Abstract

Le cursus universitaire des étudiants de l'EPFL comprend, outre des cours magistraux, des travaux dirigés et des ravaux pratiques, la réalisation de projets de semestre et de diplômes. Les étudiants ont ainsi l'occasion, au travers de ces projets, soit de parfaire leurs connaisances soit d'aquérir en auto-apprentissage de nouvelles compétences.De tels projets représentent ainsi des moments forts dans la formation des ingénieurs, d'autant qu'ils sont effectués en laboratoires de recherhce, et que les thémes proposés sortent du charactére purement académique pour embrasser une problématique de recherche ou de développement propre á susciter la motivation des étudiants. Le propos de cette contribution est de présnter une maquette de train, alimenté par supercondensateurs. Il s'agit en premier lieu d'un thème de recherche du LEI. Mais la réalisation de cette maquette a été confiée à des étudiants, qui se sont succédés et qui ont dû mettre en ceuvre de compétences pluridisciplinaires pour parvenir au résultat présenté ici.

Maximum power point tracking

Maximum power point tracking (MPPT), or sometimes just power point tracking (PPT), is a technique used with variable power sources to maximize energy extraction as conditions vary. The technique is most commonly used with photovoltaic (PV) solar systems, but can also be used with wind turbines, optical power transmission and thermophotovoltaics. PV solar systems have varying relationships to inverter systems, external grids, battery banks, and other electrical loads.

Solar-cell efficiency

Solar-cell efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system. For example, a solar panel with 20% efficiency and an area of 1 m2 will produce 200 kWh/yr at Standard Test Conditions if exposed to the Standard Test Condition solar irradiance value of 1000 W/m2 for 2.

Energy storage

Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms.
