摘要
在目前电网继电保护自投装置的改造中 ,微机保护得到了广泛的应用 ,它解决了电磁型保护存在的一些问题。为此分析 LFP-965系列微机自投装置在实际应用中怎样配置才能保证自投正确动作 ,并根据实践对原 V1 .0和 V1 .1版本提出了改进意见 ,升级到 V2 .0版本 ,使备自投得到了进一步完善。经过实践证明自投配置是成功的 ,并且创造了较大的经济效益。
In renovation of network relay protection automatic closing device,computer-based protection is widely used,which resolved the problems with electromagnetic relay protection.This paper made a research on the configuration of LFP-965 series microcomputer-based automatic closing equipment in practical application to ensure the proper closing.V1.0 and V1.1 are upgraded to V2.0 based on the improvement proposal for V1.0 and V1.1.It is proved that automatic closing is successful,and great benefit is achieved.
