“…In [7], [16], [17], the authors show the problems caused by harmonic distortion, mainly due to the increases of nonlinear loads on the electrical system. The concern involves some questions, such as how to calculate the electrical energy billing on nonsinusoidal system and if high harmonic currents can cause significant errors on the meters.…”

“…Moreover, related to electrical energy billing, the discussion is more interesting. In [16], [29], the authors present the rules and discussions about the electrical energy billing in Brazil and some other countries, respectively. Therefore, it is possible to conclude that if a consumer unit has a load profile similar to one of the studied scenarios, it can pay or not for surplus reactive power.…”

This paper presents an investigation of the harmonic interaction among lighting devices and its effects on the electrical quantities, billing and power quality. In this study, two types of bulbs, a programmable AC power source, a power quality analyzer, and an oscilloscope were used. Aiming to analyze the impact of the massive introduction of the LED bulbs in the electrical energy system, simulations were realized and several scenarios were considered. The results show that the electrical quantities, such as power factor (PF), displacement power factor (DPF) and total harmonic current distortion (THDi) are function of the harmonic interaction between each harmonic order of each load. Therefore, the characteristics of each load will influence directly in the results. Another contribution of this paper is to show the necessity of reviewing the electrical energy billing rules.

“…De fato, o custo da energia elétrica para consumidores de média tensão é baseado não somente na energia/potência ativa, mas também na reativa [2] e no fator de potência. Todavia, para condições de sinais distorcidos de tensão e/ou corrente elétrica, não existe um consenso na literatura sobre a metodologia adequada para o cálculo da energia/potência reativa [3]. Nessa perspectiva, várias teorias de potência foram desenvolvidas com o intuito de apresentar um melhor significado físico a respeito de cada parcela de potência.…”

A medição da potência elétrica em condições não senoidais é tema de diversos estudos na comunidade científica, todavia, ainda não existe um consenso sobre a metodologia mais adequada para cálculo da potência, sobretudo, da parcela reativa. Somado a isso, deve-se ainda reconhecer que os medidores comerciais utilizam diferentes métodos de medição da potência elétrica. Esses fatores contribuem para uma divergência na medição da potência reativa e do fator de potência em circuitos com chaveamento eletrônico. Dessa forma, esse trabalho visa avaliar duas metodologias para o cálculo da potência elétrica, uma primeira utilizada em medidores de faturamento de energia na qual é denominada de método do triângulo de potências, e uma segunda baseada na publicação IEEE Std. 1459-2010. Para isso, são simulados três distintos circuitos elétricos com elevado conteúdo harmônico. Ao final do trabalho, com os resultados apresentados, poderá se concluir que, a depender da metodologia utilizada, a distorção de tensão e/ou corrente pode influenciar significativamente na potência reativa e no fator de potência calculados.

“…This fact becomes relevant, for example, in the Brazilian billing system, since the billing of the surplus of reactive is based on the characteristic of the consumer unit before the measurement system and according to the established schedules. In summary, it directly affects electric energy billing for Brazilian medium and large consumers [55].…”

This paper evaluates the impact of voltage distortion on the electrical quantities measured by revenue meters and the influences on the electrical energy billing. This is done through an experimental setup, which combines the following variables for the first time in an experiment: different total harmonic voltage distortion (THDv) levels; among these levels, different harmonic profiles; and different loads. A programmable alternating current (AC) power source was used in the laboratory to apply voltage signals in three electronic loads: a compact fluorescent lamp (CFL) and two light emitting diode (LED) lighting devices for which voltage signals with THDv 4.9%, 18.8% and 24.5% have been applied. All applied signals contain one or more harmonic order more commonly found in the low voltage grid (3rd, 5th and 7th). For these analyses, a power quality analyzer and a revenue meter were used. The results show that significant and diverse effects on the electrical quantities of individual loads will occur with different THDv levels and harmonic profiles. Comparing with a reference case (sinusoidal condition), when a distorted signal was applied, for the same THDv level, some parameters remained numerically the same, some have improved and some have become worse. This study shows that the effects of combination of the variables such as different THDv level with different harmonic profiles on electrical quantities of loads are not as clear as the effects of considering only one variable. The results of this paper shed light on such effects.
