摘要
介绍了一种新型自动跟踪补偿消弧线圈,其主体结构为带有第三绕组的自耦变压器,通过对第二、三绕组的控制实现消弧线圈的大范围连续可调。利用M atlab仿真平台建立了这种消弧线圈的数字仿真模型,对其性能进行了仿真分析。通过查表的方式来确定消弧线圈第二、三绕组的控制参数,采用线性插值的方式建立了相应的表格。综合仿真进一步验证了这种消弧线圈具有大范围连续可调、谐波含量小、不含有机械运动部件,免除了因机械运动而造成的故障、噪音等诸多优点。
A new structure arc-extinguishing reactor （AER） is introduced. Its main structure is a auto-transformer with a tertiary winding. Continuous adjustment of AER with large scale can be implemented by joint control on secondary and tertiary windings. The digital simulation model of AER is established based on Matlab/simulink and the simulation analysis based on this model is studied. The equivalent fundamental reactor of the AER can be determined by looking up tables, which are established by simulation. Integrated simulation proves further that the new structure AER has much superiority compared with existed AER such as continuous adjustment with large scale, low harmonic content, low noise and no mechanical parts and so on.
