本文利用编写的MATLAB软件结合解析法证，分析了一种新型的接地距离继电器在系统振荡时再发生单相经过渡电阻接地短路时的动作特性。该接地距离继电器的动作判据是通过比较故障后测得的母线电压、补偿电压、零序电流和负序电流四个量的相位关系以确定继电器的动作行为情况 (In this paper, written in MATLAB software analysis and forensic analysis of a new type of ground distance relays in the system oscillation movement characteristics of single-phase transition resistance is shorted to ground. The operating criteria for the ground distance relay bus voltage is measured by comparing the failure, the phase relationship of offset voltage, zero sequence current and negative sequence current four amount to determine the relay actuation behavior )
