Description

Technical Field

[0001] The present invention relates to a power outage plan processing device and a power outage plan processing method.

Background Art

[0002] In an electric railway, construction, maintenance, and inspection work on the electric power facilities are carried out in a state where the electric power supply in the electrified section is cut off. Therefore, it is necessary to investigate in advance the time zone when trains do not run in the electrified section. The time zone when trains do not run in the electrified section is called the power outage availability.

[0003] In setting the power outage availability, since trains may not run at the planned time due to reasons such as train schedule disruptions on the day of the power outage, it is necessary to investigate in advance several trains that may be the last to run in the electrified section. In the following description, the train that is the last to run in the electrified section when setting the power outage availability is referred to as the availability train. On the day of the power outage, after confirming the operation record of the availability train, it is necessary to cut off the power supply in the electrified section. Conventionally, the power outage availability plan has been made manually by railway company staff based on the electric power system and the train schedule. Here, in order to appropriately create the power outage availability plan, in addition to the train schedule, knowledge such as the details of the power transmission facilities in the electrified section is required, and there is a problem that it cannot be easily created.

[0004] For this reason, for example, as described in Patent Document 1, a power outage availability extraction processing device that automatically creates the power outage availability from the train schedule has been developed. That is, Patent Document 1 describes a power outage availability extraction processing device that extracts the confirmation trains located within the power outage availability section using the inter-station bitmap and the train schedule database, and extracts the power outage availability that does not affect the train schedule.

Patent Document 1

[0006] The train schedule database required for the power outage interval extraction processing device described in Patent Document 1 requires detailed information such as the times when trains pass through, turn around, arrive at their final destination, and when the pantographs are lowered after arrival at each station. Therefore, when applying the technology described in Patent Document 1, it is necessary to input this detailed information into the train schedule database, which presents the problem that creating a detailed train schedule database is cumbersome.

[0007] Furthermore, in the case of construction, maintenance, or inspection work on power supply equipment, if only the power supply equipment for one direction of the line (either the up or down line) is shut off, it is possible to travel on the line in the direction that is not shut off. However, the technology described in Patent Document 1 does not take such travel in only one direction into consideration.

[0008] Furthermore, if only the power supply equipment is being worked on and the track signaling system is operational, trains that do not require power from the overhead lines, such as diesel railcars, can run even during the work. However, the technology described in Patent Document 1 does not consider the case where diesel railcars that are not affected by the power outage period are running.

[0009] The present invention aims to provide a power outage planning processing device and a power outage planning processing method that enable simple and accurate planning of power outages and the duration of power outages when shutting down railway lines. [Means for solving the problem]

[0010] To solve the above problems, for example, the configuration described in the claims is adopted. The present invention includes several means for solving the above-mentioned problems, but to give one example, as a power outage planning processing device, it plans the interval between power outages in order to set the power outage schedule for electric railways, and the configuration of the power outage planning processing device includes a train confirmation section creation unit that creates train confirmation sections for power outage sections, a storage unit that stores past power outage records and actual timetables, and a power outage planning unit that plans the interval train, which is the train immediately before the interval between power outages, and the scheduled power outage time, based on the power outage section, the train confirmation section, the scheduled timetable, past power outage records, and the actual timetable. [Effects of the Invention]

[0011] According to the present invention, it is possible to appropriately plan the interval trains and scheduled power outage times based on the scheduled timetable, past power outage records, and actual timetables. For example, by inputting only arrival and departure operational types into the scheduled timetable, it becomes possible to plan appropriate interval trains and scheduled power outage times. Other issues, configurations, and effects not mentioned above will be clarified by the following description of the embodiments. [Brief explanation of the drawing]

[0012] [Figure 1] This is a diagram showing an example of a power outage planning processing device according to one embodiment of the present invention. [Figure 2] This flowchart shows an example of a power outage planning process (first half) according to one embodiment of the present invention. [Figure 3] This flowchart shows an example of power outage planning processing according to one embodiment of the present invention (the latter half). [Figure 4] This figure shows an example of a power outage planning process according to one embodiment of the present invention. [Figure 5] This figure shows an example of past data, scheduled timetable, interim trains, and scheduled power outage times used in power outage planning processing according to one embodiment of the present invention. [Modes for carrying out the invention]

[0013] Hereinafter, a power outage plan processing apparatus and a power outage plan processing method according to an embodiment of the present invention (hereinafter referred to as "this example") will be described.

