EUROESTUDIOS FERROVIARIOS S.L., e2f, trabaja en su departamento

de I+D en la creación y mejora del siguiente software de creación propia:

CECAT®

CÁLCULO ELÉCTRICO DE

DIMENSIONAMIENTO DE CATENARIAS EN

CORRIENTE CONTINUA Y CORRIENTE

ALTERNA.

El programa CECAT® , realiza el dimensionamiento eléctrico de una línea

ferroviaria en cuanto a análisis de mallas de trenes, consumos y potencias

necesarias en las subestaciones de alimentación a catenaria, contemplando

tanto la situación de funcionamiento normal como las situaciones degradadas

para el dimensionado de la línea.

Éste software ha sido desarrollado en colaboración con la Universidad

de Castilla- La Mancha, dentro del programa de investigación HI TO.

The studies performed by CECAT® are simulated for direct current ( 750V, 1500V, and 3000V) and for alternating current ( 1x25 kV and 2x25 kV ). The simulations are possible for all types of OCS: flexible, rigid and third rail.

Energy Efficiency: Regenerative braking and infrastructure efficiency.

Electrical Sizing Studies:

- Introduction input data: railway section, rolling stock, mesh flow and electrical characteristics.

- Results: topographics (profile and plan); kinematical (train speed in space and time, consumption...) and elctrics (shorts-circuits, visible tensions, pantrograph voltage, power in substations, feeder intensity…)

Conductor temperature study: It is determined the temperature reaching of the OCS conductors, and the results are verified with current regulations.

Electrical Sizing of railway systems in direct current ( 750V, 1500V, 3000V ) and alternating

current ( 1x25kV and 2x25kV ). This studies are done for all types of overhead contact

system; flexible, rigid and third rail.

*Analysis of the system operation with and without

taking into account the regenerative braking.

TEMPERATURE

Conductors Temperature Determination

Analysis focused on determine the temperature reached by the overhead conductors and its legislation verification

This analysis is more important in tunnels and areas with significant climatic variations

14

ENERGY EFFICIENCY

Energy Efficiency Studies: Analysis focused on the study of the energy in the railway installations according to:

Regenerative braking:

.Analysis of the energy distribution in the regenerative braking process and to study the implementation of energy recovery devices.

Infrastructure Efficiency:

To study the optimal cross section according to the optimal balance of losses.
