摘　　要：为解决双绕组Dyn联结的晶闸管控制变压器型可控电抗器设备产生的5、7次谐波大的问题,以实现设备的良好应用,笔者采用双二次绕组控制模式,通过移相方式抵消设备产生的5、7次谐波,并搭建试验电路对其进行验证。结果表明,该接线方式对5、7次谐波抵消率在90%以上,能确保设备的经济运行。In this paper,for solving the 5^th and 7^th harmonics generated by the TCT（ thyristor controled transformer） type adjustable reactor of Dyn connection and achieving good application of the equipment,the double secondary winding control mode is used to offset the 5^th and 7^th harmonics generated by the equipment by way of phase shift. And test circuit is set up for validation. It is shown by the result that the elimination ratio of the 5^th and 7^th harmonics in the double secondary winding is above 90% , which assures economic operation of the equipment.
