摘要：
In order to study the characteristics of corona- generated audible noise (AN) from HVDC lines at high altitude area, based on the three DC reduced-scale test lines at 1700m, 3400m and 4300m elevation, the AN test of bipolar HVDC lines with different voltages was carried out, and the A-weighted sound pressure level (A-SPL) and its spectrum characteristics with different surface field strength and different altitude were obtained. The experimental results show that, with the increase of altitude, the A-SPL of HVDC transmission line presents a non-linear change rule, and the increasing trend gradually slows down at higher altitude. The frequency components of the corona-generated AN from the transmission line at the high altitude area were mainly concentrated in the frequency range of 2000 to 20000 Hz. The altitude correction law of single frequency sound pressure level in the range of 2~2.5 kHz and 5~8 kHz is in good agreement with that of A-SPL, and 5~8kHz frequency band has stronger anti background interference ability. In the frequency range of 5~8 kHz, the difference between A-SPL and single frequency noise component is about 8.0~10.6 dB. When the background noise is large, the A-SPL of HVDC transmission line and its altitude correction law can be obtained by analyzing the sound pressure level of single frequency. © 2020 Chin.
