摘　　要：平波电抗器作为高压换流站的重要设备,其周围的电磁环境日益受到关注.依据某换流站中±800 k V斜撑式干式平波电抗器的结构特点和现场布置情况建立了三维电场仿真模型,应用有限元法研究了平波电抗器纵切面上的电场分布、距离地面1.5 m高的水平面上电场分布和主母线及均压环表面电场值.研究结果表明空间中最大场强出现在中间主母线下方均压环外表面,1.5 m高平面上距离平波电抗器中心10 m以外的区域电场值均小于30k V/m.本研究为平波电抗器电磁环境的评估及其结构的优化提供了参考.As an important device in the high-voltage converter station,the smoothing reactor’s electromagnetic environment is paid more and more attention.A three-dimensional electric field simulation model is established according to the structural features and site layout of the ± 800 k V oblique dry-type smoothing reactor in the converter station.This paper studies the electric field distribution in the longitudinal plane of the smoothing reactor and in the plane 1.5 m high from the ground,and the surface electric field values of main bus and grading rings through the finite element method.The results show that the maximum electric field strength appears outside the grading ring under the middle main bus; and the electric field values are all less than 30 k V / m for the area more than 10 meters away from the center of the smoothing reactor in 1.5 m plane over ground.The results provide the reference for electromagnetic environment assessment and structural optimization of the smoothing reactor.
