Submit a report.

The generated accident report includes audio data generated by a well-known voice synthesis device and an accident report (also referred to as an accident report or first report) including predetermined report items.

Furthermore, the content of an accident report consisting of audio data differs depending on the technical level of the person in charge at the destination. In other words, the reporting destinations include technical departments involved in the operation and management of power systems and non-technical departments other than the technical department (for example, public relations), and when creating an accident report for the non-technical departments, Instead of technical terms used in power system operation and management, reports are created using general terminology that can be understood by personnel in non-technical departments.

The power system accident reporting system 1 transmits the created accident report to the determined report destination. Figure 1 shows that the destination of an accident report varies depending on the type of power system accident. The power system accident reporting system 1 communicates with a central power dispatch center 3, a main power supply control center 4, a control center 5 related to power system accidents, and an operation control center 6 via the power company's operation control network NW. , a substation section 7, a power transmission section 8, a hydropower section 9, a civil engineering section 10, and a public relations section 11.

The substation section 7 performs maintenance and management of substations. Power Transmission Section 8 maintains and manages power transmission lines, steel towers, underground power transmission equipment, etc. Furthermore, the power transmission lines are installed across the jurisdictional areas of numerous business establishments. Therefore, when a power transmission line accident occurs, an accident report is sent to the power transmission divisions 8 of all the offices whose facilities are in charge of the relevant power transmission line. The Hydroelectricity Section 9 is a department that maintains and manages generators at hydroelectric power plants. For power line and substation accidents, an accident report is sent if the accident affects a hydropower plant. The civil engineering section 10 is a department that maintains and manages civil engineering equipment such as dams of hydroelectric power plants and rivers flowing into dams, and an accident report is sent when an accident affects civil engineering equipment.

The public relations department 11 is a department that disseminates information about the activities and products of the electric power company, and is installed, for example, at the head office of the electric power company. The public information 11 distributes information regarding power system accidents to power consumers and the like.

FIG. 2 is a functional block diagram showing a schematic configuration of the power system accident reporting system 1. As shown in FIG. The power system accident reporting system 1 mainly includes an input section 14, a display section 15, a storage section 16, a memory 17, a communication section 18, a main task 19, and a central processing section 20 that controls these.

The power system accident reporting system 1 determines the control program (operation system) for the entire device, the report destination and report items for the accident report, creates an accident report, and reports the created accident report on a personal computer, for example. An application (power system accident reporting program 161) that performs various processes for transmission to the destination is installed and configured.

The input unit 14 is an interface that has a function of inputting information to the power system accident reporting system 1 in response to instructions from a user, and is configured by, for example, a keyboard and a mouse.

The display unit 15 has functions such as displaying information input through the input unit 14 and displaying processing results of the power system accident reporting system 1, and is configured by, for example, a liquid crystal display.

The storage unit 16 is a storage area/storage device having a function of storing various information, programs, data, etc., and is configured by, for example, a hard disk. The storage unit 16 stores a control program for the entire power system accident reporting system 1 and a power system accident reporting program 161, as well as an equipment information database (hereinafter also referred to as DB) 162, an accident information database 163, and a performance database. 164, a report destination determination model 165, an accident report creation model 166, and the like are stored.

Although not shown in detail, the storage unit 16 stores a report destination database in which the telephone number, fax number, email address, etc. of each report destination to which the accident report is sent is stored. When transmitting an accident report to each report destination, the data stored in this report destination database is used.

The equipment information DB 162 is a database that stores information regarding power system equipment. As shown in FIG. 3, the equipment information DB 162 contains identification information (for example, type (breaker, transformer, generator, power transmission line, etc.), installation location, and normal operating status of power system equipment). For example, in the case of circuit breaker 301CB, the normal operating state is "closed".Therefore, if the operating information sent to the power system accident reporting system 1 is "open", there is some abnormality. It can be assumed that a power system accident has occurred due to this.

The accident information DB 163 is a database that stores accident information collected by the power system accident reporting system 1 when a power system accident occurs. As shown in Figure 4, the accident information DB 163 includes information on the accident location, time of accident occurrence, weather, presence or absence of lightning, presence or absence of work, presence or absence of supply disruption, and power generation disruption for each accident ID assigned to each power system accident. Information on power flow conditions other than the faulty line, state changes caused by the fault, presence or absence of instantaneous voltage drop, failure point (in the case of a transmission line fault), power consumer situation, and civil engineering equipment situation are stored.

The above accident location includes the location where the power system accident occurs, as well as the operational status of equipment and equipment. Information regarding the accident location is obtained from the remote monitoring and control device of each electrical station 2, the information collection and distribution device of the control relay station, and the like.

The accident occurrence time includes the occurrence time down to the second. The accident occurrence time may be acquired from a remote monitoring and control device, an information collection and distribution device of a control relay station, or the like, or the time when abnormal operation information is transmitted may be used as the accident occurrence time.

