Abstract

The invention provides a voltage level identification system and method for a high voltage AC / DC power line. The method is characterized in that a drone is equipped with multiple sets of electric field sensors, an electric field intensity coefficient is calculated according to electric field intensity values collected by the electric field sensors, the calculated electric field intensity coefficient is matched with an electric field intensity coefficient of the high voltage AC / DC transmission line under different voltage levels at the preset vertical distance d, and a voltage level corresponding to the electric field intensity coefficient of the high-voltage AC / DC transmission line under the preset vertical distance d closest to the calculated electric field intensity coefficient is determined as a voltage level of the high-voltage AC / DC line. The method is advantaged in that different voltage levels of the high-voltage AC / DC transmission line can be accurately and automatically identified, working efficiency of operators is improved, and safety of power field operation is enhanced.

Description

technical field [0001] The present application relates to the technical field of power measurement, and in particular to a voltage level identification system and method for high-voltage AC-DC transmission lines. Background technique [0002] With the increasing application of power transmission in the power industry, the proportion of electric energy it transmits in the power grid is increasing, and the problems of protection, monitoring and detection of DC transmission are also highlighted. High-voltage direct current transmission projects have two basic characteristics: high equipment structure parameters and high operating parameters. At the same time, EHV / UHV AC / DC transmission lines also have the characteristics of tall towers, large tower heads, and long insulator strings. In addition to factors such as high-altitude operations, the space around the equipment has higher field strength, and the determination of the high-voltage level is correspondingly There are highe...
