Title
(EN) HYBRID COMBUSTION TURBINE POWER GENERATION SYSTEM
(FR) SYSTÈME DE PRODUCTION D'ÉNERGIE À TURBINE À COMBUSTION HYBRIDE
Abstract
(EN)
A hybrid combustion turbine power plant (30) in which a conventional gas turbine (11, 12, 14) is integrated, via a fluid connection (32), with an adiabatic compressed air energy storage system (ACAES) comprising a direct TES (thermal energy store) (40) and, downstream thereof, a supplementary compressor (52) and pressure reducing device (50) disposed in alternative pathways between the direct TES and compressed air store (60). The ACAES discharges air into the gas turbine via the fluid connection at a desired mass flow rate through the pressure reducing device, but charges with air via the supplementary compressor at a lower mass flow rate over a longer period of time, trickle charging allowing the use of a low power supplementary compressor. The use of a direct TES (40) efficiently returns the heat of compression. Alternatively, variable mass flow, reversible power machinery (70) and a second TES (72) may be provided downstream of the direct TES (40), allowing overall power modulation and switching between compression and expansion to charge or discharge the ACAES, respectively, with even low power reversible power machinery achieving significant power modulation.

La présente invention concerne une centrale électrique à turbine à combustion hybride (30) dans laquelle une turbine à gaz classique (11, 12, 14) est associée, par l'intermédiaire d'un raccordement fluidique (32), avec un système de stockage d'énergie à air comprimé adiabatique (ACAES) comprenant un TES (stockage d'énergie thermique) direct (40) et, en aval de celui-ci, un compresseur supplémentaire (52) et un dispositif de réduction de pression (50) disposés dans des voies alternatives entre le TES direct et l'accumulateur d'air comprimé (60). L'ACAES évacue l'air dans la turbine à gaz par l'intermédiaire du raccordement fluidique à un débit massique souhaité à travers le dispositif de réduction de pression, mais se charge en air par l'intermédiaire du compresseur supplémentaire à un débit massique inférieur sur une période de temps plus longue, une charge de maintien permettant l'utilisation d'un compresseur supplémentaire à faible puissance. L'utilisation d'un TES direct (40) renvoie de manière efficace la chaleur de compression. En variante, un écoulement massique variable, des machines de puissance réversibles (70) et un second TES (72) peuvent être prévus en aval du TES direct (40), ce qui permet la modulation globale d'énergie et la commutation entre compression et expansion pour charger ou évacuer l'ACAES, respectivement, même lorsque des machines de puissance réversibles à faible puissance atteignent une modulation de puissance significative.
