| 摘要: |
| 目前，电力变压器与磁控电抗器这两种设备都是分别制造，这两种设备分别有各自的铁芯，占用面积比较大。提出一种双功能变压器，用一台磁控电抗器的铁芯，同时实现变压器与磁控电抗器两种功能。双功能变压器占用面积比较小。用Matlab仿真软件中的Simulink工具箱构建双功能变压器仿真模型，对双功能变压器进行仿真分析。结果表明:不论变压器铁芯饱和度的变化是多少，引起变压器漏抗的变化不大于7%。提出的双功能变压器可同时实现变压器与磁控电抗器两种功能。变压器模块运行对磁控电抗器模块工作影响很小；磁控电抗器模块运行对变压器模块工作影响很小。 |

| Abstract: |
| At present, the power transformer and the magnetically controllable reactor (MCR) are manufactured respectively, two devices have their own core respectively. Two devices occupied area is larger. The double function transformer which realizes the transformer and MCR two functions with a MCR core is proposed. The double function transformer occupied area is small. A simulation model based on MATLAB/Simulink is built and the double function transformer is simulated. The results show that no matter how much the change of the transformer core saturation is, the change of the transformer leakage reactance caused by it is not greater than 7%. The proposed double function transformer can realize transformer and MCR two functions at the same time. Transformer module operation has little impact on MCR module work; little impact on the transformer module working caused by MCR module run. |
