Hereinafter, the present invention will be described through embodiments of the invention with reference to the drawings, but the following embodiments do not limit the invention according to the claims, and are described in the embodiments. Not all combinations of features are essential to the inventive solution. The same or equivalent constituent elements, members, and processes shown in each drawing are denoted by the same reference numerals, and duplication of description will be omitted as appropriate.

FIG. 1 is a schematic diagram showing the overall configuration of the plant according to this embodiment. First, using FIG. 1, the configuration of a plant 1, which is a series of target facilities targeted by the present embodiment, will be described. The plant 1 is, for example, a power plant (combustion plant) including a circulating fluidized bed boiler (circulating fluidized bed type), which burns fuel while circulating a circulating material such as silica sand that flows at high temperature to generate steam. It is equipped with a boiler that allows As the fuel for the plant 1, in addition to fossil fuels such as coal, for example, non-fossil fuels (woody biomass, waste tires, waste plastics, sludge, etc.) can be used. Steam generated in plant 1 is used to drive turbine 100 . Plants targeted by the present embodiment are not limited to power plants including boilers and incineration plants, and may be plants such as chemical plants and wastewater treatment plants from which process data can be acquired.

The plant 1 is configured to burn fuel in a furnace 2, separate a circulating material from exhaust gas by a cyclone 3 functioning as a solid-gas separator, and return the separated circulating material to the furnace 2 for circulation. there is The separated circulating material is returned to the lower part of the furnace 2 via a circulating material recovery pipe 4 connected below the cyclone 3 . The lower portion of the circulating material recovery pipe 4 and the lower portion of the furnace 2 are connected via a loop seal portion 4a having a narrowed flow path. As a result, a predetermined amount of circulating material is stored in the lower portion of the circulating material recovery pipe 4 . The exhaust gas from which the circulating material has been removed by the cyclone 3 is supplied to the rear flue 5 via the exhaust gas passage 3a.

The boiler is equipped with a furnace 2 for burning fuel and a heat exchanger for generating steam using the heat obtained by combustion. A fuel supply port 2a for supplying fuel is provided in the middle part of the furnace 2, and a gas outlet 2b for discharging combustion gas is provided in the upper part of the furnace 2. As shown in FIG. Fuel supplied to the furnace 2 from a fuel supply device (not shown) is supplied to the interior of the furnace 2 through a fuel supply port 2a. Furnace wall tubes 6 for heating boiler feed water are provided on the furnace wall of the furnace 2 . Boiler feedwater flowing through the furnace wall tube 6 is heated by combustion in the furnace 2 .

In the furnace 2, solid matter containing fuel supplied from the fuel supply port 2a is fluidized by combustion/fluidizing air introduced from the lower air supply line 2c, and the fuel is fluidized at about 800 to 900, for example. ℃. Combustion gas generated in the furnace 2 is introduced into the cyclone 3 while entraining the circulating material. The cyclone 3 separates the circulating material from the gas by centrifugal separation, returns the separated circulating material to the furnace 2 through the circulating material recovery pipe 4, and transfers the combustion gas from which the circulating material has been removed to the exhaust gas flow path 3a. to the rear flue 5.

In the furnace 2, part of the circulating material called furnace bed material stays at the bottom. This bed material may contain bed material having a coarse particle size that is unsuitable for circulation and contaminants from exhaust combustion. Therefore, in the furnace 2, the in-furnace bed material is continuously or intermittently discharged to the outside from the discharge port 2d at the bottom in order to suppress poor flow. The discharged bed material is supplied to the furnace 2 again or discarded as it is after removing unsuitable materials such as metals and coarse grains on a circulation line (not shown). The circulating material in the furnace 2 circulates in a circulating system composed of the furnace 2 , the cyclone 3 and the circulating material recovery pipe 4 .

The rear flue 5 has a flow path through which the gas discharged from the cyclone 3 flows to the rear stage. The rear flue 5 has a superheater 10 for generating superheated steam and an economizer 12 for preheating boiler feed water as an exhaust heat recovery section for recovering the heat of the exhaust gas. The exhaust gas flowing through the rear flue 5 is cooled by heat exchange with steam and boiler feed water flowing through the superheater 10 and economizer 12 . It also has a steam drum 8 in which the boiler feedwater that has passed through the economizer 12 is stored, and the steam drum 8 is also connected to the furnace wall pipe 6 .

