Abstract

The invention provides a method for changing a power network parameter. According to the technical scheme, the reactance in a circuit is reduced, the circuit reactance of a split lead adopted for ultrahigh voltage can be obviously reduced, a 220KV circuit adopts two split leads, and a 500KV circuit adopts four split leads. The method has the advantages that the reactance in the circuit is reduced, the electric filed intensity around the leads also can be reduced, the corona discharging is reduced, and energy sources are saved.

Description

Technical field [0001] The invention relates to the field of power supply technology, in particular to a method for changing power grid parameters. Background technique [0002] At present, the power supply grid adopts a unified operation mode, ignoring the problems of power supply quality and energy saving, which seriously affects the power supply quality of the line, causes losses to production and life, and wastes national property. Summary of the invention [0003] The invention provides a method for changing power grid parameters. The technical solution is to reduce the reactance in the line. The split conductor used in the ultra-high voltage can significantly reduce the reactance of the line. The 220KV line uses two splits and the 500KV line uses four splits. [0004] The present invention has the beneficial effects of reducing the reactance in the line, reducing the electric field intensity around the wire, reducing corona discharge and saving energy. detailed description ...
