三相三线电能表常见接线模式的智能化识别

Intelligent Identification of Three-Phase and Three-Wire Watt-Hour Meter Common Connection Mode

提出了适用于电能表现场校验仪的三相三线电能表常见接线模式的智能化分层识别方法。该方法首先根据电流相位argIc^＊／Ia^＊特征把48种常见接线模式分为4大组，其次根据线电压相位argUcb^＊／Uab^＊特征把每大组12种接线模式均分为2个小组，再根据电压与电流相位argUa^＊／Ia^＊特征对每一小组6种接线模式进行识别，该方法已成功地应用于相关产品的开发及生产过程中。

The intelligent identification method of three-phase and three-wire watt-hour meter common connection mode is proposed. First of all, 48 common mode can be classified to 4 big groups, according to the character of argIc^＊/Ia^＊. Secondly, in the light of the character of argUcb^＊/Uab^＊ , each group including 12 models can be divided into 2 little groups. Thirdly, based on the character of arg Ua^＊/Ia^＊ , 6 wire connection modes of each group are identified. It is proved to be successful in the process of relative production development.
