Description

UNITE DE PRODUCTION D'ELECTRICITE ET/OU DE CHAUFFAGE La présente invention concerne le procédé d'une unité de stockage d'énergie et de production autonome d'électricité. Traditionnellement la production d'électricité est effectuée sans possibilité ou faible stockage d'énergie. Le concept de centrale solaire existe mais leur production dépend de l'ensoleillement.  The present invention relates to the method of a unit for storing energy and producing electricity autonomously. Traditionally electricity generation is carried out without possibility or low energy storage. The concept of solar power plant exists but their production depends on sunshine.
Le procédé selon l'invention permet de remédier à cet inconvénient. Le procédé innovant permet le stockage de l'énergie, la production de courant électrique ou de chauffage suivant un mode particulier de conception.  The method according to the invention overcomes this disadvantage. The innovative process allows the storage of energy, the production of electric current or heating according to a particular mode of design.
L'intérêt de notre procédé est d'assurer la disponibilité de l'électricité jour et nuit et ce, indépendamment des conditions d'ensoleillement.  The advantage of our process is to ensure the availability of electricity day and night and regardless of the conditions of sunshine.
La production d'électricité est assurée par un alternateur accouplé à une turbine à vitesse constante et produira en continu contrairement au photovoltaïque.  Electricity generation is provided by an alternator coupled to a turbine at constant speed and will produce continuously unlike photovoltaic.
La capacité de stockage thermique permet de produire de l'électricité ou du chauffage 24/24 heures pendant plusieurs jours de non ensoleillement. Les unités de production seront d'une puissance qui peuvent être couplées pour fournir plusieurs Mégawatts.  The thermal storage capacity allows to produce electricity or heating 24/24 hours for several days of non-sunshine. The production units will be of a power that can be coupled to provide several megawatts.
Cette unité de production électrique est à la base une centrale solaire thermique constituée d'un système solaire d'acquisition de chaleur (source chaude) qui alimente des turbines dans un cycle thermique de production électrique. Le stockage d'un fluide caloporteur à haute température > à 260°C permet d'assurer la disponibilité de la puissance nécessaire en période de rayonnement insuffisant ou non rayonnement.  This electrical production unit is basically a solar thermal power plant consisting of a solar heat acquisition system (hot source) which supplies turbines in a thermal cycle of electricity production. The storage of a high temperature heat transfer fluid> 260 ° C ensures the availability of the necessary power in periods of insufficient radiation or no radiation.
L'idée clef de ce procédé est de chauffer suffisamment un fluide, et permettre le stockage en quantité suffisante afin de faire fonctionner des turbines pendant les périodes de non ensoleillement et la nuit. Une telle intégration présente l'avantage de pouvoir égaliser les fluctuations en jouant sur la souplesse de l'unité. The key idea of this process is to sufficiently heat a fluid, and allow storage in sufficient quantity to operate turbines during periods of no sunshine and night. Such an integration has the advantage of being able to equalize fluctuations by varying the flexibility of the unit.

Ce principe améliore nettement le rendement énergétique d'un capteur.  In order to increase the efficiency of the tubes, ultra-retro reflective weather resistant mirrors are placed behind the tubes. The geometry of the mirror ensures that direct and diffuse sunlight falls on the absorber even in the presence of adverse angles of incidence. This principle significantly improves the energy efficiency of a sensor.

La vapeur expansée est condensée et pompée à nouveau vers la chaudière à vapeur pour ensuite accomplir un nouveau cycle.  The cycle starts with the heating of water (or oil) which turns into superheated steam at high pressure which then expands in a turbine.

Tant que la température nécessaire au stockage n'est pas atteinte, le fluide circule en boucle jusqu'à atteindre la température voulue. Lorsque la température est atteinte, Lorsque la température est atteinte, le fluide est orienté vers la capacité de stockage. The panels capture solar radiation and heat a heat transfer fluid at a temperature ≥ 260 ° C. Each panel unit is powered by a pump. As long as the temperature required for storage is not reached, the fluid circulates in a loop until the desired temperature is reached. When the temperature is reached, When the temperature is reached, the fluid is directed towards the storage capacity.
