摘    要:高海拔地区特高压直流输电线路的电晕及其电磁环境问题已成为输电线路设计的瓶颈与最大障碍,而电晕引起的可听噪声(audible noise,NA)则是其主要制约因素之一。在高海拔地区经常伴随有各种情况的大风天气,其对可听噪声的影响不容忽视。本文依托特高压工程(昆明)国家工程实验室在海拔2 100 m处建设的,长800 m的双极直流试验线段,对可听噪声进行了长期的试验测量。通过将试验结果与理论分析相结合,初步研究了特高压直流线路可听噪声的特性,并着重分析了风速及风向对NA分布特性的影响。

关 键 词:特高压工程实验室  特高压直流  电磁环境  噪声  试验  高海拔

Abstract:Corona phenomenon and the corresponding electromagnetic environment have been the bottleneck and the biggest obstacle for the design of Ultra HVDC transmission line in high altitude area. The audible noise NA generated by the corona is one of the main restrict factor. In high altitude area it is always company with the strong wind weather, the influence of the which on the NA cannot be ignored. Based on the 800 m length bipolar test line which is build by National Engineering Laboratory for UHV Technology Kunming in the altitude 2100 m, measurement of the NA was carried out for a long term. Combining the measuring results and theory analyzing, this paper studied the characteristics of NA generated by the test line, and analyzed the influence of wind velocity and wind direction on the lateral profile.
Keywords:National Engineering Laboratory for UHV Technology  UHVDC  electromagnetic environment  audible noise  experiment  high altitude
