摘要
紧凑型线路具有大幅度提高输电线路自然功率、减小线路走廊和改善工频电磁场环境等优点,目前已经在全国范围内逐步推广。基于Ansys对高海拔500 kV紧凑型和常规型线路进行电场环境仿真分析,并与现场测试数据对比分析,结果表明高海拔紧凑型线路线下电场环境大大优于常规线路,表面最大场强、电晕起始场强略大于常规线路,有限元分析能有效仿真输电线路电场环境。
The compact transmission fine has many advantages that can greatly improve natural power, to reduce lines corridor and improve the environment of power frequency electromagnetic fields etc. At present the compact transmis-sion line is being implemented on a national scale. This paper based on Ansys to simulate the electric field of high al- titude 500 kV compact transmission line and conventional transmission line, and compare with the field test data. The results show that electric field environment of compact transmission line superior to conventional transmission line, the maximum surface of the field and the corona inception field strength slightly more than compact transmission fine, and the finite-element analysis can effectively simulate electric field of transmission line.
