Title
(EN) CONTROL SCHEMES FOR THERMAL MANAGEMENT OF POWER PRODUCTION SYSTEMS AND METHODS
(FR) SCHÉMAS DE COMMANDE POUR LA GESTION THERMIQUE DE SYSTÈMES ET PROCÉDÉS DE PRODUCTION D'ÉNERGIE
Abstract
(EN)
The present invention relates to systems and methods for controlling a power production plant and optionally providing a one or more product streams for an end use thereof. Control of a power production plant specifically can include executing one or more functions effective for adjusting a heat profile of a heat exchange unit (HEU) operating with a plurality of streams passing therethrough. This can include implementing a control function that alters a flow of one or more of the plurality of streams by adding flow to or withdrawing flow one or more of the plurality of streams at an intermediate temperature range within the HEU at a point that is positioned between a first end and a second end of the HEU.

La présente invention concerne des systèmes et des procédés permettant de commander une centrale de production d'énergie et éventuellement de fournir un ou plusieurs courant de produit en vue d'une utilisation finale de ceux-ci. La commande d'une centrale de production d'énergie peut plus particulièrement comprendre l'exécution d'une ou de plusieurs fonctions efficaces pour ajuster un profil de chaleur d'une unité d'échange de chaleur (HEU) fonctionnant avec une pluralité de courants passant à travers celle-ci. Ceci peut consister à mettre en œuvre une fonction de commande qui modifie un flux d'un ou plusieurs courant de la pluralité de courants en ajoutant un flux ou en retirant un flux à un ou plusieurs courant de la pluralité de courants à une plage de température intermédiaire à l'intérieur de l'HEU en un point qui est situé entre une première extrémité et une seconde extrémité de l'HEU.
