A method and apparatus for detecting, as well as for power regulation in a system, in particular a combined gas - and steam turbine plant

摘要

Method for detecting, as well as for power regulation in the case of a plant with at least one drive, with the at least two drives is connected in each case via a line shafting, on the basis of a predeterminable power - desired value, characterized by the,that in each case a drive - internal detecting is carried out by drive internal operating variables are determined,that a power take-off - internal detecting is carried out by power take-off - internal operating variables are determined,that for the detection of expansions due to torsion along which the drives with the power take-off shaft lines connecting the measuring pick-ups are provided, whose measurement signals in combination with the rotational speed and the internally acquired performance quantities for detecting a is - power of the entire system can be used,that the determined is - power of the contact with the power - desired characteristic value is compared, andas a function of the desired / is - comparison of the drives for the targeted change in power can be controlled.