The economizer 12 transfers the heat of the exhaust gas to the boiler feed water to preheat the boiler feed water. Economizer 12 is connected to pump 7 by pipe 21 and to steam drum 8 by pipe 22 . Boiler feed water supplied from pump 7 via pipe 21 to economizer 12 and preheated by economizer 12 is fed via pipe 22 to steam drum 8 .

A downcomer pipe 8 a and a furnace wall pipe 6 are connected to the steam drum 8 . Boiler feed water in the steam drum 8 descends down the downcomer pipe 8a, is introduced into the furnace wall pipe 6 on the lower side of the furnace 2, and flows toward the steam drum 8. The boiler water supply in the furnace wall tube 6 is heated by the combustion heat generated in the furnace 2 and evaporated in the steam drum 8 to become steam.

A saturated steam pipe 8b is connected to the steam drum 8 for discharging the steam inside. The saturated steam pipe 8 b connects the steam drum 8 and the superheater 10 . The steam in the steam drum 8 is supplied to the superheater 10 via the saturated steam pipe 8b. The superheater 10 uses the heat of the exhaust gas to superheat steam to generate superheated steam. The superheated steam passes through the pipe 10a, is supplied to the turbine 100 outside the plant 1, and is used for power generation.

The pressure and temperature of the steam discharged from the turbine 100 are lower than the pressure and temperature of the steam discharged from the superheater 10. Although not particularly limited, the pressure of the steam supplied to the turbine 100 is about 10-17 MPa, and the temperature is about 530-570.degree. The pressure of the steam discharged from the turbine 100 is about 3-5 MPa, and the temperature is about 350-400.degree.

A condenser 102 is provided downstream of the turbine 100 . Steam discharged from the turbine 100 is supplied to the condenser 102 , condensed in the condenser 102 and returned to saturated water, and then supplied to the pump 7 . Turbine 100 is connected to a generator that converts kinetic energy obtained by rotation of turbine 100 into electrical energy.

The pump 7a supplies make-up water so as to keep the water level of the condenser 102 constant. FIG. 1 shows the make-up water flow rate u1 (an example of the measured value included in the “process data”) supplied by the pump 7a.

The process data according to the present embodiment is data relating to the operation of the plant 1, and can also be referred to as operation data. The process data may be, for example, data output by a sensor installed at a predetermined location in the plant 1. More specifically, at least one measured value such as the temperature, pressure and flow rate of the plant 1 may contain. The plant 1 includes at least one system. Here, the system refers to a predetermined part in the target facility, specifically the furnace (more specifically, the lower part of the furnace, the central part of the furnace, the upper part of the furnace, etc.), the outlet, the cyclone, the circulating material It may also include collection tubes, flue gas channels, heaters, back flues, and the like. The system may be arbitrarily set according to the design of the target facility. Each process data belongs to one of the systems constituting the plant 1 according to, for example, the installation position of the sensor that outputs the process data and the detection target. Moreover, each of the plurality of process data belonging to the same system corresponds to a specific order within the system defined according to the design of each system. The "(specific) order within the system" means not only the order of "upstream to downstream" set in the system, but also the order of "downstream to upstream" set in the system, or any other direction. including the order in

FIG. 1 shows the boiler feed water flow rate u2 supplied from the pump 7 to the economizer 12 (an example of the measured value included in the "process data"). Furthermore, FIG. 1 shows a boiler outlet steam flow rate u3 (an example of a measured value included in “process data”) supplied from the superheater 10 to the turbine 100, and saturated steam supplied from the steam drum 8 to the superheater 10 Flow rate u4 (an example of a measured value included in "process data") is shown. The make-up water flow rate u1 may be controlled so as to follow the saturated steam flow rate u4. Further, while monitoring both the boiler outlet steam flow rate u3 (or superheated steam flow rate) and the liquid level of the steam drum 8, the boiler feed water flow rate u2 may be controlled to follow the adjustment.

