    摘 要:工程应用中合并单元和数字化电能表之间参数不一致造成的计量系统误差超差、数据无法上传等故障较为常见。介绍了现有的变电站数字化电能计量系统的参数一致性研究内容,归纳得出工程应用现场发生的三种设备参数不一致类型,对各项参数不一致类型进行正向分析,得到相应的故障表征现象,包括电能、电压、电流等数值异常表征。结合工程实际选取故障表征值,确立相应的诊断表格。基于故障表征值获取方式和诊断表格设计了一种适用于半数字化计量体系的诊断方法,并通过试验验证了方法的有效性。该诊断方法能够通过故障现象反向诊断参数不一致的具体原因,加快工程应用现场设备参数不一致导致的故障排除速度。

    Abstract: The situations of system errors and data updating failure exist in engineering applications. The non-consistent parameters between the merging unit and the digital electric energy meter cause these situations. This paper introduced the content of the consistency parameters of the digital measurement system in substations to conclude three different types of the non-consistent parameters of this kind of equipment in the engineering application field. This research analyzed the non-consistent parameters and obtained the fault representation phenomenon, including abnormal numerical representations of electric energy, voltage, and current. This study established a diagnosis form by choosing the fault characterization value in engineering practice. A method of diagnosis suitable for a semi-digital measurement system was designed based on the acquisition method of fault characteristic value and diagnosis form. Experiments proved the effectiveness of this method. This diagnosis method can reverse diagnose the specific causes of a non-consistent parameters by using fault phenomena. Therefore,accelerate the troubleshooting speed caused by non-consistent equipment parameters in the engineering application field.
    Key words: digital energy metering; parameter non-consistent type; fault characterization value; parameter consistency diagnosis form;parameter consistency diagnosis method
