Power Factor Improvement by Shunt Capacitor Bank at 33 Kv Busbar in a Distribution Substation

Power factor (PF) is one of the important aspects affecting the performance of the electrical network. This phenomenon results from an increase in inductive loads, which leads to lower voltage, increase losses, and lower efficiency in the electrical network. Different types of shunt capacitor bank (SCB) configurations are installed in the distribution substation (DS), which can be grounded or ungrounded, fused or without fuses. These SCBs provide voltage support, power factor correction, power transport increment, loss reduction, and enhancement of system quality. This paper presents the evaluation of two fixed SCBs isolated by isolator at 33 Kv busbar in DS for PFC. The work is simulated and analyzed using MATLAB.
