ClassA、S及B类测量方法对谐波测量的差异性研究
A comparative study on the measurement aggregation methods of class A, S and B to harmonic measurement
摘要
Abstract
Plenty of harmonics and inter-harmonics in the utility grid injected by fluctuating loads strongly have an im-pact on the safe and stable operation of power grid .According to GB/T 17626.30, there exist three kinds of measure-ment methods, namely class A、S and B, for each parameter measured, however, they are adopted by different instru-ments leading to the difference between measuring results in domestic power quality test instruments which become a long-standing issue .Based on the definition and algorithm of the three kinds of measurement methods of class A、S and B, this paper analyzes and compares the effects of the three kinds of measuring methods on harmonic analysis by their maximum value and 95%probability maximum value separately with the measured data of two typical fluctuating loads spot welder and EAF .Finally , from the perspective of practical engineering application , it proposes the applications and relevant conclusions for the three kinds of measurement methods respectively .关键词
