Embodiment Construction

[0020] The steam turbine installation 2 shown in FIG. 1 comprises a steam turbine 4 coupled to a generator 6 , a condenser 10 connected downstream of the steam turbine 4 in a water-steam circuit 8 , and a steam generator 12 . The steam turbine 4 consists of a first pressure stage or high-pressure stage 4a and a further pressure stage or intermediate- and low-pressure stages 4b. They all drive the generator 6 via a common shaft 14 .

[0021] The steam generator 12 is connected on its steam outlet side to a steam inlet 18 of the high-pressure stage 4 a of the steam turbine 4 for supplying the working medium AM to the steam turbine 4 . The steam outlet 20 of the high-pressure stage 4 a of the steam turbine 4 is connected via an overflow line 22 to the steam inlet 24 of the medium- and low-pressure stage 4 b of the steam turbine 4 . The steam outlet 26 of the medium-pressure and low-pressure stage 4 b of the steam turbine 4 is connected to the condenser 10 via a steam line 28 . ...

Abstract

A controlling system having a controller which acts on a controlled system as a function of a manipulated variable and a number of controller parameters is intended to provide a given control quality and a given control response in all operating states of the controlled system. For this purpose, the response characteristic of the controlled system is determined in a given time window during operation of the controller by comparing a wavelet transformation of the temporal response of the manipulated variable with a wavelet transformation of the temporal response of a controlled variable of the controller. An instant assigned to the respective wavelet transformation is detected, and the or each controller parameter is set as a function of the response characteristic.

Description

technical field [0001] The invention relates to a method for operating a regulating device with a controller which influences a regulated object with control parameters as a function of controller parameters. The invention also relates to a regulating device for carrying out the method. Background technique [0002] A piece of engineering equipment usually has adjustments which should keep the equipment running as trouble-free as possible. Such a regulating device usually acts on a subordinate regulated object to form a closed regulating loop. In this case, for example, a sensor measures the controlled parameter to be observed at the measuring point of the controlled object. If this regulated variable deviates from a predetermined desired value due to a disturbance, the controller of the regulating device acts with its control parameter on an actuator assigned to the regulated object. The control parameters provided by the controller depend on, in addition to the measured...
