To solve this problem, a decoupling operation mode and its implementation scheme are presented, based on the idea of the multi-winding working mode. First, in accordance with the characteristics of the decoupling operation mode, the required current-limiting inductances are calculated, while the rated values of the winding current are given. Second, in accordance with the rated value of the current for each control winding, the regulating range is graded, and then the current of every control winding is discretized discretized in each grade. Third, based on the mathematical model for calculating the values of the winding current of a CRT, all discrete points are calculated step-by-step, and then the trigger angle regulating rule, which makes the control winding current constant after meeting the rated value, is obtained. Finally, a simulation experiment is conducted, by employing a CRT, for which the control windings rated values for the current are 9.16, 11.59, 24.52, 51.85 A, and 109.64 A respectively. The results show that the values of the control winding current are maintained at their rated values under the decoupling operation mode %K 变压器式可控电抗器 %K 解耦 %K 工作模式 %K 数学模型 %K 电流控制 %K < %K br> %K controllable reactor of transformer type %K decoupling %K operation modes %K mathematical models %K current control %U http://manu19.magtech.com.cn/Jweb_xnjd/CN/abstract/abstract12604.shtml
