基于Python软件的故障录波数据分析

Analysis of Fault Recording Data Based on Python

随着数字式继电保护的大量推广使用,继电保护的可靠性与灵敏性得到了提升,而其中的故障录波器是提升电力系统安全运行水平的重要自动装置。以一个基于PSCAD/EMTDC软件仿真的故障案例说明利用Python软件可以进行故障录波文件读取与精确定量分析,为保护动作判断提供重要依据。

With the extensive application of digital relay protection,the reliability and sensitivity of relay protection are improved,and the fault recorder is an important automatic device to improve the safe operation of power system.In this paper,a fault case based on PSCAD/EMTDC software simulation shows that Python software can be used to read and accurately analyze the fault recording file,which provides an important basis for the judgment of protection action.