When a hole is formed in a pipe or the like that constitutes the plant 1, the make-up water flow rate u1 increases, or the flow rate difference between the boiler feed water flow rate u2 and the boiler outlet steam flow rate u3 increases. DCS (Distributed Control System) 20 receives process data of plant 1 such as makeup water flow rate u1, boiler feed water flow rate u2, boiler outlet steam flow rate u3, saturated steam flow rate u4, etc. The operation status including the operation rate of the turbine 100 is grasped, and the plant 1 is monitored for any abnormality.

Although the make-up water flow rate u1, the boiler feed water flow rate u2, the boiler outlet steam flow rate u3, and the saturated steam flow rate u4 have been exemplified as process data, the process data relating to the plant 1 may be other data. The process data relating to the plant 1 may be other data such as temperature and pressure, data calculated based on a plurality of process data, or uncalculated data obtained from sensors or the like. may

The process data acquisition unit 311 , for example, sequentially acquires process data from the DCS 20 during operation of the plant 1 and stores the acquired process data in the storage unit 33 .

Based on each process data acquired by the process data acquisition unit 311, the object data generation unit 312 generates object data that defines the display content/display mode of the object corresponding to each process data. As will be described later, the object based on the object data is displayed on the display device 32 by the display control unit 313 . Since the display content/display mode of the object is based on the corresponding process data, the operator can grasp the value, tendency, etc. of the process data corresponding to the object by visually recognizing the object. The display content/display mode of the object will be further described later.

The display control unit 313 causes the display device 32 to display each object based on each object data generated by the object data generation unit 312 . At this time, the display control unit 313 groups each object for each system of the plant 1 to which the corresponding process data belongs, and causes the display device 32 to display them. Here, "grouping for each system" may include forming a cohesive set with a specific part of the system as one unit. Arrangement of objects will be described further below.

The operation accepting unit 314 is an example of an accepting unit, and accepts any operation by the operator via the input unit 30e. The operation accepting unit 314 may accept selection of at least one of the plurality of objects displayed on the display device 32, for example. At this time, the display control unit 313 may cause the display device 32 to display the time-series graph of the process data corresponding to the object whose selection has been accepted. In addition, the display control unit 313 may switch display and non-display on the display device 32 of the time-series graph of the process data corresponding to the object whose selection has been accepted.

Various display screens displayed by the display device 32 will be described later.

The storage unit 33 stores various information. The storage unit 33 may store process data acquired by the process data acquisition unit 311, for example. Also, the storage unit 33 may store the object data generated by the object data generation unit 312 . The storage unit 33 may also store settings related to display contents and/or display modes of objects corresponding to process data, and settings related to display of time-series graphs of process data, which will be described later.

Each functional block of system 30 shown in FIG. 2 is realized by the physical configuration shown in FIG.

In this embodiment, the case where the system 30 is composed of one computer will be described, but the system 30 may be realized by combining a plurality of computers. For example, in addition to the display section 30f, a display constituting a different display section for displaying other information may be provided. Moreover, the system 30 may be configured by a tablet terminal. By configuring the system 30 with a tablet terminal, the system 30 can be carried around, and the system 30 can be used while patrolling the plant 1, for example. Moreover, the configuration shown in FIG. 3 is an example, and the system 30 may have configurations other than these, or may not have some of these configurations. Also, part of the configuration may be provided at a remote location. For example, the control unit 31 having the CPU 30a and the like may be provided at a remote location. In this case, the display device 32 having the display section 30f and the like may be configured to acquire, via the network, the control signal generated by the control section 31 provided at a remote location.

The CPU 30a is a computing unit that controls the execution of programs stored in the RAM 30b or ROM 30c and computes and processes data. The CPU 30a is an arithmetic unit that executes a program (monitoring program) for displaying a graph of process data of the plant 1 and explanatory text. The CPU 30a receives various data from the input section 30e and the communication section 30d, and displays the calculation results of the data on the display section 30f and stores them in the RAM 30b.

The RAM 30b is a rewritable part of the storage unit, and may be composed of a semiconductor storage element such as a DRAM or SRAM. The RAM 30 b may store data such as programs executed by the CPU 30 a and process data of the plant 1 . Note that these are examples, and the RAM 30b may store data other than these, or may not store some of them.

