摘　　要：可控电抗器作为新型无功补偿设备能够有效地补偿电网无功、限制电网过电压及改善电能质量。高温超导可控电抗器因具有控制灵活、谐波含量低、可连续平滑调节、功率密度高等优点而受到广泛关注。文中研究了一种新型正交耦合型高温超导可控电抗器,其采用平行磁通控制以增大调节范围、垂直铁心结构以降低感应电压、增加气隙以降低谐波含量,介绍了该电抗器工作原理与基本结构,搭建了有限元分析模型,进行了380V小型样机的电磁设计,并分析获得其电抗调节范围及工作电流的谐波特性。结果表明,该新型超导电抗器具有很好的无功调节性能。As a new reactive power compensation equipment, controllable reactor can effectively compensate for reactive power, limit grid over - voltage and improve power quality. The HTS controllable reactor receives much concern for its advantages of flexible control, low harmonic, continuous smooth regulation and high power density. In this paper, a novel orthogonal flux coupled HTS controllable reactor was researched, which used parallel magnetic flux control to increase the range, used the verti- cal core structure to reduce the induced voltage, and added the air gap to reduce the harmonic. The working principle and basic structure of the reactor were introduced. The finite element analysis model was established. The electromagnetic design of the 380V small -scale prototype was conducted, and its output characteristics were obtained, such as reactance and harmonic char- acteristics of operating current. The results show that the novel HTS controllable reactor has good reactive power regulation per- formance.
