| 摘 要： | 为评估超高压交流输电线路跨越农业大棚区的电磁环境,对辽宁省境内500kV交流输电线路跨越农业大棚区的工频电场强度和磁感应强度进行了现场测量,然后基于模拟电荷法、模拟电流法原理编制了可计算各种交流输电线路下方工频电磁场分布的软件包,最后应用此软件计算了农业大棚区的工频电磁场强度并与现场测量结果进行了比较。结果表明,农业大棚区的工频电场和工频磁场现场测量值均未超过标准规定的10kV/m和0.1mT;农业大棚对电场分布产生了一定的影响,但对工频磁场影响不大;对于农业大棚区的工频电场和工频磁场,数值计算结果与现场测量结果规律所呈现的基本一致。工频电磁场计算软件可为高压交流输电线路跨越农业大棚区的电磁环境评估提供参考。 |

| Abstract: | To assess electromagnetic environment of EHV AC transmission lines across the agricultural greenhouses,power frequency electromagnetic field of 500kV EHV AC transmission lines across the agricultural greenhouses in LiaoNing province is measured.Then,a software package on calculating of electromagnetic field for various AC transmission lines is developed based on charge simulation method and current simulation method.Finally,power frequency electromagnetic field of Agricultural Greenhouses is calculated by this package,and the results are compared with that of field measurement.The results show that power frequency electromagnetic field of agricultural greenhouses meet the requirements of standard(10kV/m and 0.1mT).And the greenhouse has a larger impact on electric field than magnetic field.In addition,the calculated result is consistent with that of field measurement as to the electromagnetic field of agricultural greenhouses.Accordingly,the software package can provide reference for electromagnetic environment assessment for HVAC transmission lines across the agricultural greenhouses. |
