摘　　要：论文介绍了晶闸管控制变压器(thyristor controlled transformer,TCT)型可调电抗器的原理,着重分析了低压绕组为三相四线接法的TCT工作过程及谐波特性。利用电磁暂态仿真软件PSCAD建立仿真模型,模拟装置的工作过程,得到不同触发角度时TCT注入系统电流的谐波特性,为设计该接线方式的TCT提供了重要参考,为进一步设计制造低谐波TCT打下了良好的基础。In this paper, the principle of thyristor controlled transformer （TCT）type adjustable reactor is introduced and the working process and harmonic characteristic of TCT with three-phase fourwire connection at LV winding. TCT simulation model is set up by the use of electromagnetic transient simulation software PSCAD to simulate operation process of the device, and obtain harmonic feature of system current injected by TCT at different trigging angle, which provides an important reference for design of the connection model of TCT and lays a good foundation for designing and manufacturing low harmonic TCT.
