“…Results presented in this section have been obtained on the synthetically generated voltage waveform with interharmonics to test the accuracy of the proposed approach and also the compatibility with the IEC flickermeter standard [1]. The study is carried out in accordance with the signal model given in (6). In that case, according to the standard, ∆V V = 0.1304 and it is expected that S max = 1, P st = 0.7146.…”

“…Another shortcoming of the IEC flickermeter is that it is adjusted only for the incandescent lamp [2]. However, studies show that modern lamps, such as compact fluorescents and LEDs, have different enlightenment response to fluctuating voltages [6][7][8][9][10], and the IEC flickermeter operates only for the incandescent lamp response. It has been emphasized that the standardized model for the incandescent lamp cannot measure the light flicker caused by other types of lamps [6].…”

It has been emphasized that the standardized model for the incandescent lamp cannot measure the light flicker caused by other types of lamps [6]. Tests on the amount of light flicker measured from different types of lamps show that even though the flicker severity measured from the input voltage exceeds the limits, the actual light flicker caused by the LEDs are much below the limits while compact fluorescent lamps (CFLs) exceed the limits a little, but not significantly [8].…”

A simplified Voltage Peak Detection (VPD)-based flickermeter based on spectral decomposition is proposed in this paper to detect flicker caused by high-frequency interharmonic components which effect the illumination of next-generation lamps, such as LEDs and compact fluorescent lamps. The proposed VPD-based flickermeter is specially designed to be robust to fundamental frequency deviations, which is a reality of all power systems. The proposed flickermeter is developed using a sinusoidal voltage model and it is analytically shown that flicker depends on the additive effect of the amplitudes of all the interharmonic components. Flicker results obtained by the proposed VPD-based flickermeter, IEC 61000-4-15 flickermeter, and another spectral analysis based IEC flickermeter are all compared with both synthetic voltage waveforms and field data collected from parts of the electricity transmission system with intermittent loads such as electric arc furnaces. It has been shown that only the proposed VPD-based flickermeter is sensitive to the high-frequency interharmonic components in the voltage spectrum and they are not detected by the other flickermeters. In the literature, there is no flickermeter that considers the flicker effect of the high-frequency interharmonic components and gives accurate results in cases of fundamental frequency deviations at the same time.

“…In the scientific literature there are three main approaches to quantify and compare the sensitivity of lamps to voltage fluctuations, those based on: i) Gain Factor curves [14,22,23,24,25]; ii) Pst curves for a given voltage fluctuation (e.g. sinusoidal amplitude modulation, SM, or rectangular amplitude modulation, RM) [26] and iii) Pst =1 curves (also known as Interharmonic/Flicker curves) [27,28]. Both approaches ii) and iii) require L-FMs [23,28] or alternative approaches [29] to be used.…”

According to current energy efficiency labels, the majority of LED lamps on the market are considered as highly efficient devices. This makes it difficult to distinguish between lamps with different operational characteristics and performance. This paper introduces a comprehensive experimental-based labelling methodology for comparing LED lamp performance with reference to two additional important characteristics: light flicker and power factor. The new labelling methodology reveals that there is high diversity between different LED lamps with different circuit topologies but also for a given topology with different design choices. General consumers and design engineers can benefit from the simple and clear information presented by the set of comparative labels when comparing LED lamp performance.