The ROM 30c is one of the storage units from which data can be read, and may be composed of, for example, a semiconductor storage element such as a flash memory, or an HDD. The ROM 30c may store, for example, a computer program for executing various processes shown in this embodiment and data that is not rewritten. The data that is not rewritten includes, for example, information about the plant 1, the specifications of the components of the plant 1, and the like. The ROM 30c may also store, for example, data such as the above-described process data, object data, settings related to the display content and/or display mode of objects, and settings related to the display of time-series graphs of process data.

The communication unit 30d is an interface that connects the system 30 to other devices. The communication unit 30d may be connected to a communication network such as the Internet.

The input unit 30e receives input of data according to operations by the operator, and may include, for example, a keyboard and a touch panel.

The display unit 30f has a screen that visually displays the calculation result by the CPU 30a, and may be configured by, for example, an LCD (Liquid Crystal Display). The display unit 30f may display a graph of process data and an explanation. Further, the display unit 30f may be provided so as to configure one screen by connecting a plurality of displays.

A computer program for executing various processes shown in the present embodiment may be stored in a computer-readable storage medium such as the ROM 30c and provided, or may be provided via a communication network connected by the communication unit 30d. may be provided. In the system 30, various operations included in the present embodiment are realized by the CPU 30a executing the monitoring program. It should be noted that these physical configurations are examples, and do not necessarily have to be independent configurations. For example, the system 30 may include an LSI (Large-Scale Integration) in which the CPU 30a and the RAM 30b or ROM 30c are integrated.

Next, with reference to FIG. 4, operation processing related to acquisition of process data and generation of object data of the system 30 according to the present embodiment will be described. In the operation processing, the process data of the plant 1 is acquired, and object data defining the display mode/display mode of the object corresponding to the process data is generated based on the process data. Note that the contents and order of the steps shown below are examples, and the operation process is not limited to this.

(S11) First, the process data acquisition unit 311 acquires the process data of the plant 1 from the DCS20. The process data may include, for example, at least one measured value output by a sensor installed in the plant 1 and time information when the at least one measured value was obtained. The timing at which the process data acquisition unit 311 acquires process data is not particularly limited, and may be arbitrary timing for each sensor installed in the plant 1 . The process data acquisition unit 311 causes the storage unit 33 to store the process data acquired from the DCS 20 .

(S12) Next, the object data generation unit 312 generates object data based on the acquired process data, and stores the generated object data in the storage unit 33. FIG.

The object may include, for example, information indicating the value of the corresponding process data, and more specifically, may include text indicating the value of the process data. The object may also include, for example, information indicating an increase/decrease trend of the value of the corresponding process data. The object data generation unit 312 calculates, for example, the trend of increase or decrease in the process data based on the process data obtained from the same sensor within the most recent predetermined period, and includes information indicating the trend of increase or decrease in the object data. may The information indicating the trend of increase/decrease may be, for example, text such as "Increase", "Decrease", and "Maintain", or an arrow pointing in the direction corresponding to the increase/decrease. The object may also include information indicating the judgment result (normal, abnormal, caution, etc.) for the value of the process data output by the predetermined judging unit.

For example, the display mode of the object may be defined according to the comparison between the value of the corresponding process data and the reference value set for the corresponding process data. The reference value may be arbitrarily set according to the type of process data (that is, the type and installation position of the sensor), etc. For example, it may be a desired normal value for the process data. The object data generation unit 312 calculates the difference between the process data and the reference value, the ratio of the process data to the reference value, and the like, and then generates information that defines the display mode according to the magnitude of the difference, ratio, etc. May be included in object data. The display mode is not particularly limited as long as it is a display mode of the object, and may be, for example, the color or gradation of the object, or may be the shape, size, or the like of the object.

The operation processing of steps S11 and S12 described above is repeated until a predetermined termination condition such as the termination of the operation of the plant 1 is satisfied.

Next, with reference to FIG. 5, operation processing related to object display in the system 30 according to the present embodiment will be described. In the operation processing, an object corresponding to the process data is displayed on the display device 32 based on the object data generated based on the process data of the plant 1 . Note that the contents and order of the steps shown below are examples, and the operation process is not limited to this.

