Description

  Embodiments described herein relate generally to a power consumption calculation device and a power consumption calculation method.

  In the conventional diagram creation device, when the train travels according to the diagram, the power consumed by the train is not taken into consideration, so it is possible to create a diagram where regeneration invalidation occurs frequently and the power that should be regenerated is wasted There is sex. Here, regenerative invalidation means that there is no power running train that can consume the electric power (regenerative power) returned to the overhead line by the regenerative brake, so the regenerative brake is not effective, and it is converted to electric energy and re-generated by another train. This is a phenomenon in which the kinetic energy that should be used is consumed as heat by the mechanical brake. The regenerative brake is a brake that decelerates the train by converting the kinetic energy of the train into electrical energy and returning it to the overhead line (regeneration) using a motor as a generator. In order to create a diamond with a low possibility of occurrence of regenerative invalidation, it is effective to adjust the diamond while looking at the power consumption considering the regenerative invalidation.

  As a method for calculating the power consumption of a train that travels according to a schedule in consideration of regeneration expiration, there is a method of performing a power simulation according to the train schedule. However, in the power simulation, since the convergence calculation is performed for the overhead line current and the overhead line voltage at all train positions at each time, the processing time required for the power consumption calculation process is long, and the operator confirms the power consumption. It is not suitable for use to adjust the diamond.

  On the other hand, as a simple method of calculating power consumption, the sum of the power running power of all trains and the sum of the regenerative power of all trains at each time is obtained, and the sum of the regenerative power exceeds the sum of power running power. There is a method to judge that mechanical brakes are consumed due to regeneration expiration. Specifically, the power consumption at this time is the sum of powering power at a certain time minus the sum of regenerative power, and if this power consumption is negative or zero, the power consumption at this time is set to zero. The power consumption at each time is integrated. As a result, the power consumption is calculated in consideration of the regeneration invalidation of a certain diamond.

  However, the simple method of calculating power consumption can reduce the processing time used for the power consumption calculation process, but even if the sum of regenerative power is less than the sum of power running power, the train that regenerates power and the train that regenerates Since the case where the regeneration expires due to the long distance between the two is not considered, there is a possibility that the error of the calculated power consumption becomes larger than the power consumption when the train travels according to the diagram. In addition, this method cannot determine when and on which train is likely to cause regeneration invalidation.

  Therefore, in order to support the creation of a diagram that saves energy, the power consumption of a train that takes into account regenerative invalidation is estimated with a shorter processing time than the power simulation and with a higher accuracy than the simple method of calculating power consumption. What can be done is required.

  The power consumption calculation apparatus according to the embodiment includes a database, a storage unit, and a control unit. The database stores a coefficient indicating an effective ratio of regenerative power and power consumption according to vehicle information, route information, and distance between trains. A memory | storage part memorize | stores the diamond information containing the train line and driving curve for every train. The control unit identifies the position of the first train that generates regenerative power and the position of the second train that performs powering at a predetermined time based on the diagram information, and the position of the identified first train and the second train The first coefficient is acquired from the database based on the position of the vehicle, and based on the powering power in the second train obtained using the acquired first coefficient, vehicle information and route information stored in the database. The first train with a smaller regenerative power obtained by using the vehicle information and route information stored in the database than the obtained available power is identified, and the power running power of the second train is determined. Power consumption is calculated by subtracting the regenerative power of the identified first train.

The relationship between the train speed at the location and the relative time) is created. In addition, when the traveling time between stations is not set, the driving curve creation unit 103 creates a fastest driving curve that is a driving curve when the train travels fastest between stations within a range not exceeding the speed limit.

The ideal regenerative power is power that is regenerated from the train to the overhead line when there is no regeneration lapse. In the present embodiment, the operating curve creation unit 103 creates a running curve, calculates power running power, and ideal regenerative power using a known technique.

  The operation curve creation unit 103 causes the display unit 12 to display operation curve information including the created operation curve and the calculated power running power and ideal regenerative power via the input / output interface 101. In addition, the driving curve creation unit 103 outputs the driving curve information from the output unit 13 when the input of the driving curve information is instructed from the input unit 11 via the input / output interface 101. Furthermore, the driving curve creation unit 103 stores the driving curve information in the diamond information storage unit 105.

  Further, the operation curve creation unit 103 sets the travel time of the created operation curve (for example, the fastest operation curve) in a predetermined unit time in accordance with an operator instruction input from the input unit 11 via the input / output interface 101. The standard travel time is set by rounding or adding extra time to the travel time of the driving curve within the travel time between stations. And the driving curve creation part 103 can also store the driving curve information including the standard driving curve changed so that the driving time of the driving curve becomes the set standard driving time in the diamond information storage unit 105.