[0014] [Configuration of the apparatus] FIG. 1 shows the configuration of the entire system including the power outage plan processing apparatus of this example. The power outage plan processing apparatus of this example is constituted by a railway power management server 200. Here, the railway is an electric railway in which trains (vehicles) receive power supply from overhead lines or the like and run using that power. However, even in the case of an electric railway, some trains that run may be pneumatic vehicles or diesel locomotives that do not require power supply. The power management server 200 manages the power supplied to trains via overhead lines or the like.

[0015] The power management server 200 is configured to be able to communicate with the railway operation management server 100. These operation management server 100 and power management server 200 are each configured as a computer constituted by a CPU (central processing unit), a memory, an input / output interface, etc., and execute their respective management processes by executing programs stored in the memory. For example, as shown in FIG. 1, the power management server 200 is configured as a computer in which a CPU 200a, a memory 200b, a storage 200c, and a communication interface 200d are interconnected by a bus line. The operation management server 100 also has the same hardware configuration as the power management server 200.

[0016] Various settings are performed on the operation management server 100 and the power management server 200 by operating a user terminal 300 which is a terminal owned by a railway operator. Then, the processing results in the operation management server 100 and the power management server 200 are displayed on the user terminal 300. The operation management server 100 and the power management server 200 transmit and receive data to and from the user terminal 300 via a predetermined network. The user terminal 300 is a computer having a display unit 301 and an operation unit 302.

[0017] The operation management server 100 includes a scheduled train schedule management unit 101 and an actual train schedule management unit 102. The scheduled train schedule management unit 101 holds train operation schedules (scheduled schedules) for the current day and several days after the next day. The actual train schedule management unit 102 holds train operation schedules (actual schedules) for the past several days. These scheduled schedules and actual schedules have information on at least the arrival and departure times of trains at each station (hereinafter abbreviated as "arrival / departure").

[0018] Note that the fact that the scheduled train schedule management unit 101 and the actual train schedule management unit 102 hold train operation schedules for several days in the future and past is just an example. The scheduled train schedule management unit 101 and the actual train schedule management unit 102 may hold train operation schedules for a longer period in the future and past actual schedules. Also, the scheduled train schedule management unit 101 and the actual train schedule management unit 102 may have information such as the track number where arrival / departure occurs in addition to the information on the arrival / departure times of each station as the scheduled schedule and actual schedule.

[0019] The power management server 200 includes a work input unit 201, a power outage record management unit 202, a planned display change unit 203, a storage unit 210, and a processing unit 220. The work input unit 201 receives an input of a work section that requires a power outage from the user terminal 300. The power outage record management unit 202 holds at least the power outage records for the past several days. The planned display change unit 203 displays the power outage schedule on the user terminal 300. Also, the planned display change unit 203 can allow the user to edit the power outage schedule by operating the user terminal 300.

[0020] The storage unit 210 performs a storage process of accumulating data necessary for the power outage schedule. That is, the storage unit 210 includes a substation location database 211, a past database 212, and a teacher database 213. In the drawings, "database" is described as "DB". The substation location database 211 stores data including items such as the positional relationship between substations and stations.

[0021] The past database 212 stores historical timetable data, including items such as train departure and arrival times, train numbers, stations, and departure / arrival dates, which are entered from the operational timetable management unit 102 of the operation management server 100. The past database 212 also stores historical power outage data, including items such as power outage times, sections affected, power outage control procedures, and power system status, which are entered from the power outage history management unit 202. The teacher database 213 stores power outage interval data, which includes information such as train schedules, scheduled power outage times, and power outage control procedures that have been edited in the past by the schedule display change unit 203.

[0022] Next, the configuration and functions of the processing unit 220 will be described. The processing unit 220 includes a power outage section creation unit 221, a train confirmation section creation unit 222, a power outage planning unit 223, a power outage control procedure planning unit 224, and a system simulation unit 225. The power outage section creation unit 221 creates power outage sections based on instructions from the user terminal 300. The train confirmation section creation unit 222 creates train confirmation sections for the power outage sections created by the power outage section creation unit 221 (train confirmation section creation process).

[0023] The power outage planning unit 223 creates a power outage plan (power outage plan creation process) based on the power outage section, the train confirmation section, the planned timetable, past power outage records, and the actual timetable. The power outage plan created here is a plan to create the interval train, which is the train immediately before the power outage, and the scheduled power outage time. The specific process for planning the interval train and the scheduled power outage time is explained in the flowcharts in Figures 2 and 3. The power outage control procedure planning unit 224 plans the power outage control procedure to be used when executing the power outage plan created by the power outage planning unit 223. The system simulation unit 225 simulates the power outage control procedure created by the power outage control procedure planning unit 224.

