摘要

本论文以供区进一步应用的智能计量装置为研究重点，实现了一种电表箱计量误差分析方法和供区高效电拓扑识别方案。通过开关的查表、抄表和测量功能，实现了仪表箱中总表与子表的对应关系，建立了测量值与异常系数相关的矩阵方程。通过求解各分表的异常系数来支持对仪表不准确或窃电行为的分析。考虑到电气拓扑识别的效率，提出了一种电压畸变和特征电流识别方案，实现了变电站区域内子节点的快速识别，无需终端存档。

An intelligent measuring device and its function realization method for deepening application in substation

This thesis focuses on the intelligent measuring device for further application of power supply district, which realizes an analysis method of meter measurement error in the electricity meter box and an efficient electrical topology identification scheme in power supply district. Through the meter search, reading and measurement functions of the switches, the corresponding relationship between the total meter and the sub meter in the meter box is realized, and a matrix equation related to the measurement value and the abnormal coefficient is established. The analysis of meter inaccuracy or power theft behavior is supported by solving the abnormal coefficient of each sub meter. In view of the efficiency of electrical topology identification, a voltage distortion and characteristic current identification scheme is proposed to realize the rapid identification of sub nodes in the substation area without the archives of the terminal.
