摘　　要：在距离保护中,根据发生故障的特征判别出故障的类型和发生故障的相别,准确找到故障环,可以使测量元件更加精确地反映出故障点的距离。文中使用MATLAB/Simulink仿真软件进行建模仿真,设置在具有零序电流故障和过渡电阻的影响下,阻抗继电器的动作情况,通过输出的相角等数据,对阻抗继电器的动作特性进行学习研究。In distance protection,according to the characteristics of the fault,the fault types and fault phases are distinguished,and the fault ring is found accurately,which can make the measuring element more accurately reflect the distance of the fault point.In this paper,MATLAB/Simulink simulation software was used for modeling and simulation.The operation of the impedance relay was studied under the influence of zero sequence current fault and transition resistance,and the operating characteristics of the impedance relay were studied by the output phase angle and other data.
