Embodiment Construction

[0031] The present invention will be exemplarily described below with the aid of determining the maximum power of the gas and steam turbine plant. However, the invention is not limited to use in gas and steam turbine plants. In particular, it can also be used in gas turbine plants without a downstream steam turbine.

[0032] The gas and steam turbine plant 1 schematically shown in FIG. 1 includes a gas turbine plant 1a and a steam turbine plant 1b. The gas turbine 1a has a gas turbine 2, a compressor 4, and at least one combustion chamber 6 connected between the compressor 4 and the gas turbine 2. The fresh air L is sucked by the compressor 4, compressed and fed into one or more burners of the combustion chamber 6 through the fresh air duct 8. The introduced air is mixed with the liquid or gaseous fuel B introduced through the fuel conduit 10, and then the mixture is ignited. The combustion exhaust gas formed in this process forms the working medium AM of the gas turbine devic...

Abstract

A method for determining a current maximum output (Pmax) of a power station plant, in particular, a gas turbine plant or a gas and steam turbine plant, is disclosed, comprising the steps: recording at least one measured value (xi) influencing the maximum output (Pmax), recording a conversion value (f(xi)) from the at least one recorded measured value (xi), which represents the change of current maximum output (Pmax) in relation to a reference output (Pref), and converting the reference output (Pref) into the current maximum output (Pmax) by means of the conversion value (f(xi)).

Description

Technical field [0001] The invention relates to a method for determining the current maximum power of a power plant, in particular a gas turbine plant or a gas and steam turbine plant. In addition, the invention relates to a regulating device for regulating power generation equipment, in particular gas turbine installations or gas and steam turbine installations. Background technique [0002] In the grid, the grid operator guarantees the balance between the load, that is, the required power and the supplied power. The difference between the load and the power provided results in a change in the frequency of the grid, which has a negative impact on the operation of the grid and may lead to a complete breakdown of the grid in the worst case. [0003] In order to be able to react quickly when there is a sudden imbalance between the load and the power provided, the grid operator purchases reserve power from the generator, the so-called Regel reserve. The power station participating i...
