| Abstract: Assessment and mitigation of the environmental impact of EHV power lines is a subject of current research due to the possible associated health hazards. The electric field beneath the line and the field on the conductor surface are known to be main sources of concern from an environmental standpoint. The present approach serves as means of reducing the electric field under EHVAC lines using ground shield wires. The aim is to determine the optimal ground shield wire heights and clearances to satisfy a set of field limitations on the conductors as well as on the ground. Genetic Algorithms, GAs, are employed to arrive at the required optimal clearances through an appropriate fitness function. The merits of the proposed approach are demonstrated for 3-phase horizontally-arranged 500 kV single circuit transmission line. Results show the effectiveness and accuracy of the proposed approach. | ||
