变电站母线电压越限告警信息量问题的分析及处理

摘要

通过监控信息量现状分析，找出了造成变电站母线电压越限告警信息量大的主要原因，针对性地提出了建立集中监控专家处理系统、建立电压越限预处理模型两种解决方案，并通过对比确定了采用电压越限预处理模型，方案实施效果表明，采用该模型后，降低了变电站母线电压越限告警信息量，提高了监控效率，保证了电网安全可靠运行。%After the status quo of monitoring information amount was analyzed, this paper found out the main reasons of out-of-limit alarm informa-tion amount of bus voltage in substation, raised two kinds of solutions about the centralized monitoring expert processing system and voltage out-of-limit pretreatment model, and determined the voltage out-of-limit pretreatment model via comparison. The plan implementation results show that after the model is used, the out-of-limit alarm information amount of bus voltage in substation is greatly reduced, which improves the monitoring efficiency and guarantees the safe and reliable operation of power grid.
