Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work suspension plan preparation support system for supporting the preparation of a work suspension plan for stopping each facility for inspection and expansion of power system facilities, and a recording medium storing the program. .

[0002]

2. Description of the Related Art In power system equipment, it is necessary to temporarily stop the operation of the equipment when performing inspection, expansion, and the like. Moreover, it is not preferable to stop these facilities individually each time it is necessary from the viewpoint of stable power supply. Therefore, the work stop plan issued from each request source has been adjusted. I have.

[0003] These stop plans are adjusted at a general control center, a central power supply command center, or the like. In this case, transmission and negotiation of the plan data are performed by telephone or facsimile between a large number of request sources for issuing the work stop plan and the general control center and the central power supply dispatching office that coordinate these plans.

[0004] Alternatively, data collected from a large number of requesters is collectively collected in a host computer via a network constructed with a public line or a LAN, and then the host computer performs stop plan adjustment processing. Is returned to the requesting source via a network.

[0005]

However, the conventional method has the following problems. (1) Communication and negotiation by telephone, FAX, etc. are complicated. (2) Computers need to be connected during a network session, such as message exchange. (3) Therefore, if the network throughput is low or the network is congested, it takes time to process.

(4) Similarly, the terminal that has issued the processing request cannot be shut down until the processing that has issued the processing request ends. (5) In general, the method of coordinating work between various locations is that once the requirements from all locations are listed and aligned,
For example, if a request change occurs in one location, to determine whether it can be changed, import all the information of all locations and recheck. It took time and effort to process it.

[0007] (6) In determining the stop plan, information on system equipment, supply and demand information, information outside the scope of its own control, for example, information on the weather system, and the results of the determination of the stop plan, etc. For example, it is necessary to notify a construction company or the like in a timely manner. In particular, when a request change occurs at one place as described in (5) above, or when the system status changes due to sudden construction, etc., or a sudden change in weather information, etc., it is timely linked. However, it is difficult to follow these situations in a timely manner.

(7) It is reasonable to have a “database” in a place where an “information processing mechanism” exists. Therefore, data tends to concentrate on a specific host computer, Even during the processing, the function of the host computer is occupied during that time, so the cost performance is not good.

FIG. 8 is a block diagram showing an embodiment of a system for supporting a work stoppage plan by an agent according to [claim 5] of the present invention. In FIG. 8, the same portions or the same functional portions as those in FIG.

In this embodiment, notification agents are registered in the planning request source, the integrated control station, the central power supply dispatching station, and the computer of the demand forecasting system, respectively, and these notification agents are distributed and managed in each location. At the timing when the data in the database is changed, the notification agent of the other department is notified of the change of the data.

Specifically, the notification agent of the demand forecasting system manages the demand and supply data (generator output value, load value,
It monitors the time when the target period changes, and if a change occurs, it has the address of the location related to the supply and demand data and a notification program, etc. , ..., General control station 1, ...,
Walk around the planning request n).

Then, the notification agent of the central power supply commanding station,..., The notification agent of the integrated control station 1,. In the figure, when the user first visits the central power supply dispatching center, his or her own coordinating agent is duplicated at the central power supply dispatching center.

The notification agent at the central power supply dispatching station,.
The notification agent of the integrated control station 1,..., The notification agent of the planning request source n updates the supply and demand data managed in its own department with the latest information notified from the notification agent of the demand forecasting system.

Here, it is assumed that the renewal of the supply and demand data requires a readjustment operation of the stop plan in each department. Specifically, it is assumed that readjustment work is required at the central power supply command center. In this case, the coordinating agent of the demand forecasting system in the central dispatching center is transmitted with request data for readjustment of the shutdown plan from the coordinating agent of the central dispatching center via inter-process communication.

The coordinating agent of the demand forecasting system carries out coordinating work with the coordinating agents of the respective departments by inter-process communication while walking on the network with the request data, and finally returns to the original central power supply command center. Then, the result of the adjustment is transmitted to the adjustment agent of the central power supply dispatching station by inter-process communication.