(S21) First, the display control unit 313 determines whether or not a predetermined update cycle regarding object display has arrived. The length of the update cycle is not particularly limited and may be set arbitrarily. If it is determined that the update cycle has arrived (S21; Yes), the process proceeds to step S11. On the other hand, when it is determined that the update period has not arrived (S21; No), the step S10 is executed again.

(S22) When it is determined that the update cycle has arrived, the display control unit 313 generates object data corresponding to each process data of the plant 1 based on the object data generated by the object data generation unit 312 in step S12 described above. (see FIGS. 6 and 7) is displayed on the display device 32. FIG. Thereafter, steps S21 and S22 described above are repeatedly executed until a predetermined termination condition is satisfied. As a result, the display device 32 displays changes over time in the process data of the plant 1 .

FIG. 6 is a diagram showing an example of a screen displayed on the display device 32 according to this embodiment. FIG. 6 shows a screen DP1 as an example of a screen displayed on the display device 32. As shown in FIG. The screen DP1 is displayed on the display device 32 based on display data generated by the display control unit 313 of the system 30, for example.

A plurality of objects corresponding to each process data included in a plurality of process data may be grouped and displayed on the screen DP1 for each system of the plant 1 to which each process data belongs. In the example shown in FIG. 6, a chart 100 including a plurality of substantially rectangular objects 101 corresponding to each process data of the plant 1 is displayed on the screen DP1. As described above with reference to FIG. 5, the display control unit 313 updates the display content of the display device 32 according to the arrival of the predetermined update cycle. Therefore, for example, during operation of the plant 1, the contents of each object 101 included in the chart 100 shown in FIG. 6 may change over time based on the latest object data generated by the object data generation unit 312. .

As shown in FIG. 6, the values of the corresponding process data are displayed in the object 101. Note that the object 101 may contain other arbitrary information, such as information indicating an increase/decrease tendency of the process data value, judgment results (normal, abnormal, caution, etc.) for the process data value, and the like. may be included.

In FIG. 6, the shape of the object 101 is substantially rectangular. However, the shape of the object 101 is not limited to a substantially rectangular shape, and may be any shape such as a substantially polygonal shape, a substantially circular shape, or an irregular shape. Also, in FIG. 6, the sizes of the objects 101 are all substantially the same, but each object 101 may have a different size. The inside of each object 101 shown in FIG. 6 is hatched with a predetermined density.

Arbitrary display modes including the shape, size, color, gradation, etc. of the object 101 are defined by colors according to comparison between the value of the corresponding process data and the reference value set for the process data. may be Specifically, for example, an arbitrary display mode including the shape, size, color, gradation, etc. of the object 101 is defined by the value of the corresponding process data and the reference value set for the process data. The color may be defined according to the difference, the ratio of the process data to the reference value, or the like. Here, the reference value may be arbitrarily set according to the type of process data (that is, the type and installation position of the sensor). good too. For example, in the example shown in FIG. 6, when the density of oblique lines in the object 101 represents the color, the larger the difference or ratio, the longer the wavelength of the object 101 (more warm). The color of the object 101 corresponds to a color with a shorter wavelength (colder color) as the value of the difference or ratio is smaller. Note that the relationship between the value of the difference or ratio and the color of the object 101 may be reversed. Similarly, for example, in the example shown in FIG. 6, when the density of oblique lines in the object 101 represents the gradation, the larger the value of the difference or ratio, the brighter the gradation of the object 101. The smaller the value such as the ratio, the darker the gradation of the object 101 . It should be noted that the relationship between the value of the difference or ratio and the brightness of the gradation may be reversed.

As described above, the display mode of the object 101 can be confirmed by defining the display mode of the object 101 according to the comparison between the value of the corresponding process data and the reference value set for the process data. , it is possible to easily grasp the degree of divergence from the reference value of the process data.

