摘要

高压直流输电的快速发展使得平波电抗器成为换流站电磁污染的主要来源。为降低平波电抗器周围的空间磁场

对胶东±660 kV换流变电站满负荷运行条件下极母线平波电抗器的空间磁感应强度进行测量得到平波电抗器实际的磁感应强度分布

通过数据处理消除了地磁场对测试数据的明显影响

建立了平波电抗器在静磁场下的磁场分布模型并结合测量数据验证了计算模型的准确性。最终提出了几种磁场屏蔽方案

通过比较不同材料、尺寸及位置下屏蔽体的屏蔽效果的比较

得出了最优的屏蔽体架设方案。

Abstract

With the rapid development of UHVDC transmission

air-core smoothing reactor has become the main source of electromagnetic contamination in converter substations. To reduce the spatial magnetic field around the smoothing reactor

the actual magnetic field distribution is obtained by measuring the magnetic induction intensity to the south

north and west of the smoothing reactor in Jiaodong ±660 kV converter substation. Through data process

the effect of the geomagnetic field on the magnetic field distribution of smoothing reactors is analyzed and compared with the simulation result

which verified the calculation model. Magnetic shielding measures are proposed by comparing the shielding effects of different materials

sizes and positions

the optimal shielding erection scheme is finally proposed.