When walking on the network, not only make a round of the relevant departments, but also move back and forth between the departments as necessary. If it is not necessary to adjust the stop plan by updating the supply and demand data at the central dispatching center, the coordinating agent of the demand forecasting system in the central dispatching center walks over the network and goes to the next general control station 1 in the figure. From the coordinating agent of the integrated control station 1, the necessity of readjustment of the stop plan by updating the supply and demand data in the integrated control station 1 is communicated by inter-process communication.

If necessary, the request data for adjustment is transmitted by inter-process communication.

According to this embodiment, it is possible to automate the notification of the change in the information, and when the stop plan needs to be readjusted according to the notified result,
The adjustment work can be automated.

FIG. 9 is a block diagram showing an embodiment of a system for supporting a work stoppage plan by an agent according to [claim 6]. In FIG. 9, the same portions or the same functional portions as those in FIG.

In the present embodiment, the coordinating agent is registered in the computer of the planning request source and the computer of the general control office, and the coordinating agent coordinates the coordination agent with the coordinating agent of another department at the timing of creating the work stoppage plan. Perform

More specifically, the coordinating agent of the plan request source 1 requests the data (scheduled work date, stop equipment location, work adjustment date data to be updated while walking) inputted by the plan request source 1, With the address, the adjustment process, etc., it walks over the relevant places on the network (plan request source 2,..., Plan request source n).

At this time, the coordination between the coordinating agents of the plan request source 2,..., And the coordinating agent of the plan request source n is adjusted. If the work dates and times are different for the stopped facility, the work dates and times are integrated), and the process returns to the original plan request source 1 with the adjustment result obtained therefrom. When walking around on a network, not only go around each department, but also go back and forth between departments as needed for coordination.

Here, it is assumed that the coordinating agent of the result request source 1 has failed to adjust and settle with the coordinating agent of another plan request source while walking across the network as described above. If the coordination between coordinating agents results in a situation in which they cannot be transferred, the coordinating agent uses the permission authority rank information that was set in advance when each coordinating agent was registered at each location. Settle at the next higher level.

Specifically, it is assumed that the agents of the plan request source 1 and the agents of the plan request source 2 have fallen into a state in which they cannot be transferred as a result of the adjustment at the plan request source 2 (the plan request source 1 and the plan request source 2). 2 has the same permission authority rank α). Then, the coordinating agent of the planning request source 1 having this fallen information walks over the network to the general control office where the coordinating agent of the higher β rank has one permission authority rank, and communicates with the coordinating agents of the general control office. Coordination is performed by inter-process communication.

Then, with the adjusted result, the coordinating agent of the plan request source 1 returns to the plan request source 2 on the network, and sends the adjusted result to the coordinating agent of the plan request source 2 by inter-process communication. After communication, in order to coordinate the plan with other coordinating agents,
Walks over the network again, and finally returns to the original plan requester.

According to the present embodiment, when the coordinating agents of the plan requesters do not make coordination and settlement, the coordinating agent of the higher-level integrated control center makes coordination and settlement, so that advanced coordination work can be automated.

FIG. 10 is a block diagram showing an embodiment of an agent-based work stoppage planning support system according to [claim 7] of the present invention. In FIG. 10, the same portions or the same functional portions as those in FIG.

Specifically, first, the coordinating agent is registered at the planning request source 1, and after having been walked over the network,
This coordinating agent finishes the work and the original plan request source 1
If the terminal of the plan request source 1 is shut down before returning to the above, the coordinating agent registered at the plan request source 1 walking on the network will receive a plan request from the system monitoring unit in its own agent. It detects that the former terminal is shut down.

The coordinating agent of the plan request source 1 which has detected that the terminal of the plan request source 1 is shut down, for example, at the plan request source 2 before returning to the plan request source 1,
It waits until the terminal of the plan request source 1 starts up. Whether or not the terminal of the plan request source 1 has started up is regularly monitored by the system monitoring unit in this agent.

During the standby, the standby state is set as the program state in the coordinating agent of the plan request source. For this reason, even if the terminal of the plan request source 1 is shut down, there is no problem in the plan adjustment. Further, if there is another agent registered at another place and trying to visit the own terminal, even if the own terminal is shut down, the other agent waits at three places in the figure, so that there is no problem.

