Electrical energy demand is increasing exponentially due to the industrial and economic growth. Electricity has a fundamental role in the economic growth of any society as all the residential, commercial and industrial sectors are dependent on it. Pakistan is currently facing an energy crisis due to low power generation, high line losses and growing energy demand. An efficient electric power system, from generation to utilization, is needed to overcome such problems. Hence, the power system should be stable and fault tolerant. In this paper, static var compensators (SVCs) are used to improve undervoltage and low power factor problems in power system. A 132/11.5kV substation is used to analyze the improvements in these factors, which affects the power system performance. The substation is simulated on Electrical Transient Analyzer Program (ETAP) software to analyze the real time scenario of the power system with the complete load flow analysis. All the values and data are collected from the 132/11.5kV substation for the analysis and simulation for real time. The results clearly demonstrate the effectiveness of using SVCs in improving undervoltage and low power factor problems in power system.
