随着特高压直流输电线路的建设,地面电场测量系统的使用越来越广泛。然而,线路周边复杂的电磁环境导致电场测量系统面临着严峻的电磁兼容性问题。基于电场测量系统的原理和结构,结合实际工作情况,实现了屏蔽、接地、滤波及隔离等电磁兼容性设计。最后,通过辐射发射试验、传导发射试验、辐射抗扰度试验、磁场类抗扰度试验、静电放电抗扰度试验及电快速瞬变脉冲群抗扰度试验验证了电场测量系统电磁兼容性设计的有效性。

英文摘要：

With the construction of the ultra high voltage direct current（ UHVDC） transmission lines,the ground electric field measurement system is more and more widely used. However,the complex electromagnetic environment of UHVDC transmission lines around the circuit results in the systems facing the grim problem of electromagnetic compatibility. Based on the principle and structure of the electric field measurement system,combining with the actual working situation,the shielding,grounding,wave filtering,isolation and other electromagnetic design are realized. Finally,by using radiation emission test,conducted emission test,radiation immunity test,magnetic field immunity tests,electrostatic discharge immunity test and electrical fast transient immunity test,this paper verifies effectiveness of the electromagnetic compatibility design of the electrical field measurement system.
