摘要
现阶段,电力系统微机保护装置在电力系统输电线路、元件保护以及变电站综合自动化中应用较为广泛,能够为电力系统安全、稳定的运行提供一定的保障。但是,此装置在运行过程中存在电磁干扰情况,在干扰信号进入保护装置后,无法保证采集数据的准确性,且部分元件会受到不同程度的损伤。本文对电力系统微机保护装置干扰源及带来的影响进行分析,并提出了几点抗干扰措施。
At present, the application of power system microcomputer protection device in power system, transmission line protection device and integrated substation automation is more extensive, provide a guarantee for the safe and stable operation of power system. But this device has the electromagnetic interference in the operation process, the interference signal into the protection device after data acquisition accuracy can not be guaranteed, and components will be damaged in different degree, the paper carries on the analysis to the microcomputer protection device for power system interference and influence, then put forward some antiinterference measures.