The presence or absence of lightning is the presence or absence of lightning at the time of occurrence of the accident, and if there is lightning, information including the location of the occurrence is acquired. The presence or absence of lightning and its location are obtained from a well-known lightning position location system.

The presence or absence of work indicates the presence or absence of maintenance work, etc. at the time of the accident occurrence, and if work is being performed, information including the details of the work is acquired. This is because maintenance work and the like may cause accidents. Note that the presence or absence of work and its contents are acquired from a work management system installed in the substation section 7, power transmission section 8, etc.

Regarding the presence or absence of a supply disruption, information is acquired as to whether or not a power supply disruption has occurred due to a power system accident, and if so, the location of the supply disruption and the amount of the supply disruption. In addition, as for whether or not there is a power generation problem, information is acquired as to whether or not the power generation problem is caused by a power system accident, and if so, the location of the power generation problem and the amount of the power generation problem.

Information regarding the supply problem location and the power generation problem location is obtained from, for example, control systems such as the central power dispatch control center 3, the main power supply control center 4, and the control center 5. In addition, regarding the amount of supply disturbance and the amount of power generation disturbance, the amount of supply and power generation during normal times of each power system equipment stored in the equipment information DB 162, the current supply amount and amount of power obtained from the control system such as the control center 5, etc. It is calculated, for example, in the accident information collection task 192 of the main task 19, based on the amount of power generation and the time from the accident occurrence time to the accident convergence time.

Information is obtained on whether or not operating capacity has been exceeded due to power flow conditions other than the faulty line and power system faults. If the operating capacity is exceeded, the power system will be switched, and the number of generators will be increased or reduced. The power flow situation other than the fault line is obtained from, for example, the control systems of the central power dispatch center 3, the main power dispatch control center 4, and the control center 5.

Changes in status caused by an accident include changes in the status of equipment and equipment, as well as the nature of the accident (for example, short circuits and ground faults in 1, 2, and 3 phases), the content of failure indications in control systems such as control centers, and all occurrences. Includes alarms, changes in display, etc. The state change caused by the accident is obtained from, for example, the control systems of the central power dispatch center 3, the main power dispatch control center 4, and the control center 5.

Information on the presence or absence of an instantaneous voltage drop is obtained as to whether or not an instantaneous voltage drop has occurred, and if so, the location where it has occurred. The presence or absence of an instantaneous voltage drop is acquired from, for example, the control systems of the central power dispatch center 3, the main power supply control center 4, and the control center 5.

The failure point is information indicating the location where a failure occurs in a power transmission line in the case of a power transmission line accident. The location of the fault point is obtained from a well-known fault location system.

The status of the electricity consumer is information regarding the area of the consumer where a power outage, voltage drop, etc. are occurring. The status of the electricity consumer is acquired from, for example, the power distribution automation system of the operation control center 6. The status of civil engineering equipment is the status of dams and rivers related to power system accidents, and is obtained from, for example, the civil engineering division 10, which is the location in charge of the equipment.

The track record DB 164 contains performance data on the reporting destination and reporting items for past power system accidents, and the types of power system accidents used to determine the reporting destination and reporting items for past power system accidents. This is a database in which accident information and accident location performance data are stored in association with each other, and is used as training data for generating and updating the report destination determination model 165 and the accident report creation model 166 using machine learning.

The record DB 164 stores record data of power system accidents (power transmission line accidents, substation accidents, power plant accidents, etc.) for each accident ID. FIGS. 5 and 6 show actual data on power transmission line accidents (accident ID: 0143). As can be seen from this performance data, in the case of a power transmission line accident, the accident report is sent to the central power dispatch center 3, the main power dispatch control center 4, and the facilities and departments that need to confirm information about the power line accident and take some kind of response. It is transmitted to the control center 5, operation control center 6, substation section 7, power transmission section 8, hydropower section 9, civil engineering section 10, and public relations section 11 related to the power system accident.

In addition, the items to be reported in the accident report to each reporting destination include items that require confirmation of information regarding the power transmission line accident and any actions that need to be taken at the reporting destination. Incidentally, the accident information stored in the accident information DB 163 is applied to the contents of each report item.

The report contents shown in FIGS. 5 and 6 show the contents of an accident report created based on the report items. For example, the accident report sent to the central power dispatch center 3 reads, ``We are reporting an accident on the 110kV ○△ line 1L transmission line.The accident occurred at 2:21 p.m. on February 13th.The weather was rainy. There was no lightning. 501CB has tripped (ground fault) due to this accident." The report content includes all report items and uses technical terminology used in power system operation and management so that the engineer receiving the report can understand quickly and easily.

