| 摘 要： | 为研究地电位升高时超高压交流输电线路产生的工频电场,将地电位升高作为第一类边界条件,应用模拟电荷法,建立了考虑地电位升高影响的超高压交流输电线路下方工频电场计算模型。与CDEGS软件计算结果的对比表明,该方法是可行、有效的。同时分析了不同地电位升高值、导线高度及导线排列方式下,地电位升高对超高压输电线路工频电场的影响。提出对地电位升高区域内的工频电场暴露应给予更多关注并采取相应的限制措施。

| Abstract: | In order to study the power frequency electric field caused by UHV-AC transmission line as ground potential rise(GPR) occurs,a model for calculating power frequency electric field strength under the UHV-AC transmission line is established by using charge simulation method which takes GPR as the first boundary condition.The model considers the influence of GPR.The comparison of calculation results between this method and the software CDEGS shows the former is feasible and effective.Moreover,the influences of... |
