摘　　要：针对单个控制绕组的变压器式可控电抗器(controllable reactor of transformer type,CRT),分析了其带LC滤波器谐波抑制绕组的两种布置方式:谐波抑制绕组置于工作绕组与控制绕组之间,以及控制绕组置于工作绕组与谐波抑制绕组之间。通过对两种布置方式绕组间短路电抗、等效电路以及谐波等效电路的分析表明,谐波抑制绕组置于工作绕组与控制绕组之间时,对CRT谐波抑制效果较好。建立了带谐波抑制绕组CRT的MATLAB仿真模型,对谐波抑制效果进行了仿真分析,验证了绕组布置分析的结果。Two kinds of different arrangements on harmonic-suppressed winding with LC filters are analyzed on the basis of the principle of controllable reactor of transformer type（CRT） with simplex control winding. Harmonic- suppressed winding may be placed between working winding and controlling winding, and the controlling winding may be placed either between working winding and harmonic-suppressed winding. The theoretical analysis of the short circuit reactance of two different arrangements and the harmonic equivalent circuit of three-winding transform- er reveals that the effect of harmonic-suppressed winding is optimum when the harmonic-suppressed winding is placed between working winding and controlling winding. The MATLAB model of CRT with harmonic-suppressed winding is established. It is revealed that the analysis results of winding arrangement are consistent with simulation ones, and the designed CRT has better performance.
