At present, iron and steel enterprise's energy emulation spininess of research is to certain energy medium in the concrete enterprise both at home and abroad, and its simulating scenes establishes following several mode: according to the enterprise practical production schedule; According to the definite plurality of proposals of starting or stoping of define equipment.The problem that its simulating scenes is set up is: how directly according to the enterprise practical production schedule, the energy device that relates to is limited, and for different enterprises, versatility embodies inadequately.
Summary of the invention
The object of the present invention is to provide a kind of iron and steel enterprise energy simulating scenes preparation method, not only can work out out the simulating scenes of the needed logistics variation of iron and steel enterprise energy emulation platform, product technique change, unusual service condition, overhaul of the equipments, and this scene is applicable to the energy resource system emulation of a plurality of iron and steel enterprises, thereby makes emulation platform can simulate the use, conversion, transmission ﹠ distribution of each iron and steel enterprise's energy medium under the various scenes, the situation of storing and diffusing.
By this method, can work out out simulating scenes such as the needed logistics variation of iron and steel enterprise energy emulation platform, product technique change, unusual service condition, overhaul of the equipments, make emulation platform can simulate the diffusing and the outsourcing situation of load distribution, the energy of recovery, the energy device of use, the by-product energy of the energy under the various scenes.
The present invention sets about from iron and steel enterprise's energy fluctuation changing factor, consider contents such as steel mill of different iron and steel enterprise pattern, device type, product type, processing route, production cycle, equipment state, unusual fluctuation factor, logistics factor, work out out the simulating scenes that can reflect above factor.
The present invention includes following steps: model construction, iron and steel enterprise's modeling, scene initialization, scene establishment, scene result's output; Wherein model construction and iron and steel enterprise's modeling are the bases of scene establishment, and the scene initialization is the starting condition of scene establishment, and scene result's output is the net result of scene establishment.
Model construction in the method is the basis of scene establishment, provides the method for expressing of general relatively iron and steel enterprise, the production run difference of bringing in order to solve iron and steel enterprise's different mode, device type, product type and processing route.Device model and product model have mainly been constructed, two class models are by the attribute and the parameter of model, and association is carried out in the definition of processing route, the wherein unit in the product model, output product specification, corresponding raw material specification attribute, be associated with the output specification limit in the device model, the operation chain that defines in the processing route is the set of operation attribute in the device model.
The parameter value of each class model is determined in iron and steel enterprise's modeling according to the iron and steel enterprise of concrete actual iron and steel enterprise or design.For device model, at first determine the quantity of model, next defines the basic parameter and the input of model.Product model is then directly determined its parameter.By changing model parameter, can be to different iron and steel enterprise's modelings, thus the fluctuation situation of the energy that the variation of performance business equipment type, product type, processing route causes.
The scene initialization is to comprising the scene initialization with operating mode and logistics correlative factor, and the definition of simulation parameter.Some equipment of operating mode initialization definitions is in the operating mode (maintenance or fault) of certain time period, and particular content comprises: device name, operating mode (maintenance or fault), this operating mode start time point and concluding time point.The initialization of logistics correlative factor comprises: name of product, and product plan output, the rate of load condensate of each equipment (defaulting to the designed capacity of equipment), wherein load rate of plant is used for representing that production task under some external condition is not full and the energy consumption difference that causes.In the definition of name of product and product plan output, can define a plurality of products simultaneously, can carry out emulation to the situation that iron and steel enterprise's multiple product is produced simultaneously like this.The simulation parameter definition comprises: emulation start time, simulation step length.
