“…Several works have treated the prediction of the amount of current harmonic that the ESLs inject into the power grid [60][61][62][63][64][65][66][67][68][69][70][71][72]. In [60] has been investigated the effect of the employing of many energy-saving lamps on the power grid in New Zeeland.…”

“…The main objective of [61] has been the prediction of the maximum number of CFLs that can be used without overcome a threshold value of THD imposed by the users. In [62] the results of a research performed on energy-efficient electronic ballasts for T8 fluorescent lamps have been presented. Unlike the previous cases, the CFL behaviour in a distribution system a fixed harmonic injection method has been adopted, where the single CFL has been modelled by means of an ideal current source.…”

“…Moreover, the tensor analysis with phase dependency is used with the aims to take into account the harmonic interaction of the mains voltage in the CFL harmonic currents. The analysis of the power factor and harmonic emission of CFLs have highlighted that the current drawn of the lamps are influenced by the main voltage variation [60][61][62][63].…”

Energy-saving lamps are equipped with converters enabling high energy efficiency at the cost of injecting very distorted currents on the mains. The problem is more complex in the emerging smart-lighting scenario where these lamps are also used to perform additional tasks. Harmonics mitigation at the lamp level is expensive; consequently, an optimal lighting system design aiming at reducing both costs and current distortion of the whole lighting system is necessary. A tool able to emulate the current drawn from the lamps is necessary for optimal design. Such a tool has also to consider the fluctuations of the voltage on the mains that usually occur throughout the day. In this perspective, a parametric PSpice circuit is proposed and the netlist is reported in this work. Moreover, the simple procedure to be adopted for computing the parameters is also described. The validation has confirmed the ability of the proposed circuit in emulating the current drawn from various CFLs and LED lamps under different supplying voltage.

“…Only a set of URs (power supplies of PCs) and a set of FLs (magnetically ballasted lighting devices) connected at the same voltage level are considered, meaning that only harmonic cancellation due to the third factor is analyzed. Such an in-depth study is essential because both types of NLLs are very present in commercial and residential sectors: PCs are the most common small-power NLLs in low-voltage installations [2], and FLs are among the most used and efficient lighting devices because of their low cost and simple design [1,2,32]. The study is based on the univocal characterization of these devices through their invariants.…”

An Appropriate Index to Assess the Global Cancellation Level of the Harmonic Currents Consumed by a Set of Single-Phase Uncontrolled Rectifiers and a Set of Fluorescent Lamps

An in-depth study of harmonic current reduction in European commercial buildings due to the harmonic cancellation effect when a set of single-phase uncontrolled rectifiers and a set of fluorescent lamps are connected at the same voltage level is essential, since both types of non-linear loads are very present in commercial and residential sectors. This paper provides an appropriate index to assess the global cancellation level of the harmonic currents for this study. The equivalent circuit per phase of the typical three-phase power system of European commercial installations is presented and simplified for the cancellation analysis of the harmonic currents consumed by a set of multiple identical single-phase uncontrolled rectifiers and a set of multiple identical fluorescent lamps connected at the same voltage level. The suitability and usefulness of the proposed index are shown by applying it to that analysis, which leads to some results of practical interest. This index can be generalized to any number of sets of multiple identical non-linear loads and can be applied in graphical and optimization studies that will allow a greater benefit from the harmonic cancellation effect to be obtained given the global nature of the index.

“…Each type of lamp has different properties and must be chosen according to its use. Fluorescent and compact fluorescent lamps are low-pressure mercury gas lamps in the 5-150 W range used in residential, commercial and industrial installations [4][5][6][7][8][9][10][11][12]. The other types of DLs (high-pressure mercury and sodium gas lamps and metal halide gas lamps) are employed in street or public lighting with a power consumption range of approximately 100-500 W [13][14].…”
