摘　　要：提出了一种基于TCR模块、无需附加滤波设备的可控电抗器拓扑。它通过Y/Y/△三绕组变压器接入中、高压系统,低压侧采用双绕组结构,接有多组三角形接线的TCR模块。此拓扑注入系统的谐波电流极小,在电抗器整个运行方式下不需任何滤波装置便能达到国家标准,具有常规TCR的所有功能且占地面积小,损耗低,控制保护易实现,可靠性高,冷却系统容易实现。基于EMTDC/PSCAD的仿真研究证明该系统谐波特性好,无需附加滤波设备。This paper puts forward a novel topology of controllable reactor, the structure is based on many small capacity thyristors controlled reactor （TCR） modules and a Y/Y/A three-windings transformer connecting to system. The HV and LV side of transformer adopts duplex winding structure and each has multi-bank TCR modules in delta connection. In this topology, the harmonic current injected into the power system is very small. It not only possesses all the functions a traditional TCR has, but also has many other merits such as occupying small floor space, generating little loss, easy implementation of control and protection scheme, and high reliability etc. A 500 kvar industrial prototype is under construction in Langfang, Hebei province of P. R. China. Digital simulation based on EMTDC/PSCAD is carried out to verify the perfect harmonics characteristics of topology proposed.
