摘要
以糯扎渡电站送电广东±800 kV特高压直流输电工程为背景,对换流站绝缘配合进行了研究。在分析换流站各种过电压的基础上,基于高压直流输电换流站绝缘配合原则,提出了避雷器配置方案和换流站绝缘水平。同时,根据换流站设备的操作冲击耐受电压,计算出了换流站阀厅空气净距。文中的研究结果可为以后直流输电工程的设计和建设提供参考。
Based on the background of the Nuozhadu-Guangdong ±800 kV ultra high voltage direct current power transmission system, the insulation coordination of converter station is researched. On the basis of analysis on all kinds of overvoltage, according to the converter station insulation coordination principle of high voltage direct current power transmission, arrester configuration scheme and insulation level of converter station are proposed. At the same time, according to the converter station equipment switching impulse withstand voltage, the converter station valve hall air clearance is calculated. The research results of this paper may provide reference for design and construction of the direct current power transmission system in the future.
