Abstract
This paper presents for modeling of the 500 kV EHV parallel transmission lines of multi circuit for the effect of induced voltages in transient stability due to a direct strokes using a modified genetic algorithm. The study of induction from the energized line with higher voltage(HV)level is more than the induction from the energized line with lower voltage level. Phase sequencing and transposition of lines, which changes the distance between the energized, effects the induced voltage in each section along the lines. The grounding of sending and receiving ends of energized lines causes high induced current in the circuit. The ground switch is connected to ground for off-service long transmission line to discharge to because the voltage in hotline circuit can induce to open line using a modified genetic algorithm. The voltage must be calculated along the distance of transmission line to fix the ground point connected by for safety of operator.
