“…3. Such a device is responsible for generating an output signal with sampling rate 2 5 times less than the rate of the input signal. The Fast Fourier transform (FFT) applied to the subsampling signal will estimate the magnitude, however the frequencies presented by the FFT need to be corrected.…”

“…The high frequency (supraharmonic) emission in the range from 2 kHz to 150 kHz has recently gained significant attention [1]- [3]. This topic has been discussed in recent years, but the amount of systematic knowledge in the field is limited, even instruments applied in power quality measurement do not reach this frequency range [4]- [5]. Considering that the vast majority of actual monitors complies with IEC 61000-4-30 standard Edition 2 that does not address supraharmonics and that Edition 3 points to this frequency range it is necessary to update the current PQ monitors.…”

“…Diferentemente dos diversos PSCs disponíveis, ele não possui uma arquitetura fixa. O SAPHO já foi utilizado em diversos sistemas consolidados, como nos trabalhos [11], [12] e [13], por meio dos quais é possível obter detalhes mais aprofundados a respeito da estrutura e funcionamento do mesmo.…”

“…O desequilíbrio de cargas e um inadequado balanço geração/demanda podem causar desvios na frequência fundamental do sistema (Phadke e Thorp, 2017). Além disso, no cenário das REI, novos distúrbios elétricos ainda desconhecidos podem ocorrer (Kapisch et al, 2016).…”

“…Muitas das técnicas de detecção de novidade dependem de parâmetros definidos pelo usuário, fazendo com que alguns eventos na forma de onda sejam ignoradas pelo detector, resultando em perda de eventos. A fim de melhorar o desempenho do detector, de forma a aumentar a capacidade de detecção e reduzir os falsos positivos, técnicas adaptativas baseadas em wavelets, variação de energia e morfologia do sinal têm sido pro-postas (Bastos e Santoso, 2019), (Kapisch et al, 2016), (Han e Zhou, 2016), (Silva et al, 2017).…”
