The invention relates to a method for operating an industrial scale, in particular energy installation, in which a number of operating parameters of the installation, which is characteristic for the respective operating state of the technical installation, and, respectively, selected for a number of selected components of the technical installation of a number of components parameters that are relevant for the respective components are controlled and stored in the storage device, whereby the aforementioned components or each selected component, according to need, based on the stored operating parameters of the installation and/or saved respective operating parameters of the components is determined by the rate of fatigue characteristic of the current state of fatigue of the corresponding component. It refers also to a control system for installation on an industrial scale, in particular power plants, which in terms of its components, such as storage devices, blocks, assessment, etc. made with the possibility of determining the values of fatigue for installation components and, thus, with implementation of the above method. In industry occur in a variety of industries technical installation or setup of the industrial is asstube, which are used, for example, for the manufacture of certain products, for processing or beneficiation of raw materials, for automated performance of first run manually operations or to develop, in particular, electricity. Ready industrial installations, such as power plants, are composed in General of a plurality of components of the installation that implement separate functions relevant industrial installations. Many of these installation components are subjected during their service life mechanical or due to the production of wear. During the lifetime of the technical installation of the wear components installed already during the design represents a significant aspect, since the excess border fatigue the technical functioning of the installation or, at least, the corresponding component is no longer guaranteed. In particular, in power plants parts or installation components, such as boilers, steam generators, batteries, pipelines, are exposed to changing mechanical stresses on the basis of changes in their environmental parameters, such as, for example, pressure and temperature. These variables load, also referred to as load cycle power plants, which are typically caused by changed the eating state energy installation, as, for example, by raising or lowering the power, as a rule, lead to potentially significant loading of the materials of the components and to the so-called fatigue component, which is above a specific limit and also can lead to component failure. In particular, due to this fatigue service life or the maximum period of operation of the respective components of power plant or industrial components installation is limited. For these reasons, the fatigue details for selected components of the installation when planning the installation of industrial scale, and planning cycles of repair and maintenance is taken into account that, under appropriate circumstances, be able to timely replacement of the component before failure details. For the appropriate accounting for such phenomena fatigue when planning installations usually during construction or calculation of the components of the power plant to guarantee a minimum service period of the respective components or parts provides pre-defined, consisting of a limited number of types of load cycles a set of loads, which, for example, includes a specified number of hot, zapuska is, warm starts and cold starts with respectively predetermined modes of operation of the power plant. For these standardized types of load cycles, then for each type of load cycle are determined by the corresponding values of fatigue in their respective components, and are typically used relatively costly methods of calculations, such as calculation of finite elements. Taking into account the obtained results is the calculation of the corresponding component of the installation, as a rule, so that General fatigue, some of the individual values of fatigue and the amount stipulated by the load cycles on the type, the part or the corresponding component does not exceed the specified limit values of fatigue, is still considered valid. However, considering fatigue in the individual parts or components of the actual component behavior can be forecasted insufficient. In particular, typically the actual mode of operation of industrial scale or, in particular, the power plant is more flexible and variable than in the calculation, since the mode of operation of power plants should be consistent, for example, with the current requirements of the load, So to have the opportunity properly to consider is actually manifested by fatigue when planning maintenance and inspection of power plants, in power plants and other installations of the industrial scale is generally controlled by the corresponding fatigue details for the selected installation components. As the fatigue of the parts, as a rule, cannot be measured directly, are usually measured and controlled by the pressure and temperature characteristics of the respective environmental conditions of the corresponding component are then calculated variables of voltage, caused by the changes of pressure and temperature, the corresponding component. The actual values for the stresses in the components then are cycles of the variable load, the height and the number of load cycles are compared with limit values. As a result, in the end, is determined by the so-called indicator of fatigue, which is the indicator of the