Specifically, in the case of 3 in the figure, the coordinating agent of the plan request source 5 is changed from the plan request source 3 to the plan request source 1
Then, when trying to walk on the network, the system monitoring unit in the own agent detects that the terminal of the plan request source 1 is shut down.

The coordinating agent of the plan request source 5, which has detected that the terminal of the plan request source 1 has been shut down, waits until the terminal of the plan request source 1 starts up at the plan request source 3, and the system in this agent The monitoring unit periodically monitors whether the terminal of the plan request source 1 has started up. According to the present embodiment, it is possible to shut down the terminal requesting the plan even during the adjustment of the plan.

FIG. 11 is a block diagram showing an embodiment of an agent-based work suspension plan support system according to [claim 8] of the present invention. In FIG. 11, the same portions or the same functional portions as those in FIG. 10 are denoted by the same reference numerals and description thereof will be omitted.

At the central power supply dispatching station, the power flow of the power system is calculated based on the facility data and the supply and demand data owned by each planning request source, the general control station, and the central power dispatching station, and requested. The tidal current conditions are checked to make sure that the equipment shutdown plan does not hinder system operation.

Specifically, the power flow calculation agent registered at the central power supply dispatch office walks over the network,
The facility data and supply / demand data managed at each location are obtained from each location, and the process returns to the original central power supply command center to execute the power flow calculation process.

At this time, it is assumed that the computer processing load is high because another agent is performing a process at the central power supply command center. This load situation is detected from time to time by a performance monitor of a computer at each location, and when a certain criterion is exceeded, the agent requesting the process is notified of the situation where the load is currently high.

The power flow calculation agent having received the notification walks over the network and issues a processing request at the general control station 2 at another location. Since the performance monitor is set at each location, if a high load is notified even at the location where the performance monitor is moved, the performance monitor is moved to another location on the network and a processing request is made.

In this way, the agent performs the processing while avoiding the place where the computer processing load is high. After the processing is completed, it moves over the network and returns to the original place. When a high load message is received at all locations, processing is performed after returning to the original location.

According to the present embodiment, the agent walks over the network to a place where the computer processing load is low, avoiding a place where the computer processing load is high, and performs the processing there. Can be automatically distributed.

FIG. 12 is a block diagram showing an embodiment of a system for supporting a work stoppage plan by an agent according to claim 9 of the present invention. In FIG. 12, the same portions or the same functional portions as those in FIG. 10 are denoted by the same reference numerals, and description thereof will be omitted.

Specifically, the power flow calculation agent registered at the central power supply dispatch office walks over the network,
It is assumed that facility data and supply / demand data managed at each location are obtained from each location, and that the user returns to the original central power supply dispatching station and intends to execute power flow calculation processing.

In this case, it is assumed that the plan request source 2 has shut down the terminal, and the facility data and supply / demand data of the plan request source 2 cannot be obtained immediately. In this case, the tide calculation agent sets a revisit flag in the address area on the network of the plan request source 2 in the address setting unit of the agent itself.

The tidal calculation agent visits the next plan request source 1 by putting off the place where the revisit flag is set,
After the acquisition of the necessary data at the plan request source 1 is completed, the plan request source 2 corresponding to the address for which the revisit flag is set is revisited. When a plurality of revisit flags are set, revisits are started in an order starting from the oldest time at which the flag was set. In this way, the power flow calculation agent, which has completed the crossing of all the points, finally returns to the central power supply command center.

According to the present embodiment, when an agent walks on a network, if there is a terminal that is shut down, the terminal is postponed, and the agent walks from another location first, so that the agent can easily walk around the network. , The priority of visiting each location can be automatically determined.

FIG. 13 is a block diagram of an embodiment of a recording medium according to claim 10 of the present invention. More specifically, the program according to claim 1 exists on a main memory in the computer in the figure and on an auxiliary storage device connected to the computer by a general-purpose SCSI cable or the like, that is, inspection of power system equipment.
