Abstract
The accurate extraction of voltage envelope is an important process for the flicker estimation. According to the latest IEC standard for design of flickermeter, the factor of fundamental frequency deviation is necessary to be taken into account. Therefore, a Prony-based technique is proposed in this paper. With the characteristic of high-frequency resolution in this method, the extraction of voltage envelope can be accurately performed for the time-varying power signals.
