Description
DESCRIPTION
DECISION SUPPORT SYSTEM FOR POWER PLANTS Field of the Invention
The invention relates to a new visual-based application providing a decision support system on power plants. Prior Art
Electricity and steam required for refinery operations are generated by Power Plants located inside the refinery. The fuel cost of the Power Plants is over 185 million TRY/year, amounting to about 35% of the fuel cost of the entire refinery.
Non-interruption of the processes in the refineries is the most important point in terms of safety and economical aspects. In this respect, it is vital that energy and steam required for continuing processes in the refineries be generated by internal sources. In view of the above, it is highly advantageous that all refineries have a power plant.
Yet it is not sufficient that power plants are available in a refinery; it is a must that these are managed accurately. The object of the management of power plants is not only to enable generation of the entire energy by the internal sources, but also to make an electricity purchase-sale balance when economically appropriate conditions are obtained.
Manuel methods or outsourced software are currently used in a refinery for deciding on the equipment to be utilized and for determining the amount and type of the fuel to be consumed. This method not only results in time delays but also paves the way for human- related errors.
With the currently used method, it is possible to make instant optimization works whereas it is not possible to foresee the actions to be taken during the day. The method used can only be used by certain experts, thereby resulting in loss of time and dependency on individuals in reporting.
In the state of the art, operational method of the power plants in refineries is performed via a matrix-defined model. This matrix is created on Excel, which is a method that can only be used by certain persons and difficult to update. The model used can only make instant optimization, but time-related constraints cannot be defined.
In prior art, a number of systems are developed in order to overcome the above- mentioned drawbacks. One of them is "Mixed Integer Nonlinear Programming Model for Optimal Synthesis and Operation of Utility Plants" " (March, 1998) (J. C. Bruno, F.Fernandez, f. Castells, I. E. Grossmann). In this study, nonlinear programming has been utilized that provides an instant optimization. The fact that it is not linear results in loss of time in solving the problem, and in case of an incidence, it takes time to operate it to take action.
As a result, developments are sought in management systems of the power plants and thus new configurations are needed that would eliminate the above-mentioned drawbacks and provide solution to the existing systems.
Object of the Invention The present invention relates to a visual-based application providing a decision support system on power plants, which fulfills the above-mentioned requirements, eliminates all drawbacks and provides some additional advantages.
With the inventive application, it is aimed that an optimization be made for deciding which equipment will be switched on or off for electricity and steam generation so that energy reliability is ensured, at which load the operation will be enabled and the amount of the fuel mixture to be used, and thus reducing energy costs.
As another advantage of the invention, it is aimed at providing a decision support for purchase and sale of electricity for purposes of reducing costs by providing access to day- ahead energy market, whereby in case of sale of the low-costly produced electricity to the market or increase in the need of the refinery, electricity can be supplied from the market instead of producing electricity at high cost. The application comprises a user-friendly interface and has an online connection with the process data of the refinery.
The new application prepared allows easy modeling and update thanks to the optimization analyzer integral with the interface. Furthermore, with this new software to be implemented, the power plants may be modeled with all the components, time-related constraints can be defined easily and an optimization can be made with a cost function reflecting the facts. Another advantage of the application is that it allows feasibility and scenario analysis.
In order to obtain all the above-identified advantages which will be clear from the following detailed description, the present invention is a visual-based system providing a decision support system on power plants, characterized by comprising defined flow diagrams and/or a flow diagram designer that will allow preparation of a network of power plants, a model creator that will prepare an optimization algorithm in a language understandable by an auxiliary software, and a reporter comparing the results obtained with analysis of the said algorithm by the auxiliary software with the field data obtained from the data sources by the data adapters.
In preferred embodiments of the invention, the said flow diagram designer comprises a drag-and-drop diagram that will allow creation of the network of power plants, and the said flow chart designer is improved in that it comprises the step of defining model parameters and constraints that will allow creation of the network of power plants.
Structural and characteristic features of the invention as well as all the advantages will be clear from the following drawings and detailed description given with reference to these drawings, as a result of which any evaluation should be made taking into account of these drawings and detailed description.
