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.
Installing capacitors will decrease the magnitude of reactive power supplied to the inductive loads by the utility distribution system thereby improving the power factor of the electrical system. Capacitors are rated in “VARs”, which indicates how much reactive power is supplied by the capacitor.
In the method, the high-potential buses are identified using the sequential power loss index, and the PSO algorithm is used to find the optimal size and location of capacitors, and the authors in have developed enhanced particle swarm optimization (EPSO) for the optimal placement of capacitors to reduce loss in the distribution system.
From this, they developed the 2/3 rule for selecting capacitor size and placement to optimally reduce losses. For a uniformly distributed load, the bank Kaur size should be two-thirds of the KVAR as measured at the substation, and the bank should be located two-thirds the length of the feeder from the substation.
The results show that the approach works better in minimizing the operating costs and enhancing the voltage profile by lowering the power loss. Hybrid optimization of particle swarm (PSO) and sequential power loss index (SPLI) has been used to optimal capacitor allocation in radial distribution networks for annual cost reduction .
