Reactive Power Compenstation in Distribu

This article provides comprehensive information about reactive power compensation implemented in distribution systems to reduce power losses. A case study focusing on the MPPKVVCL substation in Jabalpur, India, featuring an 8MVA capacity at 33/.4 kV, was conducted to analyze the effectiveness of shunt capacitor banks in comparison to scenarios without these banks during peak usage hours. Data from the load curve indicated that the activation of the shunt capacitor bank resulted in a current drop of approximately 10-12 Amperes in the 11 kV line, thereby alleviating the strain on devices connected to the 11 kV feeder. The preserved current was redirected to other customers, enhancing power accessibility. Moreover, MATLAB simulations demonstrated the current reduction in the 11 kV feeder upon the inclusion of the shunt capacitor bank. Economic analysis utilizing annuity concepts was also performed to quantify lifecycle cost savings associated with the implementation of shunt capacitors. This methodology is broadly applicable for assessing actual savings in any distribution system where shunt capacitors are leveraged.
