Causes of over voltage are usually switching, lightning and parallel resonance. The most dangerous of these reasons can be the parallel resonance. The parallel resonance occurs between system impedance and capacitors of reactive power compensation of electrical plant. Before an electrical plant (any factory) is connected to connection point of power line of electrical network, parallel resonance of connection point of power of power line must be determined previously to prevent parallel resonance. Otherwise, system impedance increases extremely during parallel resonance, and if current of system (50Hz) encounters high impedance during parallel resonance, high voltage occurs on electric network. So, total capacitor power should be less than the parallel resonance power. In this study, the application which related to determination of parallel resonance power was made by using PSO, and also effect of inertia weight on PSO was examined for this study. Thus parallel resonance power of low voltage electric network can be calculated and maximum capacitor of compensation system can be determined.eninfo:eu-repo/semantics/closedAccessInertia weightover-voltageparallel resonanceparallel resonance powerPSOConference ObjectN/AWOS:000343672500055N/A