In the chart 100, each object 101 is grouped for each system of the plant 1 and arranged. FIG. 6 shows an example in which the plant 1 includes systems 1 to 10 . Note that this is an example, and the number of systems included in the plant 1 is not particularly limited. Specifically, the objects 101 belonging to the system n (n is any integer from 1 to 10) are arranged adjacent to each other in a horizontal row on the n-th row in the chart 100 . In FIG. 6, the number of objects 101 belonging to the system 1 is 12, the number of objects 101 belonging to the system 2 is 6, etc., but these are only examples, and the objects 101 belonging to each system is not particularly limited. In this way, by grouping and arranging the objects 101 for each system, it is possible to efficiently check the process data in a manner associated with the system.

In this embodiment, the objects are "grouped and arranged", as shown in FIG. Other arrangements may be used as long as they can be grasped. Examples of such "grouped and arranged" modes include a mode in which objects belonging to the same system are arranged in a vertical line, a mode in which objects belonging to the same system are arranged diagonally, and a mode in which objects belonging to the same system are arranged diagonally. may include an aspect in which objects belonging to are arranged in a curved line. Objects belonging to the same system and objects belonging to different systems may not be adjacent to each other, and may be separated by an arbitrary distance.

In the chart 100 shown in FIG. 6, the objects 101 belonging to each system are arranged in an order according to the order of the corresponding process data within the system. Specifically, for example, the objects 101 included in each system are arranged along the order of the corresponding process data within the system from left to right. In other words, the object 101 corresponding to the process data earlier in the lineage (upstream) is placed further to the left, and the object 101 corresponding to the process data later in the lineage (downstream). 101 is placed further to the right. This makes it possible to grasp a plurality of process data together with the order in each system. Note that the order of arranging the objects 101 belonging to each system is not limited to the order of the corresponding process data within the system, and may be any order. The order may be according to the comparison between the value and the reference value.

FIG. 7 is a diagram showing an example of a screen displayed on the display device 32 according to this embodiment. FIG. 7 shows a screen DP2 as an example of a screen displayed on the display device 32. As shown in FIG. The screen DP2 is displayed on the display device 32 based on display data generated by the display control unit 313 of the system 30, for example.

The screen DP2 may include a time-series graph of process data corresponding to an object selected from a plurality of objects in addition to the plurality of objects corresponding to each process data described above. In the example shown in FIG. 7, a chart 100 including a plurality of objects 101 is displayed on the screen DP3, and a time-series graph 200 is included below the chart 100. FIG. A time-series graph 200 is a time-series graph of process data corresponding to an object 101 selected from multiple objects 101 included in the chart 100 . In the time-series graph 200, the horizontal axis indicates time information, and the vertical axis indicates values of process data.

When the operator performs an operation of selecting any at least one object 101 from among the plurality of objects 101 included in the chart 100 via the input unit 30e, the operation receiving unit 314 performs the selection operation of the object 101. accept. Then, the display control unit 313 acquires the process data corresponding to the selected object 101 from the storage unit 33 and displays the time-series graph 200 of the process data.

In the example shown in FIG. 7, the chart 100 shows an example in which two objects, an object 101P belonging to system 5 and an object 101Q belonging to system 7, are selected. The time-series graph 200 shows a time-series graph 201P of process data P corresponding to the object 101P and a time-series graph 201Q of process data Q corresponding to the object 101Q. In the time-series graph 200, the vertical axis on the left side corresponds to the process data P, and the vertical axis on the right side corresponds to the process data Q. FIG.

Note that the operation reception unit 314 selects an object 101 (

objects

101P and 101Q in the example of FIG. 7) whose corresponding process data is already displayed in the time-series graph 200 among the plurality of objects 101 included in the chart 100. A selection may be accepted. Then, the display control unit 313 may prevent the time-series graph of the process data corresponding to the selected object 101 from being displayed from the time-series graph 200 in response to acceptance of the selection. That is, the display control unit 313 may switch display and non-display of the time-series graph of the process data corresponding to the selected object according to the selection by the operation reception unit 314 . As a result, the operator can selectively display desired process data in the time-series graph 200 by arbitrarily selecting the object 101 included in the chart 100 .

The aspects of implementation described through the above embodiments can be appropriately combined, modified, or improved according to the application, and the present invention is not limited to the description of the above embodiments. It is clear from the description of the scope of claims that such combinations, modifications, or improvements can also be included in the technical scope of the present invention.
