摘要

本文介绍了对印度国内某电站50天实时电能质量数据的分析。使用专用的PQ分析器收集数据。通过测量和分析，确定了不同电网扰动的程度，并与相关标准进行了比较。电压不平衡和个别电压谐波是主要的干扰。此外，通过记录这些负载绘制的电流波形，可以对房屋中存在的各种负载(包括新技术负载)进行分析。邻近房屋的输入电压和电流也被记录下来。基于在连接同一馈线的不同房屋进行的测量，提出了一个综合负荷模型。

Power Quality Monitoring and Analysis of the Domestic Grids - A Case Study

This paper presents the analysis of real time power quality data collected for 50 days at a domestic site in India. The data is collected using a dedicated PQ analyzer. The measurement and analysis are performed to identify the level of different grid disturbances and compared with relevant standards. Voltage unbalance and individual voltage harmonics are observed to be the major disturbances. In addition, the analysis of different kinds of loads, including new technology loads, present at the house is performed by recording the current waveforms drawn by these loads. The incoming supply voltage and current of the neighbouring houses are also recorded. An aggregate load model is presented based on the measurements performed at different houses connected to the same feeder.
