摘　　要：设计了一台牵引变电站27.5 kV/2000 kVA单相磁阀式可控电抗器。磁阀式可控电抗器响应速度加快会增加成本或损耗,同时会产生大量谐波,严重影响电能质量,使其在牵引变电站的应用受到限制。为此提出了一种快速响应和谐波抑制的方案,并运用Maxwell和MATLAB软件进行仿真验证。最后,制作一台27.5 kV/2000 kVA的单相油浸磁阀式可控电抗器样机,并进行了测试,结果表明运用该方案设计出的磁阀式可控电抗器具有响应快速和谐波含量低的优点。A 27.5 kV/2000 kVA single-phase magnetic-valve controllable reactor for traction substation is designed.The faster response speed of the magnetic-valve controllable reactor will increase the cost or loss. At the same time, it generates a lot of harmonics, which seriously affect the power quality and limit its application in the traction substation. A fast response and harmonic suppression program is proposed, and the Maxwell and MATLAB software are used for simulation verification. Finally, a 27.5 kV/2000 kVA single-phase oil-immersed magnetic-valve controllable reactor prototype was produced and tested. The results show that the magnetic valve controllable reactor designed by this scheme has the advantages of fast response and low harmonic content.
