常用遥信的误报、漏报都是由于硬件结构上的局限造成的。即:采集的遥信都是硬接点的信号,这些信号是先经遥信转接屏再接入RTU屏的。信号告警多次发生漏报和误报现象,给保证电网运行安全带来了一定的困难。经过长期对误报、漏报的报警信号进行统计分析,对产生这类问题的原因提出了几点看法。 Commonly used remote signal false positives, omissions are due to the limitations of the hardware structure caused. That is: the acquisition of the remote signal is the signal of the hard contact, these signals are first by the remote access screen then access the RTU screen. Repeated failure of signal alarm and false alarm phenomenon occur, to ensure the safety of power grid operation has brought some difficulties. After a long time on the false alarm, omission of the alarm signal for statistical analysis of the reasons for such problems raised a few observations.
