摘　　要：采用现场实测和仿真计算相结合的方法,研究±500 kV直流架空线路地面合成电场及离子流密度的分布规律,并讨论相关参数的设定问题,验证基于Deutsch假设的解析计算法的工程实用性,为特/超高压直流输电线路的初步设计、环境影响评价、竣工环保验收等环节提供技术支持。The distribution rules of total electric field and ion current density at ground level of ± 500 kV HVDC Lines are investigated through combination of test and simulation methods,and the simulation parameters are also discussed. The field test result is consistent with the result of simulation,so the engineering probability of analytic calculation method based on Deutsch method has been verified. The Deutsch method can provide technical support in preliminary design, environmental impact assessment and environmental protection acceptance of HVDC transmission lines.
