“…The railway system model was implemented in a rail simulator based on the 'quasi static' backwards looking method, due to its short simulation times for estimating energy consumption of vehicles following an imposed speed cycle [46]. The rail simulator is a multi-stage program, implemented in Visual Basic and Fortran language and operating in MS-DOS and the Microsoft Excel workspace [59][60][61], including:…”

“…That is, within 10 s, the rotor (artificially) remains stationary. From this experiment, we find at which current, according to (4,5), the moments are equalized and we obtain the start time of the starter rotor movement. For greater obviousness, the time axis is given by an uneven scale since, starting from 1.5 to 10 s, the process proceeds relatively smoothly.…”

“…That is likely due to the complexity of selecting the parameters for existing supercapacitors, starters, and rechargeable batteries. The results of studying the system of guaranteed power supply with various power drives are reported in [4]. In particular, the authors investigated an option to start a diesel generator only from the supercapacitor.…”

Supercapacitors are commonly used for a guaranteed launch of diesel generators. However, the processes caused by the starting current until the starter shaft rotates are disregarded. The duration of this moment is short but its effect on the rechargeable battery, taking into consideration its service life, is significant. The shape of this pulse, its duration significantly depend on the ratio of system parameters: supercapacitor (rechargeable battery) – starter – diesel generator. A system of differential equations has been proposed to describe the compatible electromagnetic and electromechanical processes that occur when the starter of the diesel generator is powered from the supercapacitor. A charge is used as a variable quantity. The transitional processes occurring in the stationary starter rotor and the subsequent processes caused by the growth of the electromagnetic starter moment have been taken into consideration. This paper reports establishing those patterns that are related to the beginning of the starter movement, its entering the mode at the falling voltage of the supercapacitor, the exchange of electrical and magnetic energy accumulated in the inductive elements of the starter. Using the charge as a variable quantity has made it possible to combine the final values of the preceding process (stationary rotor) with the initial ones of the next one (output to starting speed). Thus, a mathematical notation has been derived that considers most of the parameters of the charge circle of the supercapacitor. The possibility of using an inflated voltage of the supercapacitor to increase the accumulated energy has been clarified. The processes have been theoretically substantiated, which makes it possible to use a small internal resistance of the starter circuit, the presence of inductive components, an abnormal capacity of the supercapacitor to form the desired shape of the electromagnetic moment. That would make it possible to take into consideration the specific requirements of various systems of guaranteed power supply.

“…The train performance, computed in the Microsoft Excel environment, requires the main characteristics of the route as input data, namely the plano-altimetric characteristics of the line (slopes), the curvature radius of the curves, speed limits and tunnels. Moreover, it requires electromechanical information of the rolling stock such as: weight, aerodynamic resistance, traction and braking force [46,59]. Given these inputs, and with a calculation step in meters, it is possible to obtain several outputs such as:…”

The paper presents a preliminary technical-economic comparison between a 3 kV DC railway and the use of trains with on-board storage systems. Numerical simulations have been carried out on a real railway line, which presents an electrified section at 3 kV DC and a non-electrified section, currently covered by diesel-powered trains. Different types of ESS have been analyzed, implementing the models in Matlab/Simulink environment. A preparatory economic investigation has been carried out.
