The electric energy loss in overhead ground wires of 110kV six-circuit transmission line on the same tower

摘要

In order to provide theoretical guidance for reducing the electric energy loss of 110kV six-circuit transmission line on the same tower, the factors affecting electric energy loss in overhead ground wires are deeply studied. Firstly, the model of 110kV six-circuit transmission line on the same tower is established in MATLAB. Secondly, the effect of phase sequence arrangements on electric energy loss is studied. Finally, the effects on electric energy loss of varying relative position between two overhead ground wires, horizontal distance and vertical distance among transmission lines are studied. The results show that phase sequence arrangements have a great influence on power loss in overhead ground wire. The inverse phase sequence arrangement is validated to be optimized layout. The electric energy loss is positively correlated with horizontal distance between two overhead ground wires and negatively correlated with vertical distance from overhead ground wires to the ground.