  The diagram creation unit 104 creates diagram information of a train that travels between the first station and the last station. In the present embodiment, the diagram creation unit 104 includes a train line creation unit 104a, a consistency check unit 104b, and a power consumption calculation unit 104c. The train line creation unit 104a sets a train line creation condition (hereinafter referred to as a train line creation condition) based on information input from the input unit 11 or the display unit 12 (touch panel) via the input / output interface 101. To do. Here, the train line creation conditions are the train operation type (for example, each station stop, express, etc.), train type, travel section (start station and end station), start time of the start station, end station This is the condition when creating train lines, such as the arrival time of

  Then, the train line creation unit 104 a uses the set train line creation conditions, the route information and operation information stored in the database 102, and the operation curve information stored in the diagram information storage unit 105, to generate a train line. Create Specifically, the train line creation unit 104a creates a train line based on the set train line creation conditions (train operation type and travel section) and the operation information (train stop station) stored in the database 102. The station where the train stops is extracted. Next, the train line creation unit 104a corresponds to the set train line creation condition (train type) among the operation curve information stored in the diagram information storage unit 105, and the extracted operation curve between the stop stations or the standard. A train that changes with the passage of time, as shown in FIG. 2, based on a driving curve (hereinafter collectively referred to as a standard driving curve) and a stoppage time included in the operation information stored in the database 102 Train lines (for example, an express train line 201 and a train line 202 at each station stop) are generated. In the present embodiment, the train line creation unit 104a creates a train line using a known technique.

  The train line creation unit 104a corresponds to the set train line creation condition (train type) and the input / output interface 101 when the extracted standard operation curve between the stop stations is not stored in the diagram information storage unit 105. The display section 12 is made to display that the driving curve information satisfying the train line creation condition is not stored in the diagram information storage section 105.

  Further, the train line creation unit 104a moves the train lines of each of a plurality of trains traveling between the first station and the last station in accordance with an operator instruction input from the input unit 11 via the input / output interface 101. By adding or deleting, schedule information that is a train operation plan is created. In this embodiment, the diagram information includes train lines for each of a plurality of trains that travel between the first station and the last station, a train number that is a train line number that allows the train lines to be identified, and a train line that creates the train line. It includes the vehicle type, the stop station of the train that created the train line, the time on the diagram, which is the time when the train travels according to the train line, and the operation curve information including the operation curve of the train traveling between the stations according to the train line. The train line creation unit 104 a outputs the created diagram information from the output unit 13 or stores it in the diagram information storage unit 105 in accordance with an operator instruction input from the input unit 11 via the input / output interface 101. Or

  The consistency check unit 104b responds to an operator instruction input from the input unit 11 via the input / output interface 101, and schedule information and route information stored in the database 102 (boundary section boundaries, signal development information). Based on the above, a consistency check process is executed to determine whether or not the interval between trains traveling according to the created diagram information is greater than or equal to a predetermined interval. In the present embodiment, the consistency check unit 104b executes a consistency check process using a known technique.

  The power consumption calculation unit 104c is configured to operate the train according to the diagram information (that is, the created diagram information) stored in the diagram information storage unit 105 in response to an operator instruction input from the input unit 11 via the input / output interface 101. When the vehicle travels, electric power (energy consumption) consumed from the start time to the end time of the diagram is calculated. In addition, when the start time and end time of the time zone are input from the input unit 11 via the input / output interface 101, the power consumption calculation unit 104c calculates the energy consumption of the time zone. When calculating the energy consumption, the power consumption calculation unit 104c calculates the interchangeable power that is the power that can be consumed by the neighboring trains for each train that is to regenerate power at each time, and the interchangeable power And the regenerative power of the train that is trying to regenerate the power, it is determined whether or not the regenerative invalidation has occurred.

  Then, the power consumption calculation unit 104c, via the input / output interface 101, calculates the diamond energy consumption and the determination result of whether regenerative invalidation has occurred (when regenerative invalidation is likely to occur in which train. Or the like) is displayed on the display unit 12. The operator of the diagram creating apparatus 1 displays the calculation result of the diamond energy consumption displayed on the display unit 12 and the determination result of whether or not regenerative invalidation has occurred (when trains are likely to have regenerative invalidation. It is possible to instruct the input unit 11 to move, add, delete train lines, extend the train stop time, change the train model corresponding to the train lines included in the schedule information, etc. is there.

  Next, power consumption calculation processing by the power consumption calculation unit 104c of the diagram creation apparatus 1 according to the present embodiment will be described with reference to FIGS. FIG. 3 is a diagram for explaining power consumption calculation processing by the diagram creating apparatus according to the present embodiment. FIG. 4 is a diagram showing an example of diagram information created by the diagram creation device according to the present embodiment. FIG. 5 is a diagram for explaining a coefficient assigning process for a train by the diagram creating apparatus according to the present embodiment. FIG. 6 is a flowchart showing the flow of power consumption calculation processing by the diagram creating apparatus according to the present embodiment.

