Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation monitoring apparatus for a power plant, in which the operation from the start of the power plant to the completion of the start is divided into a plurality of operation stages to operate each operation item. Regarding

[0002]

2. Description of the Related Art Generally, operation of a power plant from start-up to completion of start-up is performed as follows. First, at the time of starting the power plant, the boiler water supply system is cleaned up and the boiler water supply pump that is an auxiliary machine is started before starting the boiler, which is the main engine. And
When the boiler is started, for example, the burner is ignited, the temperature of the steam is raised and boosted, and the main steam satisfies the conditions for ventilation of the turbine, the main steam is vented to the turbine to start the turbine. When the turbine starts up to the rated speed, the generator is started and the generator is inserted in the electric power system in parallel to complete the start of the power plant.

The operation operation from the start-up to the completion of the start-up of such a power plant is automated and is executed by a command from a computer. In this case, the operator needs to know how far the driving operation by the computer is progressing. Therefore, conventionally, as shown in FIG. 29, the progress table of the driving operation is displayed on the CRT display device.

That is, the operation from the start of the power plant to the completion of the start is performed by a plurality of operation stages, for example, start,
The display was divided into ignition, ventilation, parallel entry to completion of startup. Each of these operation stages includes operation items required from start-up of the power generation plant to completion of start-up, such as the above-described burner ignition operation and steam temperature raising / pressurizing operation.

Conventionally, for the driving stage in which the operation items included in each driving stage have been completed, the operation stage operation is displayed as being completed.

[0006]

However, in such a conventional device, since the actual progress of driving is simply displayed, the operation currently in progress is delayed from the planned driving schedule. Whether it is moving or not, it is not possible to judge from this progress display alone. Further, only the driving stage is displayed, and it is difficult to judge the degree of progress of each operation item included in the driving stage. Therefore, even if it is later determined that the driving operation is delayed, the planned driving schedule may not be kept. As described above, in the conventional case, it is largely determined by the operator, and it is difficult to accurately determine the degree of progress of driving.

Therefore, it is an object of the present invention to provide an operation monitoring apparatus for a power plant that can easily inform an operator whether or not the operation of the power plant is proceeding according to a scheduled operation schedule. .

[0008]

The operation monitoring apparatus for a power plant according to the present invention uses the scheduled operation start time of each operation item required to be operated from the start of the power plant to the completion of the start of the process from the power plant. An operation schedule calculation means for calculating the operation schedule based on the signal, and the operation start scheduled time of the first operation item in the predetermined operation stage among the operation disclosure scheduled times of the respective operation items calculated here, the operation stage start scheduled time As a calculation time extraction means, a scheduled progress display means for displaying the operation stage start scheduled time extracted by the calculation time extraction means on the display as a schedule progress table, and the operation start record of the first operation item in the operation stage The actual time collection means that inputs the time from the power plant as the actual operating stage start time, and the actual time collector And a performance progression display means in which the display device the collected operational stage start record time as actual progress table.

Further, the scheduled operation stage start time extracted by the calculation time extraction means and the actual operation stage start time collected by the actual time collection means are compared for each operation stage, and when a predetermined deviation is exceeded, an alarm is issued. It is provided with an alarm output means for issuing.

Furthermore, the request input means for the operator to select each operation stage in the schedule progress table and the actual progress table, and the operation stage start schedule in the schedule progress table of the operation stage selected by this request input means Display conversion means for displaying the scheduled progress table and the actual progress table by matching the starting points of the time and the actual operation stage disclosure actual time in the actual progress table.

On the other hand, the operation stage judgment means for judging to which operation stage the operation of the power plant progresses, and the operation of the operation item in the operation stage judged by the operation stage judgment means is completed. It is provided with a driving operation stage situation determination means for determining whether or not it is present and displaying the determination result on a display.

[0012]

With this configuration, as the operation schedule of the power plant, the scheduled operation stage start time is displayed on the display as a schedule progress table, and the actual operation stage start time is also displayed on the display together as the actual progress table.
Therefore, the operator can easily determine whether the operation progress of the power plant is behind or ahead of schedule.

Also, if the schedule is significantly delayed or advanced, a warning is issued. Therefore, the operator's attention is called.

Further, according to the operator's request, the starting point can be displayed at the operation stage start time of each of the scheduled progress table and the actual result progress table of the operation schedule of the power plant, so that the operator can display more. Judgment becomes easy.

