摘　　要：在分析计算磁阀式可控电抗器(MCR)的特性时,必须考虑交、直流共同激励和铁芯磁路各部分磁化状态不同的特点。提出了基于Jiles-Atherton逆模型的MCR等效磁化特性模型,该模型考虑了磁滞、直流偏磁和小截面磁阀等因素对磁化特性的影响,适用于不同结构参数下的MCR;基于等效磁化特性模型提出了MCR电流特性、控制特性和损耗特性的计算公式和方法;针对一个MCR样机进行了理论计算和实验测量,同时与基于理想小斜率模型的计算结果进行了对比。结果表明,提出的MCR等效磁化特性模型及其电流特性、控制特性和损耗特性计算方法是正确有效的,对MCR的工程设计计算有一定的参考和指导意义。In the calculation and analysis of the characteristics of the MCR（ Magnetic-valve Controllable Reactor）,it is necessary to consider the characteristics of both AC and DC excitation and different magnetization states of the core magnetic circuit. Firstly,an equivalent magnetization characteristic model of MCR based on inverse JilesAtherton model is proposed. This model considers the effects of hysteresis,DC magnetic bias and small section magnetic-valve on the magnetization characteristics,and it is suitable for MCR with different structural parameters. Subsequently,the calculating formulas and methods for current characteristics,control characteristics and loss characteristics of MCR are proposed based on the equivalent magnetization model. Finally,the theoretical calculation and experimental measurement for a MCR prototype are carried out,and the results are compared with those based on the ideal small slope model. Test results indicate that the proposed MCR equivalent magnetization characteristic model and its current characteristic,control characteristic and loss characteristic calculation method are correct and effective,which provides a certain reference and guidance for engineering design and calculation of MCR.
