| Abstract | The induced voltage generated in the transmission lines has been a significant factor for the power system because it can impact the stability and cause the work hazard to the system. This paper purposes the investigation of induced voltage occurring in 115 kV parallel transmission lines caused by electric filed induction. The dependence of induced voltage on the distance between the parallel transmission lines and conductor diameter are examined. This study performs the alternative transient program - electromagnetic transient program (ATP-EMTP) modeling to analyze the induced voltage. It was found that the induced voltage is decreased when the distance between the transmission lines are increased. For the impact of conductor diameter on the induced voltage, it was seen that the induced voltage can be reduced by decreasing the conductor diameter. Hence, the induced voltage generated in the transmission line and conductor diameter becomes the important factors, which is needed to be optimized in order to achieve the high stability power system. |
