Patent number: 11208949Abstract: The present invention is a system, method and computer program for operating a land-or marine-based multi-spool gas turbine system for generating electrical power to supply a load, wherein the system comprises a multi-spool gas turbine engine, and the method comprises controlling the rotational speeds of the at least two generators independently of each other so as to directly control the rotational speeds of the shafts of the spools, the at last two generators being operable to generate electrical current to supply the load, and regulating the amount of heat generated the first heat generating equipment. A computer program to perform the method is also disclosed.Type: GrantFiled: August 19, 2016Date of Patent: December 28, 2021Assignee: AURELIA TURBINES OYInventors: Matti Malkamäki, Ahti Jaatinen-Värri, Jari Backman, Juha Honkatukia

Patent number: 10626746Abstract: 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 comprises a first shaft, a first compressor and a first turbine. The second spool comprises at least a second shaft and a second turbine. The shafts of the first and the second spools are independently rotatable of each other. The invention further comprises the first generator and the second generator having nominally substantially equal power ratings, and the rotating parts of the first generator and the second generator have nominally substantially equal rotational speed ratings, and at least 60 percent of a total output power supplied to said load in a form of electrical and rotational power is generated by the two electrical generators.Type: GrantFiled: March 23, 2016Date of Patent: April 21, 2020Assignee: AURELIA TURBINES OYInventors: Matti Malkamäki, Jari Backman, Juha Honkatukia, Ahti Jaatinen-Värri

Patent number: 10458269Abstract: The invention concerns land-based gas turbine plants with a multi-spool gas turbine arrangement for generating electrical power to supply a load (200). The invention comprises at least three spools (10a-10c). Each of the at least three spools (10a-10c) comprises a shaft (11a-11c), a compressor (C1-C3) and a turbine (T1-T3). Each one of the shafts (11a-11c) of the at least three spools (10a-10c) are independently rotatable with respect to each other. The invention further comprises electrical generators (G1-G3) mounted on each of the shafts (11a-11c) of the at least three spools (10a-10c), the output power of the generators being independently controllable 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 at least three generators (G1-G3) in the form of electrical energy.Type: GrantFiled: March 23, 2016Date of Patent: October 29, 2019Assignee: AURELIA TURBINES OYInventors: Matti Malkamäki, Jari Backman, Juha Honkatukia, Ahti Jaatinen-Värri
