Embodiment Construction

[0039] image 3 A very simplified circuit diagram of a power plant installation with a gas turbine and an electronic decoupling device is shown, as it is suitable for carrying out the method according to the invention. The power plant installation 10 comprises a gas turbine 12 with a compressor 13 and a sequential combustion arrangement in which a first combustion chamber 15 is supplied with a first fuel via a first fuel supply line 17 to generate hot gas, which is expanded in a first turbine 14a and then introduced into a second combustion chamber 15', where the hot gas is induced by a second fuel through a second fuel input line 17' to generate hot gas superheated in the middle, and then the hot gas is expanded in the second turbine 14b. However, instead of a sequential combustion configuration which is particularly advantageous in terms of efficiency, a single-stage fuel configuration can also be provided. The remaining parts of the device correspond to figure 1 Or the ...

Abstract

The invention relates to a method for operating a power plant (10) comprising a turbine train (11) composed of a gas turbine (12) and a generator (18), directly driven by the gas turbine (12) and generating alternating current of an operating frequency, the output of said generator being connected to a network (21) of a predetermined network frequency. An electronic decoupling device (27) is interposed between the generator (18) and the network (21) and decouples the operating frequency from the network frequency. In order to extend the service life of the plant and to reduce emissions, the mechanical or aerodynamic rotational speed of the gas turbine (12) is kept constant and the output of the gas turbine (12) is adapted without delay when longer-lasting changes of the network frequency occur.

Description

technical field [0001] The invention relates to the field of power plant technology. The invention relates to a method for operating a power plant installation according to the preamble of claim 1 . Background technique [0002] In large power plant installations with powers in the range of more than 100 MW, the generators that generate the current are driven by gas turbines and / or steam turbines and feed the generated electrical power into a network with a predetermined frequency (such as 50 or 60Hz) grid. Large power plant installations usually have a fixed coupling between the (mechanical or aerodynamic) rotational speed of the turbine and the grid frequency. In this case, the output of the generator is connected to the grid in a frequency-coupled manner via a connecting structure, and the generator is driven either directly (single-shaft system) by the turbine or via a mechanical transmission in a speed-coupled manner. The case is driven by the turbine. Such a config...