On the other hand, according to the request of the operator, the progress degree of each operation item included in the operation stage in which the operation is progressing can be displayed, so that the operation progress degree of the power plant can be determined in detail.

It can be notified by 3. Therefore, when a large deviation occurs between the scheduled time and the actual time, the operator can be notified through the alarm window.

FIG. 19 is a block diagram showing the third embodiment of the present invention. This third embodiment is similar to the second embodiment shown in FIG.
When the operator selects each operation stage in the schedule progress table and the actual progress table, the operation stage start scheduled time in the schedule progress table of the selected operation stage and the operation stage in the actual progress table It has a function of displaying the schedule progress table and the actual progress table by matching the starting point with the start actual time. The details will be described below.

That is, the request input means 30 inputs the display type information r from the request selection screen displayed on the display 13 and outputs it as the type information s. Request input judging means 31
As shown in FIG. 20, if the type information s is “← ▲”, the display selection = 1, and if “▲ →”, the display selection = 2, and the first display conversion unit 32 is notified. If the type information s is "enlarged", the display selection is set to 3 and the second display conversion means is notified.

The first display conversion means 32 takes out the scheduled calculation time calculated by the operation schedule calculation means 3 as shown in FIG. 21, and calculates the relative time from the start of activation for each event, which is designated as Yi. . Also, the actual time storage means 10
The actual time of each event saved in is extracted, and the relative time from the actual start time of each event is calculated and set as Ai. Yi: Scheduled time of each event-Scheduled start time Ai: Actual time of each event-Actual start time

If the display request t1 = 1 (← ▲), the display start stage is moved to the previous stage, and the display request t
If 1 = 2 (▲ →), the displayed starting stage is moved to the next stage, and the relative time from the start of the starting stage is calculated and set as D1 and D2. D1: Schedule start point start time-start start time D2: Actual start stage start time-start start time

Next, the progress display position of each stage from the starting stage is calculated. Yi: Yi-D1 (scheduled side) Ai: Ai-D2 (actual side)

CRT display information is created from the planned and actual stage progress display positions with the starting stage as the starting point, and the third output means 34 is notified as display information 1 (u1).

As shown in FIG. 22, the second display conversion means 33 is activated by the notification of the display request t2, and the operation schedule calculation means 3 is provided with the respective operation times and required times of the in-stage operation items for the current starting stage. CRT which retrieves from the scheduled data calculated by the above and the actual data stored by the actual time storage means 10 and displays the expanded progress of the planned and actual CRT.
Display information is created and notified to the third output means 34 as display information 2 (u2).

The third output means 34 displays the display information 1 (u1) created by the second display conversion means 32 or the display information 2 (u2) created by the second display conversion means 33 on the display. It is converted into performance progress display information n to 13 and output to the display unit 13.

With the above configuration, in the state where the progress display screen shown in FIG. 23A is displayed and the starting stage is starting to start, "▲ →" is displayed in order to display the ventilation stage as the starting point. When the request is made twice, the request input means 30 inputs the request data and notifies the request input judgment means 31. Since the request is “▲ →”, the request input judging means 31 notifies the first display converting means 32 that the display selection = 2. The first display conversion means 32 takes out the scheduled time (start, ignition, ventilation, parallel, start completion) calculated by the operation schedule calculation means 3 and calculates the relative time from the start of the start. Y1 = Planning start-Planning start = 0 = 0 Y2 = Planning start-Planning start Y3 = Ventilation starting plan-Planning start Y4 = Parallel starting plan-Planning start Y5 = Planning completion-Planning start

Further, the actual time (starting, ignition, ventilation, parallel, starting completion) stored in the actual time storing means 10 is taken out and the relative time from the start of starting is calculated. A1 = Starting start record-Starting record = 0 A2 = Ignition start record-Starting record A3 = Ventilation start record-Starting record A4 = Parallel starting record-Starting record A5 = Starting completion record-Starting record

Next, since the display request t1 = 2 (▲ →), the starting stage of display is set to the next stage (because the starting stage is ventilated because it is requested twice), and the starting stage (venting is started) ) To calculate the relative time. D1 = Scheduled ventilation start-Scheduled startup start = Y3
-Y1 D2 = Aeration start record-Startup record = A3
-A1

Next, the progress display position of each stage from the starting stage (ventilation) is calculated. Schedule side Y1 = Y1-D1 Y2 = Y2-D1 Y3 = Y3-D1 = 0 (starting stage) Y4 = Y4-D1 Y5 = Y5-D1 actual side A1 = A1-D2A3 = D2-A2 = A2-D2 = 0 (starting stage) A4 = A4-D2 A5 = A5-D2

Progress display information is created from the obtained progress display position of each stage, and is notified to the third output means 34. Third
The output means 34 creates the CRT display data from the progress display information and outputs it to the display 13 as shown in FIG. Further, when "▲ →" is requested twice, the same operation as above is repeated and the starting stage is completed, and the automation progress display screen displayed on the display 13 starts from the completion of starting as shown in (e) of FIG. Is displayed.

