摘要
为解决高海拔特高压直流输电线路电磁环境(EME)特性、预测与防护等问题,依托特高压工程技术(昆明)国家工程实验室,建立了首个高海拔特高压直流线路电磁环境测试平台,开展了长达6 a的试验研究,获得了直流线路电磁环境参数特性规律;得到了可听噪声为1 d B/1 000 m、无线电干扰场强为4.3 d B/1 000 m的海拔修正系数,提出了考虑气象参数的直流线路无线电干扰和可听噪声的预测式,并开展了±800 k V楚穗直流线路实测对比;提出了改善线路下方地面合成场强的引流屏蔽措施,可使其最大值降低50%。
In order to study the electromagnetic environment(EME) characteristics,prediction,and protection of UHVDC transmission line in high altitude area,in Kunming UHV national engineering laboratory,first,we established an EME testing platform of UHVDC transmission line in high altitude area,and obtained EME characteristics during experimental studies for six years.Then,we derived the altitude correction factors of the audible noise of 1 d B/1 000 m and radio interference of 4.3 dB/1 000 m,and put forward a prediction formula of radio interference strength and audible noise considering meteorological parameters.Finally,we measured the EME of the ±800 kV Chu-Sui DC transmission line for contrast,and proposed the drainage shielding methods to reduce the maximum of ground electric field strength to 50%.