fatigue of the part or of the corresponding component, which may specify, for example, the proportion of component life. With these concepts it is possible for the selected components of the power plant or components of the industrial installation to determine the fatigue manifested throughout their full use in the work, and to consider it is when planning maintenance and inspection. Relevant principles established, for example, in the document DIN EN 12952-4:2001-10 "Wasserrohrkessel und Anlagenkomponenten, Teil 4: Betriebsbegleitende Berechnung der Lebensdauererwartung, deutsche Fassung EN 12952-4:2000". In any case, during the operation of similar plants on an industrial scale, in particular power plants, for security reasons, should, on the one hand, to draw attention to the fact that maintenance and, if necessary, replacement of worn out or fatigue resistant components or parts in each case must be brought promptly before a breakdown or failure of the corresponding component. But, on the other hand, there is a desire for these interventions associated with maintenance and repairs in the installation of industrial scale, in order to avoid unnecessary idle times and for particularly economical method of operation, to take particularly in line with the needs so that the details really were replaced only when they are still relatively small residual service life. Moreover, for a particularly effective and economical operation of installation operating mode of the installation concerned is selected in such a resource-saving way that the wear and fatigue of components and parts are supported by capabilities small. Therefore, the basis of the invention Lee the t task is therefore to improve a method for operating an industrial scale of the aforementioned type, when defining indicators of fatigue, specific to the selected installation components, in order, while maintaining the set standards of reliability, provided a particularly long service life of individual parts or components, and promoted, especially to meet the needs of the planning of inspection and maintenance. In addition, for the implementation of this method should be proposed especially suitable control system for installation on an industrial scale. In the way this task in accordance with the invention is solved in that, on the basis of the indicator of the fatigue characteristic of the current state of fatigue for components or each selected component, on the basis of control parameters, characteristic under changing conditions, is determined corresponding to the predictive value of fatigue. This invention proceeds from the fact that for particularly resource-saving and, thus, enabling the service life of components used and details of the mode of operation of industrial scale or power plant should be involved certain indicators of fatigue, in addition to the pure diagnostic details, current mode of operation. For this purpose, based on certain actual values for the currently tired of the particular corresponding component or corresponding parts, type extrapolation taking into account the intended mode of operation to establish the predictive value for fatigue details, which, for example, can be used as an auxiliary parameter to determine the need for repair or maintenance. However, this change of state is, in particular, the change of the load of the power plant and may, in particular, to be the process of starting or actuate the power plant. As the operating parameters that should be considered to determine appropriate indicators of fatigue, must be provided, the preferred way, on the one hand, specific components of the operating parameters or operating parameters of the components, which are the preferred way include indicators for ambient pressure, ambient temperature and/or humidity of the environment of the component or the relevant parts. Alternatively or additionally, the preferred way for installation status of industrial scale or power plants are defined or measured in whole or relevant characteristic operating parameters or operating parameters of the installation, which is the preferred way include pok the indicators for the state of activation of the unit and/or the rated power. From the combination of these parameters can then be determined by the values of pressure and temperature that act locally to the appropriate component or corresponding part, and which, ultimately, point to mechanical stress and, thus, the resulting fatigue details. To be able to determine particularly reliable indicators for fatigue details, in further preferred implementation when appropriate indicator of fatigue and the corresponding predicted values of fatigue for the corresponding component are taken into account characteristic parameters of the component. The parameters of the component are preferred in particular taken into account the material, geometrical dimensions and/or which is decisive for the calculation of fatigue designated measurement of pressure and temperature in the corresponding component. Due to the complexity of fatigue fundamental processes usually when accessing resources provided vicious accurate calculation of indicators or parameters is impossible or impractical. In order for treatment only to limited computational capabilities to be able to provide particularly reliable indicators or parameters, the preferred way on what I determine the corresponding forecast values of fatigue characteristics are taken into account trends for the values of the temperature and/or pressure inside the corresponding component. The characteristics of the trend preferred by way determined from thermodynamic modeling of the installation, and if necessary, can