特高压直流输电线路工频参数测试干扰水平仿真分析

摘要

通过分析特高压直流输电线路并行线路运行工况,综合考虑输电线路沿线地理环境、相序、塔型、导线架设方式、土壤电阻率等因素,对扎鲁特—青州特高压直流输电线路工频参数测试的干扰水平进行仿真计算,为特高压直流输电线路工频参数测试方案制定提供参考,保障了该线路工频参数测试人员及设备的安全.%By analyzing operating conditions of the parallel lines near the UHVDC transmission line,considering the geographical environment,phase sequence,tower type,wire erection mode,soil resistivity and other related factors,the interference level of the power-frequency parameter measurement for the Zhalute-Qingzhou UHVDC transmission line is calculated.The calculation results can help providing a theoretical guidance for the power-frequency parameter measurement scheme and guarantee the safety of personnel and equipment.
