摘要
基于SCADA/EMS系统实时采集和处理电网数据的基础上,实现负荷实测与网损的在线计算。每隔5分钟实现一次负荷实测与电网元件负载率、容载比等指标的计算与统计,并将这种计算与统计指标推广至整年月,从而准确反映电网元件的负载情况与运行水平。每隔5分钟实现一次电网的在线网损计算,从而累加获得电网每日的电能量损耗,并实现与电能量采集系统网损电量的校核。通过实际应用表明,基于SCADA/EMS系统的负荷实测与网损在线计算能为电网运行人员提供有益的指导,具有较高的实际价值。
Based on SCADA/EMS system,power load measurement and on-line power network loss compute can be realized.Power load measurement,power load ratio and capacity-load ratio of power network equipment can be calculated and stated for every five minutes.Power load ratio and operation state of power network equipment can be reflected by the year or month calculated and stated result of those indexes.On-line power network loss compute can be realized for every five minutes.Based on on-line power network loss compute,power network loss quantity can be got to revise power network loss quantity by electrical energy gather system.It is indicated that helpful guidance can be provided for power system personnel through practical operation and application.
