基于某低压工业用户的电能质量分析

Power Quality Analysis Based on a Low-voltage Industrial User

随着现代社会的发展,加之电力设备和用电设备的敏感性不断增加,越来越多的低压用户开始关注电能质量问题。在实际应用中,电能质量检测主要是基于系统侧来考虑的。本文以广州市某低压工业用户的监测数据为核心,分析该用户的电压质量,包括电压偏移、电压谐波畸变率和三相电压不平衡度。然后将这些指标与国家标准对比,评价用电质量并对超标项提出整治措施。

With the development of modern society and the increasing sensitivity of power equipment and electrical equipment, more and more low-voltage users have begun to pay attention to power quality problems. In practical applications, power quality inspection is mainly based on the system side. This paper takes the monitoring data of a low-voltage industrial user in Guangzhou as the core, and analyzes the user＇s voltage quality, including voltage offset, voltage harmonic distortion rate and three-phase voltage unbalance degree. Then compare these indicators with national standards, evaluate the quality of electricity and put forward remediation measures for exceeding the standard.