[0024] [Flowchart for processing power outage plans] Figures 2 and 3 are flowcharts illustrating an example of the power outage planning process performed by the power management server 200 in this example. The processes from step S11 to step S27 shown in Figures 2 and 3 will be explained in order below. Note that the "A" after step S21 in Figure 2 corresponds to "A" in Figure 3, and the "B" after NO in step S25 in Figure 3 corresponds to "B" in Figure 2.

[0025] When processing begins, the user inputs the work section requiring a power outage, including items such as the work date, the distance between stations, and whether it is an up-line or down-line, using the user terminal 300 (step S11). This information entered on the user terminal 300 is then input into the work input unit 201.

[0026] Next, the power outage section creation unit 221 creates the necessary power outage sections for the work based on the work sections entered in the work input unit 201 and the information in the substation layout database 211 (step S12). Furthermore, the train confirmation section creation unit 222 creates a train confirmation section that includes stations where train arrival and departure records need to be confirmed before the power outage, based on the power outage section created by the power outage section creation unit 221 and the information from the substation location database 211 (step S13).

[0027] Figure 4 shows an example of creating power outage sections and train inspection sections based on the work section and substation layout. The example shown in Figure 4 illustrates a section of a double-track electric railway consisting of an up-line and a down-line, where stations a, b, A substation, c, d, B substation, e, and f are arranged in that order. Information on the arrangement of these stations and substations is stored in the substation arrangement database 211.

[0028] Here, the section of the up line between station c and station d is designated as a work section where the power is to be turned off. At this time, the power outage section creation unit 221 extracts the section of the up line between substation A and substation B, which includes the work section between station c and station d, as the power outage section. Furthermore, the train confirmation section creation unit 222 extracts the section from station b to station e, which includes the power outage section between substation A and substation B, as the train confirmation section.

[0029] Returning to the flowchart in Figure 2, let's continue explaining the flow of the power outage planning process. The power outage planning unit 223 extracts a predetermined number of past power outage data, for example a maximum of 100 data points, from the past database 212 for the power outage sections created in step S12 (step S14). Then, the power outage planning unit 223 extracts one of the past power outage data extracted in step S14 and extracts the actual timetable for the same day as that power outage from the past database 212 (step S15).

[0030] Here, "the same day" refers to the same day of the week, etc., to which the same timetable applies. Then, the power outage planning unit 223 extracts the train arrival and departure records for stations within the train confirmation section created in step S13 from the extracted actual timetables. Next, the power outage planning unit 223 determines, based on the power outage history and train arrival / departure history extracted in step S15, train arrival / departure history up to, for example, 30 minutes prior to the power outage time as candidate trains for the interval (step S16).

[0031] Next, the power outage planning unit 223 determines that train departures and arrivals that occur after the time of the power outage are not included in the calculation of "interim trains" (step S17). Then, the power outage planning unit 223 performs the processing in steps S15 to S17 on all of the past power outage data extracted in step S14.

[0032] Next, the power outage planning unit 223 excludes trains that are not eligible for the interval from the train interval candidates and confirms the train interval candidates (step S18). Then, the power outage planning unit 223 extracts the scheduled timetable, including items such as the scheduled time, train number, station, and departure / arrival dates for the work day entered in step S11, from the scheduled timetable management unit 101 of the operation management server 100 (step S19).

[0033] Furthermore, the power outage planning unit 223 extracts the scheduled departure and arrival times of candidate trains for the gap trains confirmed in step 108 from the scheduled timetable extracted in step S19, and determines that they are gap trains (step S20). Then, the power outage planning unit 223 determines that the scheduled power outage time is, for example, one minute after the last extracted train (step S21).

[0034] Figure 5 shows an example of data created in steps S14 to S21, where gap trains and scheduled power outage times were generated from past data and the planned timetable. In step S14, historical data D11 and D12 were extracted from the historical database 212. In step S15, the data extracted for power outage history and train arrival / departure history consists of items such as actual time 501, train number (train number) 502, and actual details 503. Actual details 503 shows the arrival or departure time at each station in this section and the time the power outage occurred.

[0035] In the first historical data D11 for the inbound line between Substation A and Substation B shown in Figure 4, train numbers 2222M, 3333M, and 4444M are candidates for off-peak trains T11, while 6666D and 7777M are not considered as off-peak trains T12. In addition, in the second historical data D12 for the inbound line between Substation A and Substation B, train numbers 7777M, 1111M, and 6666D are candidates for off-peak trains T21, while 8888D and 2222M are not considered as off-peak trains T22.

