  Hereinafter, an embodiment in which the plant operation system of the present invention is applied to a refinery / factory plant will be described with reference to FIGS.

  FIG. 1 is a block diagram showing the configuration of the plant operation system of the present embodiment.

  As shown in FIG. 1, the plant operation system of this embodiment includes an on-site distributed control system 1A and an off-site distributed control system 1B. The off-site distributed control system 1A is a system that executes operations of the tank yard / receipt / shipment process, and the on-site distributed control system 1B is a system that executes operations such as manufacturing steps other than the tank yard / receipt / shipment process. The off-site distributed control system 1A and the on-site distributed control system 1B are integrated by the integrated control system 10, and operations of each process from arrival to shipment are integrated.

  As shown in FIG. 1, the work management system 3 is connected to an off-site distributed control system 1A and an on-site distributed control system 1B via an integrated control system 10. The work management system 3 creates an operation sequence in the plant for each work.

  Here, “work” refers to a unit of work related to load movement in the entire refinery / factory by a series of items such as charge, rundown, unloading, tank shift, blending, and shipping (shipment). This refers to a flow of a series of work on the production process, which includes not only movements but also on-site and off-site operation targets, modes, and conditions, and is terminated by a property test or the like.

  The work management system 3 includes a configuration receiving unit 31 that receives an input of a plant facility configuration, a configuration storage unit 32 that stores the plant configuration received by the configuration receiving unit 31, and a current facility status in the plant. Equipment status acquisition means 33 to be acquired, work order reception means 34 for receiving a work order, equipment configuration of the plant that satisfies the work order received by the work order reception means 34 and is stored in the configuration storage means 32, and equipment And a sequence creation means 35 for creating an operation sequence corresponding to the equipment situation acquired by the situation acquisition means 33.

  Hereinafter, the function of each means constituting the work management system 3 will be described.

  The configuration receiving means 31 receives an input of equipment configuration for the entire refinery plant in accordance with a user operation on the terminal device 41. This equipment configuration includes all the information related to the plant configuration necessary for creating an operation sequence described later. As an interface used in the terminal device 41, for example, an interface using a flow sheet model is used. According to the flow sheet model, by using a drawing tool to draw a flow sheet that combines objects such as tanks, devices, valves, pumps, berth arms, and the like, it is possible to define equipment constituting the plant and their connection relationship.

  The configuration storage means 32 stores the facility configuration of the plant input via the configuration reception means 31.

  The facility status acquisition unit 33 acquires the current plant status from the off-site distributed control system 1A and the on-site distributed control system 1B via the integrated control system 10. Here, the status of equipment includes information such as equipment failure, provisional change of equipment, and inspection of equipment. For example, each equipment (tank, valve, pump, flow meter, arm, etc. in the path and equipment database) Etc.) and status information of the current state of the device can be added.

  The work order receiving unit 34 receives a business order from the order receiving system 42 and the supply and demand adjustment system 43 or by manual input to the terminal device 41. Here, the business order given from the order receiving system 42, the supply and demand adjustment system 43, etc. is business order information such as destination, oil type, quantity, packing form (ship name, etc.), and delivery date. On the other hand, there are From / To information such as which tank to which berth, scheduled start / end time, operation conditions, yield target, etc. so that actual operation, operation, receipt / shipment work, etc. can be performed at the refinery. Here, what is broken down to understandable information is called “work order”.

The following are exemplified as business orders.
Orders related to receipt / shipment The orders for receipt / shipment relating to ships and pipelines for customers are given to the order receiving means 34 as order information from the order receiving system 42 which performs order management. Further, the order for transfer between refineries is created by the supply and demand adjustment system 43 and is given to the order receiving means 34 as order information.
(2) Refinery orders The refinery orders include not only the off-site oil movement but also the on-site operational targets, modes, and conditions, and are usually produced by the production management department. And the tank balance (tank feed) plan, receipt / shipment schedule, and berth feed plan created by the oil handling department.

  When the work order accepting unit 34 accepts the business order, the work order accepting unit 34 passes the business order to the sequence creating unit 35. Further, the sequence creation means 35 gives the business order to the scheduler 44 together with the equipment configuration stored in the construction storage means 32 and the equipment status acquired by the equipment status acquisition means 33. The scheduler 44 applies the business order to the equipment configuration and equipment status, and the actual From / To information, work contents (amount, mode, operating conditions, yield target, etc.), and work start / end scheduled time. A work order that can be included is created and returned to the sequence creation means 35.

  Next, the sequence creation means 35 creates an operation recipe (operation sequence) based on the work order. The sequence creation means 35 acquires the plant equipment configuration and the equipment status acquired by the equipment status acquisition means 33 stored in the configuration storage means 32, satisfies the work order, and satisfies the plant equipment configuration and the equipment status. Create an operation recipe that can be executed in accordance with. For example, when generating a path, a logic that does not select a device that is in use or is being used during a failure or maintenance according to the status information of each device.

  Here, the operation recipe is a description that defines a specific operation procedure in units of objects such as tanks, devices, valves, pumps, berth arms, and the like. The operation recipe includes path information (routing), start output device and order information, monitoring device information, end output device and order information, and the like. The operation recipe includes all information necessary for control by the off-site distributed control system 1A and the on-site distributed control system 1B.

  FIG. 2 shows a description example of a part of an operation recipe for oil passing.

  In this example, as From / To information, oil passages (routes indicated by dotted lines) from the tank TK102 and the tank TK201 to the TC1 device, respectively, and oil passages (shown by solid lines) from the tank TK101 and the tank TK202 to the TC1 device, respectively. (Route) is described. Moreover, the yield of distillate, the target value of distillate property, the target of oil flow amount, etc. are designated as the operation target. Further, the path information specifies the oil passage route and the state of the pump and the flow meter.

  FIG. 3 shows a description example of a part of the operation recipe regarding the rundown.

  In this example, the From / To information describes that the oil passage (route indicated by the dotted line) from the TC1 device to the tank TK301 is switched to the oil passage (route indicated by the solid line) from the TC1 device to the tank TK302. ing. In addition, the properties of the rundown tank are designated as the operation target. The path information specifies the oil passage and the state of the flow meter.

  The operation recipe created by the sequence creation means 35 is given to the integrated control system 10, and the integrated control system 10 executes control according to the operation recipe as needed via the off-site distributed control system 1A and the on-site distributed control system 1B. While monitoring the progress of the process in units of work.

  As described above, in the plant operation system of the present embodiment, the off-site distributed control system 1A and the on-site distributed control system 1B function as one integrated system. A series of processes from receipt to shipment corresponding to each workpiece is executed based on one operation recipe.

  Hereinafter, as an example of control by the off-site distributed control system 1A and the on-site distributed control system 1B according to the operation recipe, an example of controlling the flow rate and properties of the fluid entering and exiting the tank will be shown.

  As described above, according to the plant operation system of the present embodiment, off-site and on-site are integrated, and a series of processes from arrival to shipment is executed based on one operation recipe corresponding to one work. . Thus, by generating an automatic sequence for each work and performing progress management, not only the work efficiency is improved, but also the operation management of the entire factory including off-site and on-site becomes possible. Further, since data related to operation (data for each mode) can be stored and information management linked to quality can be performed, traceability can be enhanced by analysis that associates operation (work) and quality.

  As described above, according to the plant operation system of the present invention, an operation sequence that satisfies the accepted work order and corresponds to the plant equipment configuration is created, and the operation of the plant is controlled according to the created operation sequence. Therefore, efficient plant operation can be realized by monitoring and managing each work.
