建立准确反映磁控电抗器动、静态特性的数学模型对提高应用场景下对象的控制性能具有重要意义。在已知磁控电抗器的结构、材料、电压等级和容量的前提下,使用Ansoft Maxwell与Simplorer软件平台,通过场路耦合等多物理域联合计算,给出了一种通用的磁控电抗器建模方法。该方法不仅能准确得到磁控电抗器的静态特性,而且能通过各工作点下的阶跃响应得到电抗器的动态特性。算例结果表明,建模过程按步骤操作,建模结果准确,可以使用简单控制方法实现控制目标,控制效果好。

It is of great significance to establish a mathematical model to accurately reflect the dynamic and static characteristics of the magnetically controlled reactor(MCR)for improving the control performance of the object under application scenarios.On the premise that the structure,material,voltage level and capacity of the MCR are known,a general modeling of the MCR was presented by using Ansoft Maxwell and Simplorer software platform and combined calculation of field path coupling and other physical domains.This method can not only accurately obtain the static characteristics of the MCR,but also obtain the dynamic characteristics of the reactor by the step response at each operating point.Numerical examples show that the modeling process is operated by steps and the modeling results are accurate.Simple control methods can be used to achieve the control objectives and the control effect is good.
