“…Reference must also be made to papers addressing the control of viability in electrical terms, and in terms of an automatic search for the best possible power supply system. There are a number of approaches to this problem, mainly found in [14] [15] [16]. The first two attempts to model a low-level 2x25 system, for the purposes of conducting an analytical survey of the characteristics of the model applied.…”

With the rapid development of the construction of high-speed railway in china, higher levels of power quality and reliability of traction power supply systems are required. The combination of bilateral power supply technology with AT traction power supply technology can better meet the needs of development of high-speed railways, which will require new protection approaches to be proposed. Thus, corresponding protection schemes will be of great significance for the application and promotion of bilateral power supply technology.

“…In mono-voltage systems, the feeding conductors are set directly to the specified voltage level (see Figure 2). In bivoltage systems, a higher voltage is set between feeding conductors [6,7]. This voltage is reduced by using autotransformers distributed along the catenary (see Figure 3).…”

This paper presents an optimization model based on genetic algorithms for designing traction power supply systems. The proposed model is suitable both for planning new lines and for expanding the old ones, resulting in a more efficient operation as well as in lower investment costs. Minimization of fixed installation represents the optimization criterion for searching innovative designs that fulfil certain technical constraints: maximum voltage drops and maximum power consumption in the substations. The variables involved in the optimization problem are: number, type and location of railway overhead lines; and number, size and location of traction substations. Finally, the evaluation of possible designs involves simplified electrical modelling of the studied railway stretch. Thus, electrical simulations and calculations have been also adapted for their implementation in the genetic algorithm. A section of the Madrid-Barcelona high-speed line has been considered as a study case in order to analyze the performance of the proposed model. Results reveal the suitability of the new designs obtained with the presented model and its goodness and robustness.
