The invention discloses a method for adjusting electric transmission line wire phase sequence arrangement according to current phase angles and amplitude values. The problem that the unbalance degree of three-phase currents of an existing electric transmission line is aggravated is solved. The method comprises the steps that according to the tower types adopted by a single transmission line and common-tower double transmission lines and the length of the actual lines, a calculation model is built through an electromagnetic transient calculation method, and simulation calculation is carried out. A complete-cycle Fourier data analysis program is compiled, Fourier complete-cycle filtering is carried out on current discrete data in the simulation calculation, fundamental current amplitude values and the phase angles of three phases A, B and C are filtered out, the current amplitude values and the phase angles of a fundamental positive sequence, a fundamental negative sequence and a fundamental zero sequence are respectively calculated, and the angel differences between the three phases A, B and C are calculated. The unbalance degree of current phase positions and the amplitude values is calculated through the amplitude value of the fundamental positive sequence and the angel differences between the three phases A, B and C. The calculated unbalance degree of the current phase positions and the amplitude values is controlled to be smaller than 5%. False operations of zero-sequence protection of buses and electric transmission lines of a transformer substation are avoided, and the safe operation of a power grid is guaranteed.
