Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Traditional flicker detection method to accurately extract the amplitude envelope as the premise, the complexity of large amount of computation. This paper presents a new real-time detection of voltage flicker method, analysis method with recursive frequency carrier signal frequency; use of the adjacent three-point sampling data, the frequency carrier signal frequency, sampling frequency voltage flicker waveform obtained by the current envelope size. Of harmonic pollution by noise or flicker between the signals, the low-pass filtering results are not affected. Simulation results show that: The method to directly detect flicker signal, the process is simple, computational load and real time, tracking performance, with a certain anti-noise and inter-harmonic interference suppression capability, suitable for real-time detection of voltage flicker.
