This study proposes a new method for measuring the unbalance of the multiple-circuit transmission lines (MCTLs) on the same tower, which can characterise the physical natures of the line unbalance. First, the impedance and the sequence current of the MCTLs on the same tower are calculated under the consideration of the impact of ground wires. Then, the unbalance suppression methods of the optimal...
In order to provide guidance for construction and operation of 110kV six-circuit transmission line on the same tower, the electromagnetic environment of transmission line is researched intensively. Firstly, the model of 110kV six-circuit transmission line on the same tower is established in MATLAB. Secondly, the power frequency electric field intensity, the power frequency magnetic field density and...
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...