On the other hand, for public relations 11, which is a non-technical department, reports are created using general terms that public relations personnel can understand, instead of technical terms used in power system operation and management. . For example, as shown in Figure 6, public information 11 states, ``We would like to report on a power transmission line accident in the ○△ area.The accident occurred at 2:21 p.m. on February 13th.The weather was rainy, and there was no lightning. .Due to this accident, part of the ○△ area is experiencing a power outage.'' In this accident report, instead of technical terms such as "110kV ○△ line 1L" and "501CB tripped (ground fault)," general terms such as "○△ area" and "partial power outage" were used. There is.

FIGS. 7 and 8 show actual data of a substation accident (accident ID: 0087). As can be seen from this performance data, in the case of a substation accident, the accident report is sent to the central power dispatch center 3, the main power dispatch control center 4, and the facilities and departments that need to confirm information about the substation accident and take some kind of response. It is transmitted to the control center 5, operation control center 6, substation section 7, hydropower section 9, civil engineering section 10, and public information 11 related to the power system accident. In addition, the items to be reported in the accident report to each report destination include items that require confirmation of information about the substation accident and matters that require some kind of response at the report destination. Note that, as with the case of power transmission accidents, the accident information stored in the accident information DB 163 is applied to the contents of each report item.

Furthermore, in the case of a substation accident, the content of the accident report sent to a non-technical department such as the public information 11 is different from the accident report sent to a technical department such as the central dispatch center 3. For example, instead of a technical term such as "023TR outage," a general term such as "partial power outage in □△○ area" is used.

FIGS. 9 and 10 show performance data of a power plant accident (accident ID: 0162). As can be seen from this performance data, in the case of a power plant accident, the accident report is sent to the central power dispatch center 3, the main power dispatch control center 4, and the facilities and departments that need to confirm information about the power plant accident and take some kind of response. It is transmitted to the control center 5, the operation control center 6, the hydropower department 9, the civil engineering department 10, and the public information 11 related to the power system accident. In addition, the items to be reported in the accident report to each reporting destination include items that require confirmation of information about the power plant accident and any actions that need to be taken by the reporting destination. Note that, as with the case of power transmission accidents, the accident information stored in the accident information DB 163 is applied to the contents of each report item.

Furthermore, even in the case of a power plant accident, the content of the accident report sent to a non-technical department such as the public information 11 is different from the accident report sent to a technical department such as the central dispatch center 3. For example, instead of technical terms such as "013G outage," general terms such as "partial power outage in △○□ area" are used.

As mentioned above, the Power Transmission Division 8 is excluded from the reporting destination for substation accidents. Furthermore, in the case of power plant accidents, the substation section 7 and the power transmission section 8 are excluded from the reporting destinations. Furthermore, regarding power transmission line accidents, information regarding the accident point is excluded from the items reported to the control center 5 in substation accidents and power plant accidents. Furthermore, the number of items reported to the Hydroelectricity Division 9 in power plant accidents has increased significantly compared to power transmission line accidents and substation accidents.

In this way, depending on the type and location of the power system accident, the facilities and departments that need to confirm information or take some kind of response will differ, and the necessary information will also differ. Report destination and report matters are determined.

Part or all of the equipment information DB 162, accident information DB 163, and track record DB 164 may be stored in an external storage device such as a server. In this case, the power system accident reporting system 1 may acquire various data and information by accessing an external storage device via the communication unit 18, or may acquire various data and information from the external storage device via various signal lines. Various data and information may be obtained by accessing an external storage device via a connection interface (not shown) for transmitting/receiving/inputting/outputting signals such as data and control commands with the device. .

The report destination determination model 165 includes actual data on the report destination and report items for past power system accidents, and the power system data used to determine the report destination and report items for past power system accidents. Machine learning is performed based on the actual data on the type and location of accidents, and when the type and location of a newly occurring power system accident are input, the destination and location of the accident report for the newly occurring power system accident are input. This is a trained model that has been generated to determine and output report items.

The accident report creation model 166 includes performance data of accident reports in past power system accidents, and performance data of report destinations, report items, and accident information used to create accident reports in past power system accidents. Based on the machine learning, when the report destination, report items, and accident information of a newly occurring power system accident are input, the learning machine is generated to create and output an accident report for the newly occurring power system accident. It is a completed model.

The memory 17 temporarily stores information and data generated when the central processing unit 20 executes processes related to determining the report destination and report items, creating the accident report, and transmitting the accident report. It is a storage area/storage device that has the function of serving as a work area for performing tasks, and is composed of, for example, RAM (abbreviation for Random Access Memory).

The communication unit 18 has a function of transmitting/receiving/inputting/outputting signals and information transmitted via various wireless/wired communication networks, including, for example, LAN (abbreviation for Local Area Network) and WAN (abbreviation for Wide Area Network). It is a communication interface equipped with.

The main task 19 is a group of tasks for executing various processes related to creating and transmitting an accident report, which is realized by executing the power system accident report program 161 stored in the storage unit 16.
