摘　　要：针对变电站电磁环境自动监测站布点方案普遍存在的效率不高、科学性不足等问题,以某500 kV变电站电磁环境自动监测站选址为例,通过建模仿真得到该变电站工频电场和工频磁场的空间分布,并实测验证了仿真结果的准确性。通过统计该变电站工频电场和工频磁场的空间分布特征,提出了基于变电站空间场强分布特征的自动监测站布点方案,建议优先在场强中位数分界线附近区域布点,以更好地反映变电站电磁环境。研究结果可指导变电站电磁环境自动监测站选址,提高变电站电磁环境监测布点的科学性,提升监测效率。In this paper,the location arrangement of electric and magnetic field automatic monitoring station on the substation is studied.The present method by manual monitoring is inefficiency and lack of science.Taking the location selection of automatic monitoring station for electromagnetic environment of a 500 kV substation as an example,the spatial distribution of power frequency electric and magnetic field of the substation is obtained by modeling and simulation,and the accuracy of the simulation results is verified by actual measurement.Based on the statistics of the spatial distribution characteristics of the power frequency electric and magnetic field of the substation,the layout scheme of automatic monitoring stations based on the distribution characteristics of the space field intensity of the substation is proposed.It is pointed out that the location near the median boundary of the field intensity should be prioritized to better reflect the electromagnetic environment of the substation.The research results can guide the selection of automatic monitoring stations for substation electromagnetic environment,improve the scientific location of substation electromagnetic environment monitoring and improve monitoring efficiency.
