The discrete Fourier transform (DFT) is still a widely used tool for analyzing and measuring both stationary and transient signals in power system harmonics. However, the misapplications of the DFT can lead to incorrect results caused by some problems such as an aliasing effect, spectral leakage, and picketfence effect. A strategy of recursive(More)
With the increasing use of power electronic devices in the past decade, the produced harmonic pollution to the power supply is aggravating power supply quality. The monitoring of the health state of a power network is therefore becoming an essential issue. Although conventional techniques like discrete Fourier transform or fast Fourier transform are still(More)
The fast Fourier transform (FFT) and the power spectrum are still powerful tools for analyzing and measuring both stationary and transient signals in power systems. However, the misapplications of FFT can lead to incorrect results caused by some problems such as aliasing effect, spectral leakage, and picket-fence effect. Measurement errors can be(More)
