Enhancement of the equivalent 10-Hz voltage flicker measurement

This paper aims to analyze and improve the existing equivalent 10-Hz voltage flicker measurement. The ΔV10 method has been employed to evaluate voltage flicker for more than two decades in several Asian countries and not been updated since 1978. The analysis results in this paper reveal the deficiencies in the reliability of the typical ΔV10 method implemented in frequency domain. Therefore, a time-domain-based and statistical-analysis ΔV10 method is proposed which can mitigate the drawback of the typical method. Various tests against the proposed method are made and the results prove its feasibility.
