| 摘 要： | 淮南至上海特高压交流输电示范工程是我国首条百万伏输电线路工程，该工程部分勘测线路要经过嘉山地震台地电观测区外南侧。利用拟蒙特卡罗数值积分方法计算在输电线路两侧由线路工作电流激发的工频电场，将计算结果分别与地电场和地电阻率观测时允许的工频骚扰电场强度进行比较，得到不同电压等级、不同塔型的交流输电线路在典型工作电流下不影响嘉山地震台地电观测的最小允许距离。

| Abstract: | The Huainan-Shanghai supreme Hiter high pressure alternating current transmission demonstration project is our country first 1 million conceding electric wire projects.Some survey lines of this proj ect pass though the outside of terrace electronic resistivity observa-tion and electricity field observation area of Jiashan Seismic Station in the south.Using the Quasi-Monte Carlo numerical integral method,the power frequency electric field stimulate by work electric current of the transmission line are calculated.Comparing the computed result with allowable interferential eletric field intensity of power frequency of place electric field and earth-resistivity observation,the minimal allowable distances that will no affected on the terrestrial electricity observation at Jiajing station for different voltage level and different type of tower,as well as with typical power current on the transsmission line,are obtained. |
