“…Article [5] considers the structure of the imbalance of electric power losses during a train operation, which reaches up to 17%. Experimental research showed that the annual loss of electricity in TPSs is 13.3%, including losses in step-down transformers of 0.7-1.5% of the nominal volume of electricity received from the external power system and losses in traction transformers of 0.81-1.51% of the energy released for train traction.…”

“…As follows from the publications analysed above [1][2][3][4][5][6][7][8] and also many other publications, which are not mentioned in the article, the assessment of power losses in the TPS is carried out either by calculation (analytical or modelling) or experimentally by power meters installed on TSs and ERSs. In the former case, the calculated input data are the electrical parameters and currents in the catenary system, and in the latter case, the currents and voltages of the corresponding electrical circuits of the TS and ERS.…”

“…At the same time, the existing approaches and methods for electricity loss estimation in grids are the weakest link in the overall energy balance calculation circuit. In our opinion, this is due to the fact that traditional methods for analysis and reduction in energy losses in electric traction networks are based on the "circuit" approach, that is, on the theory and electrical appliances of electrical circuits, which follows from the analysis of publications [1][2][3][4][5][6][7][8]. This article continues and expands on the researches outlined in [9,10].…”

This article presents a new method for the estimation of active power losses based on a “field” approach, i.e., on the theory of the electromagnetic field and the theory of propagation of electromagnetic waves in a dielectric medium. Electromagnetic waves are assumed to transmit energy from the traction substation to electric rolling stock through the airspace of the inter-substation zone (i.e., not through the wires of the traction network) and meet electrically conductive surfaces on their way. The waves are partially reflected from the surfaces and partially penetrate them, thus creating thermal losses, the determination of which is the main task of this article. The analytical expressions for specific losses of active power are obtained by solving the system of Maxwell’s equations. Calculations of specific power losses in the catenary, rails, roofs, and bottoms of carriages and electric locomotives are performed. Power losses in carriages and electric locomotives are found to be at least 7%. A comparative assessment of the magnitude of total power losses of different types obtained by the “field” and “circuit” approaches is provided, which has established that “conditional” losses correspond to losses in rails, train carriages, and electric locomotives.

“…Energy consumption and fair billing aspects have become increasingly relevant, considering the efforts to improve energy efficiency, especially for modern smart transportation systems [19] [20] and the introduction of a complex normative for on-board energy metering [13]. Metering is achieved by measuring the electrical quantities at the interface between the load and the network: the measured voltage and current at the sliding contact supported by the train pantograph, vp and ip, can be used for both PQ [21]- [25] and energy metering [14]- [18] purposes.…”

<p class="Abstract">In electrified railways, harmonic active power terms can be significant in the order of the uncertainty required by the EN 50463-2 standard for power and energy measurements in railways. Nonactive power terms (encompassing reactive and distortion harmonic terms) are much more significant than the sole fundamental reactive power. This work considers the implementation of the EN 50463-2 energy measurement function, including the criteria for the significance of the measured and calculated terms, and it carries out a Monte Carlo analysis to assess the impact of harmonic power terms on the measured energy and its uncertainty.</p>