When "enlarge" is requested on the progress display screen shown in FIG. 23 (d), the request input means 30 inputs the request data and notifies the request input judging means 31. Since the request is “enlargement”, the request input determination means 31 sets display selection = 3 and notifies the second display conversion means 33. Second
Since the position of the starting point stage is “ventilation” by performing the determination shown in FIG. 22, the display conversion means 33 of FIG. 22 shows the scheduled time data calculated by the operation schedule calculation means 3 and the actual results saved by the actual time saving means 10. Each operation time and required time in the ventilation stage are taken out from the time data to create the advancing stage enlarged display information, which is notified to the third output means 34. As shown in FIG. 24, the third output means 34 creates CRT display data from the advancing stage enlarged display information and outputs it to the display unit 13.

In the third embodiment, the scheduled data and the actual data can be compared with each other starting from an arbitrary stage of progress display, so that the advance / delay of other stages can be easily determined. In addition, by enlarging and displaying each stage, it is possible to easily judge the advance or delay of each operation item in the stage.

FIG. 25 is a block diagram showing the fourth embodiment of the present invention. The fourth embodiment differs from the third embodiment in determining to which operation stage the operation of the power plant progresses, and whether or not the operation of the operation item in the operation stage is completed. The judgment result of 1 is displayed on the display 13. The third input means 40 inputs the plant accessory state quantity v from the power plant 1, and determines the plant accessory state quantity x as the operation stage determination means 4
Output to 1. When the plant accessory state quantity x is input, the operation stage determination means 41 performs stage determination, and extracts the operation item of the stage to which the plant accessory state quantity x belongs, the operation time of each item, and the required time of the stage.

FIG. 26 shows the processing contents of the driving stage judging means 41. The operation stage determination means 41 divides the plant operation into four stages of activation, ignition, ventilation, and parallel, and determines which stage out of the four plant accessory state quantities x to which the input belongs. Here, a case where it is determined that the plant accessory state quantity x belongs to the ventilation stage will be described below.

When it is determined that the plant accessory state quantity x belongs to the ventilation stage, the operating stage determination means 41 determines the operation items (ventilation, love check, speed up 1, low speed heat soak, speed up 2) in the ventilation stage. , High-speed heat soak, parallel preparation) and the operation time of each operation item and the required time on the aeration stage. When the take-out is completed, the driving stage judging means 41 creates data for the enlarged progress table in the ventilation stage and outputs it as the driving stage information y to the driving stage internal situation judging means 42. When the operation stage information y is input, the in-operation stage situation determination means 42 determines the end of the operation item.

FIG. 27 shows the operating stage in-state situation judging means 42.
The processing content of is shown. When the driving stage information y is input to the driving stage information judging means 42, the driving stage information y
Is determined to belong to the ventilation stage, and whether each operation item on the ventilation stage is finished or not finished is determined, and the operation required time of the end item is accumulated and the operation required of the unfinished item is required. Accumulate time. Upon completion of the above calculation, the in-driving stage situation determining means 42 creates display data for the above calculation result and outputs it as in-stage incomplete / completion notice z to the in-driving stage end determining means 43. Upon receiving the in-stage incompletion / completion notice z, the operation stage end determination means 43 exchanges data so that it can be displayed on the display device 13, and outputs the display device display information h to the display device 13. When the display device 13 receives the display device display information h, the display device 13 outputs it as an in-stage end item display.

FIG. 28 shows an example of the end item display within the stage. In the fourth embodiment, the driving stage judging means 41 judges the stage of the operation item and prepares the enlarged progress display data, and the driving stage internal condition judging means 4
The end operation item is displayed on the bar graph by determining the end of the operation item and time integration of the end operation item and the unfinished operation item according to 2. Therefore, by displaying the end or non-end of the operation item on the bar graph, it is possible to easily grasp the progress of the operation in each stage.
