摘 要:電能計量工作作為電力企業生產電能過程中最重要的一個環節,直接影響著電力企業的經濟效益。而關口電能表對于整個電網的電能計量同樣有著非常重要的作用。關口電能表的主要有兩個功能,一為貿易結算,二為內部經濟指標的考核。因為關口電能表涉及到的電量比較大,所以關口電能表運行的安全性和穩定性會對計量貿易的結算的公平性以及公正性產生較大影響。在關口電能表的實際應用中,會存在著一些異常問題,例如關口電能表的數據出現異常,影響所欠電費的正常追收等,而本文則重點介紹了關口電能表數據異常的電量追補計算過程。
關鍵詞:關口電能表;數據異常;電能計量

Abstract:Electric energy measurement is the most important link in the process of producing electric energy in electric power enterprises,which directly affects the economic benefits of electric power enterprises. The gateway energy meter also plays a very important role in the whole grid's energy metering. The main function of the gateway watt-hour meter has two functions,one is trade settlement,the other is the assessment of internal economic indicators. Because the power meter involves a large amount of electricity,the safety and stability of the operation of the meter will have a great impact on the fairness and impartiality of the measurement trade settlement. However,there will be some abnormal problems in the practical application of the power meter,such as the abnormal data of the power meter,which affects the normal recovery of the electric charge. This paper focuses on the calculation of abnormal power consumption in gateway energy meter.
Keywords:grid energy meter;abnormal;analysis and processing
1 關口電量采集系統的基本構成
可門電廠側在GIS繼保室設置關口計量屏,接入福門Ⅰ路5011/5012計量點主副關口電能表、福門Ⅱ路5032/5033計量點主副關口電能表、01高壓備變5021計量點主副關口電能表、02高壓備變5053計量點主副關口電能表,以及4臺主變輔助計量點關口電能表。各個計量點的關口電能表通過485接口接入FFC電量采集器,再調度數據網Ⅱ區接入省調電能量計量系統。電量系統后臺每15min自動記錄一次全部數據,FFC電量采集器的數據保存期為3個月以上。關口電量采集系統的基本構成如圖1所示。
可門電廠側設有發電上網關口計量點福門Ⅰ路5011/5012(在對側500kV福州變設有考核計量點福門Ⅰ路5041/5042),以上計量點均接入省調電能量計量系統的電量數據采集器?!?br>
