(EN) TWO-SPOOL GAS TURBINE ARRANGEMENT
(FR) AGENCEMENT DE TURBINE À GAZ À DEUX CORPS
Abstract
(EN)
The invention concerns land-based gas turbine plants with a two-spool gas turbine arrangement for generating electrical power. The invention comprises two spools. The first spool (10) comprises a first shaft (11), a first compressor (C1) and a first turbine (T1). The second spool (12) comprises at least a second shaft (13) and a second turbine (T2). The shafts of the first and the second spools are independently rotatable of each other. The invention further comprises the first generator (G1) and the second generator (G2) having nominally substantially equal power ratings, and the rotating parts of the first generator (G1) and the second generator (G2) have nominally substantially equal rotational speed ratings, and at least 60 percent of a total output power supplied to said load (200) in a form of electrical and rotational power is generated by the two electrical generators (G1, G2).

L'invention concerne des centrales à turbine à gaz terrestres avec un agencement de turbine à gaz à deux corps pour générer de l'énergie électrique. L'invention comprend deux corps. Le premier corps (10) comprend un premier arbre (11), un premier compresseur (C1) et une première turbine (T1). Le second corps (12) comprend au moins un second arbre (13) et une seconde turbine (T2). Les arbres des premier et second corps peuvent tourner indépendamment l'un de l'autre. L'invention comprend en outre le premier générateur (G1) et le second générateur (G2) ayant des classes de puissance nominale sensiblement égales, et les parties rotatives du premier générateur (G1) et du second générateur (G2) ont des classes de vitesse de rotation nominale sensiblement égales, et au moins 60 % d'une puissance de sortie totale délivrée à ladite charge (200) sous la forme d'énergie électrique et rotative est générée par les deux générateurs électriques (G1, G2).