[0036] Therefore, from the past data D11 and D12 for the up line between Substation A and Substation B, three trains—train numbers 1111M, 3333M, and return train 4444M—are identified as candidates for off-peak trains. The "M" at the end of the train number indicates that the train is an electric train, and the "D" indicates that the train is a diesel train. The "Return" at the beginning of the train number indicates that the train is a non-revenue train. In the example in Figure 5, train number 6666D is not an electric train, so it can run even in the section where there is a power outage.

[0037] As shown in Figure 5, the scheduled timetable Da extracted by the power outage planning unit 223 from the scheduled timetable management unit 101 in step S19 consists of items such as the scheduled time 504, train number 502, and scheduled content 505. Train numbers 1111M, 3333M, and 4444M, which were determined to be candidates for intermediate trains, also exist in the planned timetable Da shown in the upper right of Figure 5, and are therefore determined to be intermediate trains on the up line between Substation A and Substation B.

[0038] Therefore, as shown in the lower right of Figure 5, the interim trains created by the power outage planning unit 223 will be train numbers 1111M, 3333M, and return train 4444M, and the scheduled power outage time on the up line between substation A and substation B will be one minute after return train 4444M arrives at station e.

[0039] Furthermore, in order to determine that trains not present in past data are "off-peak trains," the power outage planning unit 223 may also determine trains from the scheduled timetable that have a high correlation with the actual timetables in past data as candidates for off-peak trains. Furthermore, when the power outage planning unit 223 determines potential trains for the same power outage section, it may use past edited data stored in the data for the same power outage section of the teacher database 213 as potential trains for the same section.

[0040] The operational status item in the saved past editing data of teacher database 213 may include not only arrival and departure within the relevant section, but also station operations such as lowering the train's pantograph (so-called pantograph lowering) and shunting trains within the station premises.

[0041] Because the power supply system extends to the station premises of stations that trains pass through, conventionally, when users set up interim trains between up and down power supply sections, they had to check detailed power supply system information and train route information on paper, such as which power supply section the tracks of stations the trains pass through belong to, and whether there are any down power supply sections on the tracks that up trains pass through. In addition, diesel railcars that would not be affected by power outages had to be excluded from interim trains.

[0042] The power outage planning unit 223 can determine candidate trains for the off-peak hours based on past data and training data, without having to create a database of power system information that is not detailed, train route information, and diesel railcars that will not disrupt the power outage interval. Furthermore, while in many cases the operational patterns on the actual timetable and the planned timetable only show arrivals and departures, this example allows for the determination of trains with gaps in service without having to input data on detailed operational patterns such as passing through, turning around, terminating, and lowering the pantograph at the end of service into the actual timetable and the planned timetable.

[0043] Returning to the flowcharts in Figures 2 and 3, let's continue explaining the flow of the power outage planning process. The following processes occur after the power outage planning unit 223 sets the interim trains and power outage times. The power outage control procedure planning unit 224 extracts power outage control procedures with a high correlation from the power outage plan planned by the power outage planning unit 223 and the past power outage times, power outage control procedures, and power system status in the database (step S22). The power outage control procedure planning unit 224 can reflect past edited data stored in the data for the same power outage section in the teacher database 213 into the power outage control procedure.

[0044] Next, the system simulation unit 225 simulates all of the power outage control procedures for the scheduled power outage date created by the power outage control procedure planning unit 224 (step S23). Based on the result of step S23, the power outage control procedure planning unit 224 determines whether or not the planned power outage section will experience a power outage (step S24).

[0045] For example, if there is a power outage plan in which the planned power outage section will not be affected by extended power supply from an adjacent substation (NO in step S24), the power outage control procedure planning unit 224 determines that there is a problem with the control procedure created by the system simulation unit 225, and the power outage control procedure planning unit 224 returns to the process in step S22 and creates the power outage control procedure again. Furthermore, if all planned power outage sections experience power outages (YES in step S24), the process proceeds to the next step, S25.

[0046] In other words, the power outage control procedure planning unit 224 determines whether or not there are any power outage sections other than the planned power outage section (step S25). Here, for example, if a section other than the planned power outage section is affected by the shutdown of an adjacent substation (NO in step S25), it is determined that there is a problem with the created power outage section, and the process returns to B in Figure 2 (step S13). In other words, if there is a problem with the power outage section in step S25, the process returns to step S13, and the train confirmation section creation unit 13 executes the power outage plan again. If there are no power outage sections other than the planned power outage section (YES in step S25), the process moves to the next step S26.

