Voltage and lamp flicker issues: should the IEEE adopt the IEC approach?

Abstract: This paper is intended to provide an overview of the IEC flicker measurement and assessment procedures. The IEC procedures are correlated with existing IEEE flicker standards to show the benefits of the IEC methodology. Application issues, such as customer impact assessment, are also discussed. Three case studies, two field tests, and one EMTP analysis are provided to show the correlation of IEC flickermeter output values with documented customer complaints. The case studies also provide areas where modificati… Show more

“…Voltage fluctuation detection can be defined as a single frequency amplitude modulation wave modulating the power frequency carrier [6], so, it is very important to extract amplitude modulated wave accurately. The extraction of amplitude modulation wave recommended by International Electrotechnical Commission (IEC) is square detection method [7], but the method includes the frequency multiplication components of amplitude modulation wave. Fast Fourier Transformation (FFT) algorithm is used to analyze the voltage flicker signal directly [8,9], but the method is suitable for analyzing the relatively stable signal [10].…”

“…Our protocol includes a collision detection mechanism, taking advantage of the sensing capability of LEDs, and compatible with our flicker elimination scheme. Flicker problems are well studied in fields like visual displays [10], lamps [11], and video games [12], but only partially addressed in current VLC designs. The 802.15.7 standard proposes to always keep the channel busy by transmitting messages with dummy data content.…”

“…As LFC, por exemplo, tem constante de tempo de arco da ordem de 5ms [25], conforme exemplo da Figura 3 (b). As LFC e as LLED têm dinâmica rápida e distinta da LI, sendo sensíveis às variações rápidas e à modulação de pico [4], [26]. As diferenças são evidentes já na forma de operação.…”
