“…The data used for this paper is available in PANDA (equiPment hArmoNic DAtabase), a global web-based platform for exchanging harmonic emission measurements from all types of household equipment (single-phase) between different laboratories around the world (http://www.panda.et.tu-dresden.de) [12]. For this analysis, only data measured at IEEH (Institute of Electrical Power Systems and High Voltage Engineering of the Technische Universität Dresden) has been considered, in order to guarantee that all the lamps were measured under the same conditions.…”

Measurements have shown that the harmonic currents emitted by lamps with electronic ballast depend on the circuit topology and the existing supply voltage distortion. This paper quantifies the impact of supply voltage distortion on the harmonic and supraharmonic current emission of individual Light Emitting Diode (LED) lamps and compact fluorescent lamps (CFL). It also characterizes several Power Quality (PQ) parameters when those lamps are connected to pure sinusoidal waveform.

“…Only lighting loads are taken into account, which are represented for simplicity, independently of their location in the network, by complex current sources including the fundamental and the odd harmonics up to order 15 [20]. All harmonic current sources are modeled using measurements of commercially available lamps provided by the PANDA database [21]. To study the difference between theoretical sinusoidal supply voltage (230 V Root Mean Square (RMS)) and the more realistic flat-top distorted supply voltage (224 V RMS and Total Harmonic Distortion of 3%), two-parameter sets for the complex current sources are applied for each lamp.…”

“…As it was intended to provide a first estimate of the impact, all lamps were represented by harmonic current sources [20] and, consequently, the series impedance of the lines and the supply transformer were omitted. The current harmonic spectra were obtained from a large sample of measurements of commercially available lamps provided by PANDA (equiPment hArmoNic Database, Dresden, Germany) [21]. The impact of a flat-top supply voltage distortion [22,23], which is common for public LV networks, was compared with the behavior under perfect sinusoidal condition, which represents the reference for testing compliance with emission limits.…”

Impact of Nonlinear Lighting Loads on the Neutral Conductor Current of Low Voltage Residential Grids

In the last decade, mainly due to political incentives towards energy efficiency, the share of lamps with power electronic interfaces, like Compact Fluorescent Lamps (CFL) and Light Emitting Diode (LED) lamps, has significantly increased in the residential sector. Their massive use might have a substantial impact on harmonic currents and, consequently, on the current flowing in the neutral conductor. This paper analyzes the impact of modern energy-efficient lighting technologies on the neutral conductor current by using a synthetic Low Voltage residential grid. Different load scenarios reflecting the transition from incandescent lamps, via CFL, to LED lamps are compared concerning the neutral conductor current at different points in the network. The inherent randomness related to the use of lighting devices by each residential customer is considered employing a Monte Carlo simulation. Obtained results show that the use of CFL has a greater impact on the neutral conductor current of Low Voltage (LV) residential grids and that, with increasing use of LED lamps, a decreasing impact can be expected in the future.

“…Para avaliar o desempenho do método para sinais reais, uma forma de onda contendo distorções supraharmônicas originada por uma lâmpada de LED foi testada. Este sinal foi obtido através do banco de dados da Web PANDA (EquiPment hArmoNic Database) (Blanco et al, 2012). Este banco de dados da Web foi recentemente desenvolvido, seus autores objetivam promover uma plataforma para a troca de medições harmônicas de equipamentos eletrônicos entre laboratórios de todo o mundo.…”

Smart grids encourage the use of new technologies such as electric vehicles, smart metering, as well as the use of renewable energy sources. Such new technologies are the main sources of supraharmonic distortions. However, there are few analytical techniques and equipment capable of performing measurements in the supraharmonic range. This work applies techniques of multirate signal processing for the purpose of supraharmonic analysis. The proposed methodology employs a polyphase uniform DFT filter bank. The polyphase representation applied to the decimation filter bank allows simplification of the system and makes it computationally efficient. The proposed method shows a good perspective of application in the measurement of supraharmonic with precision. Resumo: As Smart Grids incentivam o uso de novas tecnologias, tais como veículos elétricos, medidores inteligentes, assim como o uso de fontes de energia renováveis. Tais novas tecnologias são as principais fontes de distorções supraharmônicas. No entanto, existem poucas técnicas de análise e equipamentos capazes de realizar medições na faixa supraharmônica. Este trabalho aplica técnicas de processamento digital de sinais multitaxa para fins de análise de distorções supraharmônicas. O metodologia proposta emprega um banco de filtros DFT uniforme polifásico. A representação polifásica aplicada no banco de filtros de decimação permite a simplificação do sistema e o torna computacionalmente eficiente. O método proposto mostra uma boa perspectiva de aplicação na medição de supraharmônicas com precisão.
