Abstract

Audible noise generated by the corona of HVDC transmission line has become one of the major considerations in the design of high voltage transmission lines. To research audible noise space propagation characteristics duo to HVDC transmission lines is very important for the analysis of the spatial frequency spectrum characteristics of the audible noise, and it can provide the basis for the transmission line audible noise environment. Absorption attenuation of expression, and expression as well as the atmosphere of the semi-free-space point source sound pressure wave superposition principle to calculate the space of a HVDC transmission line audible noise spectrum distribution. Then discuss the spatial propagation characteristics of high voltage direct current transmission line audible noise under different weather conditions. The analysis results show that: As the the atmospheric absorption attenuation, HVDC transmission line audible noise spectrum in the case of low-frequency, but a greater impact in the high-frequency case.And under different weather conditions, the high-frequency part of the spectrum changes Larger.
