross-section must not depend on the nominal current but on a higher value. According to the European standards EN 60831-1 for LV capacitors and EN 60871-1 for MV capacitors, they must be constructed to lead the nominal current steadily by 1.3 times.