[0047] The system simulation unit 225 then simulates all power outage control procedures for the scheduled power outage date, and if the planned power outage section matches the simulated power outage section, it causes the plan display change unit 203 to display the power outage plan (step S26). As a result, the power outage plan is displayed on the display unit 301 of the user terminal 300.

[0048] Next, the plan display modification unit 203 displays information including the created gap trains, scheduled power outage times, and power outage control procedures on the display unit 301 of the user terminal 300. The user then edits any data displayed on the display unit 301 using the operation unit 302, and the edited data is saved as training data in the training database 213 (step S26). In this way, by saving the edited data in the teacher database 213, the power outage planning unit refers to the saved teacher data when executing a power outage plan and creates a power outage plan that reflects the content edited by the user.

[0049] [Effects of one embodiment] According to the power outage planning processing device and method of this example, it is possible to appropriately plan interim trains and scheduled power outage times based on the planned timetable, past power outage records, and actual timetables. In other words, according to this example, based on the actual timetable of past power outage sections, train arrival and departure records up to a certain time before the actual power outage time (for example, 30 minutes before) are designated as candidates for interim trains, and from these candidates, it is possible to select appropriate interim trains and plan the scheduled power outage times. Furthermore, the operational information to be entered into the planned timetable only needs to be the arrival and departure times of trains in the power outage section, and there is no need to enter detailed operational information, so it becomes easy to plan interim trains and scheduled power outage times.

[0050] Furthermore, according to this example, by obtaining past timetable data to determine potential replacement trains, it is possible to determine from the past timetable, for example, when there is a power outage on the up line between certain stations, and a down line train enters the powered section of the up line at a station within that section. Therefore, it becomes possible to select more appropriate replacement trains according to the actual timetable.

[0051] Furthermore, trains that can operate even during a power outage, such as diesel railcars and diesel locomotive-hauled trains, are excluded from the off-peak trains, which also allows for the creation of an appropriate power outage plan. However, if signaling or other operations are carried out simultaneously with the power outage in the relevant section, it is necessary to create a power outage plan that includes all trains, including diesel railcars, as candidates. For this reason, when creating a power outage plan using the power outage planning processing device in this example, it is preferable to be able to select in advance whether to only perform a power outage that stops the power supply to the relevant section, or to stop all train operations in the relevant section during the power outage.

[0052] Furthermore, the power outage control procedure planning unit 224 of the power management server 200 plans the power outage control procedure, and the system simulation unit 225 simulates it. By checking this on the user terminal 300, the user can determine whether the power outage control procedure is appropriate or not. In other words, if the simulation result from the system simulation unit 225 is not appropriate, the power outage control procedure planning unit 224 can create an appropriate power outage plan by executing the power outage plan again, including the idle trains and the scheduled power outage time, based on that simulation result.

[0053] For example, in the flowchart shown in Figure 2, step S21 sets the planned power outage time to one minute after the scheduled train. However, simulation results may show that a power outage one minute later is not appropriate, allowing for the creation of a more appropriate power outage plan based on actual operational data.

[0054] [Differentiation] The power outage planning processing device and power outage planning processing method of the present invention are not limited to the configurations and processes described in the above-described embodiments, and various modifications can be implemented without departing from the gist of the invention as described in the claims. Furthermore, the above-described embodiments are described in detail for the purpose of clearly explaining the present invention, and are not necessarily limited to those having all the configurations described.

[0055] For example, the above-described embodiment showed an example of application to a double-track electric railway consisting of an up line and a down line. In contrast, the present invention can also be applied to single-track electric railways and quadruple-track electric railways. Furthermore, in the above-described embodiment, the planned timetable and actual timetable included at least arrival and departure information for each station, but it may also include more detailed timetable information.

[0056] Furthermore, in the configuration shown in Figure 1, the operation management server 100 and the power management server 200 are separate servers, and the user terminal 300 accesses each server. However, this system configuration is also just one example. For example, data such as scheduled timetables, actual timetables, and historical data on power outage sections may be stored in a storage device located separately from these servers, and the operation management server 100 and the power management server 200 may read the information from the storage device. Alternatively, a processing unit equivalent to the processing unit 220 of the power management server 200 may be provided within the user terminal 300, allowing the user terminal 300 to create power outage plans, etc. [Explanation of symbols]
