随着近年来电力行业规模的大幅度增加以及全国用电网络的完善,电力的应用也与人们生活的联系越来越紧密，同时关于输电线路电磁环境的问题和纠纷也接踵而来。而这些问题也对电力网络的持续完善造成了阻碍，从而对330kV高压输电线路的电磁环境各项参数进行深入研究和分析已经刻不容缓。 为了细致了解高压输电线路周围的电磁环境，本文对输电线路的四个主要电磁环境参数：电场、磁场、无线电干扰及可听噪声进行研究；并针对每项电磁参数在不同条件下的变化趋势进行分析，对其工程建设推荐的限定临界值进行推论和验证，最后选定适用于相应工程条件的符合设计规范要求的最佳方案。 论文基于‘陕西丰塬—张村330kV交流输电线路’工程，对线路的主要电磁环境参数进行详细的研究。另外对输电线路导线的表面场强、离子流密度及干扰参数等细致电磁参数也进行计算并与此工程实际测量的结果进行对比。在对输电导线的表面及线下电场的计算过程中，对模拟电荷法与逐步镜像法进行算法优劣性比较，对工频电磁场和无线电干扰参数及噪声的计算也选取了逐步镜像法和激发函数的方法。 通过针对电磁场、无线电干扰、可听噪声等各项电磁参数理论计算方法的研究，选取交流输电线路电磁环境综合计算的软件，在此基础上对不同输电线路高度、温度、湿度及导线排列方式条件下的线路电磁环境变化趋势进行仿真分析，最终与实际工程测量值进行比较分析，得出针对不同条件下使电磁污染达到最小值的最优线路设计方案。

With the increase in size of the electric power industry in recent years and the popularity of the national power, the application of the electric power also links with the people's life more and more close, but then on transmission line electromagnetic environment problems and disputes also ensue. And these problems on the popularization and development of electric power network caused some obstacles, to in-depth study and analysis on the electromagnetic environment parameters is urgent. To detailed understanding of electromagnetic environment around the high voltage transmission lines, in this paper, the four main electromagnetic environment of the transmission line parameters: the electric field, magnetic field and radio interference and audible noise are studied; And every change trend of electromagnetic parameters under different conditions were analyzed, and limit the critical value of the project construction recommend reasoning and validation, finally selected is suitable for the corresponding engineering conditions meet the requirements of the design specification of the best solutions. This paper is based on "shaanxi feng tableland, zhang village 330kv transmission line engineering, main electromagnetic environment parameters of circuit detailed research. In addition to the surface of the transmission line conductor field intensity and ion current density and meticulous electromagnetic parameters, such as interference parameters are calculated and compared with the results of actual measurement. On the surface of the transmission wire and off-line calculation of electric field in the process, the charge simulation method are compared with those of algorithm and method of image, the factory frequency electromagnetic field and radio interference parameter selection and the calculation of the noise and the corresponding calculation method. On the above theoretical calculation method of the electromagnetic parameters, choose a called ac transmission line electromagnetic environment integrated computation software, based on the different height of transmission line, temperature, humidity and under the condition of the wire arrangement line electromagnetic environment by simulating the change trend, finally comparing with actual engineering surveying value analysis, it is concluded that for make electromagnetic environment effects under different conditions to achieve the optimal solution of the minimum value.
