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.
First voltage flicker through the trigonometric decomposition into harmonic signals between the design of a time-frequency filter, with the Hilbert transform in the frequency of negative axle, through the high-precision time-domain convolution method to detect the signal of the second harmonic Between the harmonic wave frequency, amplitude and phase, the equation obtained by the signal into the frequency of voltage flicker signal, amplitude and phase. Harmonic pollution being flicker between the signals, the test results are not affected. Simulation results show that: the time domain convolution method to directly detect flicker signal, estimated signal parameters, is simple, operation is small, and there is a certain anti-noise ability, to effectively improve the low SNR flicker detection accuracy Suitable for real-time detection of voltage flicker.
