Embodiment Construction

[0030] exist Figures 1 to 7 A first example of this method is shown in .

[0031] Particularly, figure 1 and 2 Power plant 1 before improvement is shown.

[0032] As shown in the figure and as previously described, the generator 4 comprises an original active part 7 which produces electricity and an original non-active part which cooperates with the original active part 7 .

[0033] The original inactive part includes, for example, the gearbox 8, the exciter 9, and the cooler 10; in other examples, the original inactive part can include a compressor, one or more fans, and / or a bushing system. Of course, in further embodiments of the power plant 1 different inactive parts and / or their different combinations and / or positions are also feasible.

[0034] In this example, reference is made in particular to the exciter 9, which can be an exciter with slip rings. As shown in the figure, the original active part 7 and the original inactive part which is the exciter 9 are adjacen...

Abstract

The method for retrofitting a power plant (1) comprises the steps of: removing the original active part (7), removing the original non-active part (8, 9, 10, 24, 25, 28), providing a new active part (15) that is larger than the original active part (7), and at least partly extends over a zone that was before occupied by the original active part (7), and at least partly extends over a zone that was before occupied by the original non-active part (8, 9, 10, 24, 25, 28), and is housed within the foundation (6).

Description

technical field [0001] The invention relates to a method for improving a power plant. Background technique [0002] The following reference figure 1 . A power plant usually has a prime mover or engine that drives a generator; in particular, figure 1 An example is shown of a power plant 1 with a first engine 2 , which is a gas turbine, and a second engine 3 , which is a steam turbine; both gas turbine 2 and steam turbine 3 are connected on opposite sides of a generator 4 . [0003] The gas turbine 2 and the steam turbine 3 are located on a foundation 5 and the generator 4 is housed in a frame 6 . [0004] The generator 4 includes an active part and a non-active part. [0005] The active part generates electricity and typically comprises a stator with stator windings and a rotor with field windings; in the following, the active part is indicated with reference numeral 7 . [0006] The non-active part includes ancillary equipment required for the correct operation of the ...
