Magnetic saturation reactor winding current analysis

电抗器绕组电流分析计算是磁饱和式可控电抗器实际设计研究中值得关注的问题。根据磁饱和式可控电抗器的磁饱和特性,通过对等效电路的分析,当触发角在0。导通时,电抗器容量最大,各绕组流过的电流最大,找到了电抗器绕组电流计算的定量关系。通过MATLAB进行实例仿真,结果说明电流计算公式正确;根据各绕组电流有效值的不同,其分析结果可用于指导实际设计过程绕组线径的选型。

It is a concern research that the reactor winding current calculation is magnetically saturated controllable reactor de- sign. According to the saturation characteristics of magnetically-saturated controllable reactor,and by analyzing the equivalent cir- cuit, When the value of trigger angle is 0＇, then the capacity of the reactor and winding current will be maximal, the quantitative rela- tionship of winding current is obtained.Through simulation model based on MATLAB, Results show that the current formula is cor- rect. and according to the different winding current effective value, the analysis results can be used to guide the selection of the actu- al design process of winding wire diameter.
