Description

A kind of HVDC transmission line audible noise computing method
Technical field
The invention belongs to the acquisition methods of audible noise in the power domain, be specifically related to a kind of HVDC transmission line audible noise computing method of 4-8 split conductor.

The electromagnetic environment problem of extra high voltage direct current transmission line is extra high voltage direct current transmission line design, construction and the key technical problem that must consider in service.China takes the lead in studying and successfully having built ± 800kV extra-high voltage direct-current transmission engineering in south in the world, and with further research and development ± 1100kV extra-high voltage direct-current transmission engineering.Along with the raising of DC transmission engineering electric pressure, the control of the noise of transmission line of electricity seems particularly important, and it has become one of the conditionality factor in decision line construction and corridor.
A kind of people's ear that audible noise produces when being guide line surrounding air ionic discharge can direct audible noise.This noise may make near the high-tension line the resident or the staff has the fidgets and uneasy; Audible noise is the same with radio interference; Increase along with the increase of conductive line surfaces electric field intensity, but audible noise is slower than the horizontal decay in radio interference road along the line.External research shows that for 750kV and above circuit, audible noise will become distinct issues.
