- the guidance device 1 for selecting a safety factory which is an embodiment of the present invention, is a device for creating and presenting a safety operation plan for a plurality of factories in the power system of a steel mill, and is a personal computer or a device. It is composed of a general-purpose information processing device such as a workstation.
- the guidance device 1 for selecting a safety factory includes an input unit 2, a database (DB) 3, a calculation unit 4, and a display unit 5.
- the input unit 2 is an operation input means for the calculation unit 4, and is composed of an input device such as a keyboard, a mouse pointer, and a numeric keypad.
- the input unit 2 outputs an operation input signal to the calculation unit 4.
- the database 3 stores information on the power supply and demand plans of a plurality of factories to be managed in a form that can be read by the calculation unit 4.
- the arithmetic unit 4 is composed of, for example, a processor including a CPU (Central Processing Unit) and a memory (main storage unit) including a RAM (Random Access Memory) and a ROM (Read Only Memory).
- the calculation unit 4 loads a computer program into a work area of the main storage unit and executes it, and controls each component or the like through the execution of the computer program to realize a function that meets a predetermined purpose.
- the display unit 5 is composed of a general-purpose display device such as a liquid crystal display device, and displays and outputs various information according to a control signal from the calculation unit 4.
- the guidance device 1 for selecting a safety factory having such a configuration calculates the safety operation plan of the factory so as to fall within the power range in which power can be supplied by executing the guidance processing shown below, and the operating factory or non-operating factory or non-operation factory. Present the operator with the combination of operating plants.
- the operation of the guidance device 1 selected by the safety factory when executing this guidance process will be described with reference to the flowchart shown in FIG.
- FIG. 2 is a flowchart showing a flow of guidance processing according to an embodiment of the present invention.
- the flowchart shown in FIG. 2 starts at the timing when the execution command and the set value of the guidance process are input via the input unit 2, and the guidance process proceeds to the process of step S1.
- step S1 the calculation unit 4 reads information about the power supply and demand plan of the factory to be managed from DB3, and based on the read information, the planned value of the power supply and demand of the factory to be managed within a predetermined period.
- the planned value of the power supply and demand of the factory may be a fixed value determined in advance, a predicted value obtained by a regression equation based on a rolling plan or a steelmaking plan of a steel mill, or the like.
- step S2 the calculation unit 4 operates the factory for safety operation within a predetermined period under the condition that the power consumption of the factory is the maximum within the range of the private power generation amount based on the set value input from the input unit 2.
- the amount of electric power used in the factory does not necessarily have to show the maximum value, and may be a value asymptotic to the maximum value. Further, in addition to the condition where the amount of power used in the factory is the maximum, the condition where the amount of power sold is the maximum may be set.
- step S2 is completed, and the guidance process proceeds to the process of step S3.
- the calculation unit 4 sets the factory as, for example, a group of factories that operate, a group of factories that stop operation, a group of other factories, etc., based on the set value input from the input unit 2. Determine whether to group. As a result of the determination, when the factories are grouped (step S3: Yes), the calculation unit 4 advances the guidance process to the process of step S4. On the other hand, when the factories are not grouped (step S3: No), the calculation unit 4 advances the guidance process to the process of step S5.
- the calculation unit 4 sets the constraint conditions at the time of calculating the security operation plan for grouping the factories. Specific examples of constraints will be described later. Multiple factories are pre-classified into a group of factories that operate, a group of factories that stop operation, and a group of other factories, and the factories that are classified into the group of other factories are active / non-operating factories. By calculating the combination of selections, it is possible to facilitate the selection of active and non-operating factories.
- the factories may be grouped according to the priority of operation. Specifically, in the blast furnace of a steel mill, raw materials are used as hot metal to hot metal, but once the operation of the blast furnace is stopped, it takes a long time to recover, so we want to maintain the operation of the blast furnace. Moreover, since it is necessary to supply not only electric power but also oxygen to the blast furnace, it is necessary to keep the oxygen plant in operation so as not to run out of oxygen. Furthermore, it is necessary to keep the blast furnace blower in operation in order to continue the supply. Therefore, the blast furnace, the oxygen plant, and the blast furnace blower may be classified into a group having a high priority of operation.
- factories may be grouped according to the amplitude of power fluctuations and the magnitude of the cycle. Specifically, in a rolling mill, power consumption increases when rolling semi-finished products such as continuously cast slabs, but power consumption decreases when idling, so power fluctuations occur in a relatively short cycle. The amplitude increases. On the other hand, in factories and business establishments that operate constantly, the fluctuation of electric power has a relatively long cycle and the amplitude becomes small. Therefore, these factories may be grouped and treated as a group of factories having a constant power.
- step S4 the process of step S4 is completed, and the guidance process proceeds to the process of step S5.
