摘要

测量/监测电能质量(PQ)仪器的准确度存在固有差异，这促使巴西传输独立系统运营商(ONS-巴西ISO) ONS进行了全面的现场活动和实验室测试。这些测试已允许对大量市售仪器的准确性和测量方法进行评估。本文给出了不同仪器性能的实验室测试结果。所有仪器同时输入相同的电压信号。实验室测试包括最常见的电能质量指标，如:稳态电压、频率变化、不平衡电压、电压波动和短时电压变化(凹陷)。

Assessing the accuracy of power quality instrumentation

The inherent differences in the accuracy of measuring/monitoring power quality (PQ) instrumentation has led the Brazilian transmission independent system operator (ONS-Brazilian ISO) ONS to conduct a comprehensive field campaign and laboratory tests. These tests have allowed for evaluation of the accuracy and measurement methodology for a large number of commercially available instruments. This paper presents the laboratory test results for the performance of the different instruments. All of the instruments were simultaneously fed the same voltage signal. Lab tests were conducted which included most common power quality indices such as: steady state voltage, frequency variation, unbalance voltage, voltage fluctuation and short duration voltage variation (sag).