be accessed saved experienced knowledge or prepared experimental values. To ensure that the cost of detecting and processing support is particularly low and, thus, a particularly effective way to facilitate diagnostics installation and management, in additional or alternative preferred implementation of purposefully taking into account the knowledge that due to wear or due to fatigue failure of the components or parts, as a rule, the first and only manifests itself on the components most affected by wear or fatigue. Consideration of the state of wear or fatigue of the corresponding component when planning maintenance or repair may, therefore, be taken particularly effective way due to the fact that the evaluation focus on the components that are expected to be the most affected by fatigue or wear. To enable this, the preferred way as the so-called "lead compound" is identified for priority consideration when forecasting the installation of the component or part, Kotor, which has the highest specific predictive value of fatigue from all of the estimated components. The preferred way is the predictive value of fatigue leading component is used as a criterion for entering events on repair and maintenance. In a particularly preferred implementation targeted assessment of the state of fatigue of the parts or components involved not only for the corresponding scheduling needs repair or maintenance, but also for optimization of the mode of operation of industrial scale in the sense of particularly resource-saving and prolonging the service life of the operation. For this preferred manner, based on the current state of your installation type scenario planning, analysis of various scenarios of changes of state or changes of the load under which the installation could be operated in the near future. However, based on the current actual status of the power plant may, for example, relatively rapid, transient increase in capacity compared with a relatively slowly applied, the gradual increase in power. For this alternative under changing conditions then the preferred way determined the predictive value of fatigue and compared with each other, and on the basis of this comparison, the selected one of the possible situations or processes of the change of the load, which leads to the smallest load setup that differs the least predictive value of fatigue. Comparison between different possible changes of state or changes in the load may be based on the forecasted values of fatigue of the corresponding lead of the component or on the basis of the block of predictive values of fatigue for many of the relevant components. The control system for installation on an industrial scale, in particular power plants, with the storage device in which is stored a number of operating parameters of the installation, which is characteristic for the respective operating state of the technical installation, and a number of operating parameters of the components that are relevant for a number of selected components of the technical installation, and which data is connected with the evaluation unit, which is configured to determine, according to needs, an appropriate indicator of the fatigue characteristic of the current state of fatigue of components or each of the selected component based on the stored operating parameters of the installation and/or saved respective operating parameters of components, this problem is solved the fact that the evaluation unit is arranged to determine for components or each of the selected component with the relevant predicted values of fatigue, based on the indicator of the fatigue characteristic of the current state of fatigue, based on the control parameters, characteristic for the envisaged change of state. For a particularly reliable and accurate estimates in a storage device stored thermodynamic model installation of industrial scale or energy installation on the basis of which it is possible especially reliable estimation of loads due to temperature and pressure in individual components or parts. Provide the advantages of the invention consist in particular in that by attracting a fatigue analysis to provide the corresponding forecast values is possible and is particularly favorable corresponding to the needs of planning for maintenance and inspection of the unit on an industrial scale. In addition, due to the strategic assessment components fatigue or expected components of fatigue in individual components or parts of the installation of industrial scale can get the change of load or change of state in respect of externally defined boundary conditions provides the ability to globally considered particularly resource-saving mode installation. An example of carrying out the invention explained more with Silkina drawing, which is a schematic representation of a control system for installation on an industrial scale, in particular power plant. This is a schematic representation of the control system 1 contains a lot of detail not shown modules or components, which are widely distributed and are conventional for use in installations of the industrial scale and, in particular, in power plants. In particular, the power plant is equipped with many measurements or sensors through which the process is monitored component parameters and details and, if necessary, are archived. Among these sensors and measurement contains numerous sensors and measurements, by means of which the process is controlled fatigue of the individual components or parts of the power plant. To do this, the system 1 control, along with other components, includes a storage device 2, which is purposefully made for archiving and providing measured