This project presents comprehensive power system studies of a 13.8 kV substation network to improve power quality and operational reliability. Load flow analysis is carried out to evaluate voltage profiles, power losses and reactive power flow while maintaining a minimum lagging power factor of 0.95 at the Point of Common Coupling. Short circuit analysis is performed to determine fault current levels and verify equipment and protection adequacy. Motor acceleration studies assess starting currents, voltage dips and dynamic performance of large motors. Power factor improvement is achieved through optimal selection and placement of capacitor banks. The impact of capacitor switching, including transients and self excitation effects is evaluated. Harmonic analysis is conducted to ensure acceptable distortion levels. Transient stability of the system during disturbances is analyzed using ETAP. The study demonstrates improved voltage stability, reduced losses and enhanced system reliability.
