摘　　要：为了研究单磁芯饱和电抗器的控制输出特性,在单磁芯结构中增加一个检测绕组。利用多项式和双曲线混合模型拟合了磁芯磁化曲线,基于M ATLAB软件建立仿真模型并制成了电抗器实验装置。当交流激励使饱和电抗器处于饱和状态时,研究检测绕组感应电压峰值、有效值与直流偏磁磁势之间的关系曲线,并绘制控制输出特性。仿真和实验表明,该模型很好地反映了饱和电抗器的控制输出特性,有利于优化饱和电抗器参数,可快速设计实验方案。A measurement winding is added to study the control-output characteristics of the single core saturable reactor. Magnetization curve of the core is fitted using polynomial and hyperbola hybrid model. Its simulation model on MATLAB as well as the experimental device is achieved. The control- output characteristics are obtained by studying the relationship between inductive voltage and DC magnetic potential when AC stimulation makes it saturated. Simulation and experimental results verify the feasibility of the proposed model, which is useful for optimizing the reactor parameters and designing experiment scheme promptly.