values and parameters that are defined within the control of fatigue. In particular, in the storage device 2 stored component parameters selected for monitoring fatigue as particularly relevant components and parts, and, in particular, each relevant details or CA is home relevant component is set in accordance with its own parameter set, contains data for materials, dimensions and which is decisive for the calculation of the fatigue of the relevant components designated measurement of pressure and temperature or the positioning data. In addition, in the storage device 2, according to necessity, remain controlled by the measured values, and, on the one hand, involves a certain number of work installation parameters, characteristic of the operating state energy facilities, such as, for example, indicators for the condition of load, rated load, etc. in Addition, for selected components of the power plant also saved the relevant operating parameters of the components, and the type definition of the measured values are stored continuous environment, such as air pressure, air temperature, air humidity for controlled items, as well as their temperature and pressure. Typical of this measured value M is determined in block 4 determination of measured values, which, for its part, from data connected with the respective sensors, and, if necessary, stored in the storage device 2. In addition, block 4 determine the measured value passes some data in unit 6 assessment, in which, if necessary, define the parameters in which Talosto for the corresponding parts or components. However, unit 6 assessment is made not only to determine the current actual status for the corresponding fatigue details, but, in addition, unit 6 assessment identifies additional components or each component selected more appropriate predictive value of fatigue, which is based on the anticipated changing conditions, such as process load change, etc. based on the current state of fatigue of the corresponding component, describes the expected state of fatigue after an appropriate change of state. To be able to hold such a forecast for the expected fatigue detail or detail, the system 1 contains a control unit 8 input, through which you can enter target parameters E, characteristic, respectively, of the analyzed transition. In particular, the analysis of changes of load are to be entered installed capacity of the power plant and the time interval specified to achieve the intended power level. Unit 4 definition of measured values and the block 8 input data is connected to the first module 10 modeling unit 6 assessment. In the first module 10 modeling of the measured environmental conditions and operating parameters of the installation, and entered in block 8 input target the parameters to be evaluated changing conditions or load pre-calculated required to achieve the respective target parameters the program use for power plant and the characteristic trend of the relevant process parameters, such as pressures, temperatures and expenses. This takes into account thermodynamic modeling and/or thermodynamic model of the power plant, and thermodynamic model stored in the first module 10 simulations. Thermodynamic modeling in the first module 10 simulation produces as a result of, among other parameters, in particular the characteristics of the trend of temperatures and pressures of the environment in a controlled parts or components. The results are sent to the second module 12 simulation, in which the characteristics of the trends for the pressures and temperatures in the corresponding component or corresponding parts are determined by the characteristics of the trends of the temperatures inside the wall and temperatures in the middle of the wall for testing parts. This follows when referring to the design parameters and materials, which are stored in the storage device 2. In the third module 14 modeling using certain temperatures and pressures in the parts or components are determined by the characteristics of the stresses in the walls of the components, whereby, for example, if necessary, also to parameters or blocks of data that are specific to items stored in the storage device 2. In the trail of the next fourth module 16 modeling of certain characteristics voltage for each controlled part or each of the component being controlled is determined by the component fatigue for the analyzed transition or load change. In the subsequent fifth module 18 simulation is determined, finally, that a part or the component for which/which is the sum of the current index of fatigue, which is stored in the storage device 2, and defined in the previous fourth module 16 modeling additional component fatigue caused evaluated by the change of state or change of the load is the greatest. This item or this component is identified as "the leading component and subsequent estimates is used as the relevant item. The predictive value of fatigue leading component is considered as an expected component of fatigue for the entire installation and is issued in block 20 of the issue for further assessment or to inform staff. Thus, with proper definition of the various prognostic indicators of fatigue, for example, maintenance or repair of the plan, in particular, in accordance with needs, the expected fatigue leading component is compared with the additional limit values. Additionally, or alternatively, you can also type scenario planning to model many different changes of state or changes of the load, and on the basis determined the military forecast values of fatigue is selected the script, load change and subject to further work installation which leads to the smallest additional load. 1.