- step S5 the calculation unit 4 determines whether or not to suppress the number of changes in the factory selection between operation and non-operation based on the set value input from the input unit 2. As a result of the determination, when the number of changes in the operation / non-operation factory selection is suppressed (step S5: Yes), the calculation unit 4 advances the guidance process to the process of step S6. On the other hand, when the number of changes in the operation / non-operation factory selection is not suppressed (step S5: No), the calculation unit 4 advances the guidance process to the process of step S8.
- step S6 the calculation unit 4 sets the constraint condition at the time of calculating the safety operation plan when suppressing the number of changes in the factory selection between operation and non-operation. Specific examples of constraints will be described later. By suppressing the number of changes in the factory selection between operating and non-operating factories, it is possible to reduce the labor of the operator who switches between operating and non-operating factories. As a result, the process of step S6 is completed, and the guidance process proceeds to the process of step S7.
- step S7 the calculation unit 4 uses the planned value of the power supply and demand of the factory registered in the process of step S1 to perform the safety operation of the factory that satisfies the calculation conditions and the constraint conditions set in the process of step S2. Calculate the plan. Then, the calculation unit 4 calculates a combination of operation / non-operation factory selection in a time zone within a predetermined period from the calculated security operation plan. As a result, the process of step S7 is completed, and the guidance process proceeds to the process of step S9.
- step S8 the calculation unit 4 uses the planned value of the power supply and demand of the factory registered in the process of step S1 to perform the safety operation of the factory that satisfies the calculation conditions and the constraint conditions set in the process of step S2. Calculate the plan. Then, the calculation unit 4 calculates a combination of operation / non-operation factory selection in a certain time zone or a certain time cross section (time point) from the calculated security operation plan. As a result, the process of step S8 is completed, and the guidance process proceeds to the process of step S9.
- step S9 the calculation unit 4 displays the information (guidance screen) regarding the combination of the active / non-operating factory selection calculated in the process of step S7 or step S8 on the display unit 5.
- the process of step S9 is completed, and a series of guidance processes is completed.
- the power consumption of the factory is maximized within the range of the private power generation amount.
- the present invention has been applied to the process of selecting a factory to be operated or not operated.
- the actual value is used as the power value of the factory assuming an ideal situation where the power consumption of the factory can be accurately grasped. Based on this premise, if (a) the number of changes in the factory selection between operating and non-operating factories is not suppressed, (b) the number of changes in the factory selection between operating and non-operating factories is suppressed, but the factories are not grouped. For the three cases of (c) the case where the number of changes in the factory selection is suppressed and the grouping of factories is carried out, an integer programming problem was created and the combination of the factory selections of operation and non-operation was calculated. ..
- the problem (b) is set by adding the following constraints to the problem (a).
- the constraint shown below is that a factory cannot be selected as a factory to switch between operating and non-operating unless the operating time and downtime last for 4 hours.
- problem (c) when grouping factories by suppressing the number of changes in factory selection, problem (c) was set by adding the following constraints to problem (b).
- the grouping of factories was carried out so as to prioritize the factories considered to be the minimum necessary for the operation of the steelworks.
- Figure 3 shows the number of changes in factory operation / non-operation in each case as a calculation result of factory selection for operation / non-operation in a certain time zone (20 hours).
- the operation / non-operation of the factory is changed every hour, but in the case of (b), the number of changes is reduced by about 30% compared to the case of (a), and in the case of (c), the change is made.
- the number of times is reduced by about 80%.
- the operating / non-operating state of each factory shown at time 0 to time 3 is set as the initial state, and the operating / non-operating state of the factory at each subsequent time in each case is shown.
- 1 indicates selection (operation) and 0 indicates non-selection (non-operation). Any state is assumed as the initial state, but here it is assumed that all are not selected.
- the shaded area indicates the time when the change of operation / non-operation is occurring.
- FIG. 7 shows an example of the guidance screen display. The operator adjusts the operating state of the factory by referring to the guidance screen shown in FIG. In the examples of FIGS.
- the operation / non-operation of the factory is selected on the assumption that the relationship between the factories does not need to be considered. Actually, there is an interdependent relationship between the operations between factories, and problems may occur if you do not select operation / non-operation at the same time. In such a case, the grouping shown in FIG. 7 (c) may be carried out.
- FIG. 7 by designating a group of factories that are essential for the operation of the steelworks as a priority group, the operation of each factory including other factories that perform the processing that is essential for the operation of each factory is performed. -You have selected non-operation. For this reason, the factory is not selected so that the same industry of the steelworks cannot be performed, the operation of the steelworks can be continued, and the operation / non-operation of the factory can be selected within the range of power supply.
- a guidance device and a guidance method for selecting a safety factory capable of calculating a factory safety operation plan so that the power supply is within a possible range and presenting a combination of operating factories or non-operating factories are provided. Can be done. Further, according to the present invention, it is possible to provide a method of operating a factory in which the factory can be operated so as to fall within the range of electric power that can be supplied with electric power.
