Method for inhibiting induction voltage and current of 750kV parallel single-line construction line

The invention relates to a method for inhibiting an induction voltage and an induction current of a 750kV parallel single-line construction line. Two large-distance parallel and single-line construction 750kV alternating current transmission lines are coupled on an off-the-line line to generate a higher induction voltage and a higher induction current to ensure that the problem of difficult equipment selection caused by exceeding the turning on or off capacity of the existing 750kV earthing switch is solved. The invention provides a transposition and phase sequence arrangement mode to ensure that levels of the induction voltage and the induction current applying the measure are remarkably reduced and are lower than the requirement on technical parameters of the existing equipment, and thus the equipment selection problem is solved.
