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.