When a time zone for calculating energy consumption is input from the input unit 11 via the input / output interface 101, the power consumption calculation unit 104c receives each time t (predetermined time) in the input time zone as shown in FIG. ), All trains P ₀ , P ₁ , P ₂ , P ₃ , P ₄ (hereinafter referred to as trains P ₀ , P ₁ , P ₂ , P ₃ , P ₄ ) running between the first station and the last station. Are extracted (step S601).

Then, the power consumption calculation section 104c, as shown in FIG. 4, based on the stored timetable information on diagram information storage section 105, the traveling position of each train P at a predetermined time t (e.g., running position of the train P ₀ X _0, the running position _{X 1} of the train _{P 1,} running position _{X 2} of the train _{P 2,} running position _{X 3} of the train _{P 3,} to specify the driving position _{X 4)} of the train _{P 4} (step S602). Further, as shown in FIG. 4, the power consumption calculation unit 104c determines the power running power (for example, the train P) of each train P at the specified travel position from the operation curve information included in the diagram information stored in the diagram information storage unit 105. ₀ power running power B ₀ , train P ₁ power running power B ₁ , train P ₂ power running power B ₂ , train P ₃ power running power B ₃ , train P ₄ power running power B ₄ ) and ideal regenerative power (eg, ideally regenerative power _{R 0} of the train _{P 0,} the ideal regenerative power _{R 1} trains _{P 1,} the ideal regenerative power _{R 2} of the train _{P 2,} the ideal regenerative power _{R 3} train _{P 3,} the ideal regenerative power _R 4 of the train _{P 4)} Is read (step S602). And the power consumption calculation part 104c sets the read ideal regenerative power to the regenerative power of the train P, as shown in FIG. 4 (step S602).

Next, the power consumption calculation unit 104c determines whether or not there is a regenerative vehicle Pi (for example, train P ₂ ) that is a train P whose regenerative power is not “0” (step S603). When the power consumption calculation unit 104c determines that the regenerative vehicle Pi exists (step S603: Yes), the power consumption calculation unit 104c executes the following processing for each regenerative vehicle Pi.

First, the power consumption calculation unit 104c transmits another train P (for example, trains P ₀ , P ₁ , P ₃ , P ₄ ) from the regenerative vehicle Pi (for example, the train P ₂ that is the regenerative vehicle Pi) via an overhead line. The interchangeable power that is the power that can be consumed and consumed is set to “0” (step S604). Furthermore, the power consumption calculation unit 104c determines whether or not there is a train Pk whose relative distance from the regenerative vehicle Pi is equal to or less than the load shareable distance stored in the database 102 based on the identified travel position of each train P. Is determined (step S605). That is, the power consumption calculation unit 104c specifies the position of the regenerative vehicle Pi and the position of the power train Pk based on the diagram information.

When the power consumption calculation unit 104c determines that there is a train Pk (for example, trains P ₁ and P ₃ ) that is a train P whose relative distance to the regenerative vehicle Pi is equal to or less than the load shareable distance (step S605: Yes), A coefficient (hereinafter referred to as power interchangeability) is given to the train Pk whose relative distance to the regenerative vehicle Pi is equal to or less than the load shareable distance (step S606). At that time, the power consumption calculation unit 104c gives the train Pk a degree of power interchangeability that decreases as the relative distance to the regenerative vehicle Pi increases. In the present embodiment, the power consumption calculation unit 104c performs the process of obtaining the power interchangeability for the train Pk, but is not limited to this. For example, the database 102 stores a power interchangeability that is a coefficient indicating an effective ratio of regenerative power and power consumption according to the distance between trains. Then, the power consumption calculation unit 104c may acquire the power interchangeability from the database 102 based on the position of the regenerative vehicle Pi that generates regenerative power at a predetermined time and the position of the train Pk.

In the present embodiment, as shown in FIGS. 3 and 5, the power consumption calculation unit 104 c gives power interchangeability: “1” to the train Pk whose relative distance to the regenerative vehicle Pi is “0”. . The power consumption calculation unit 104c gives the train Pk a degree of power interchangeability that decreases as the relative distance to the regenerative vehicle Pi increases. And the power consumption calculation part 104c gives power interchange ease: "0" with respect to the train Pk whose relative distance is more than the load shareable distance. Specifically, the power consumption calculation unit 104c obtains the power interchangeability to be given to the train Pk using the following formula (1).
Power interchangeability = (X− | xk−xi |) / X (1)
Here, X is a load shareable distance. xk is a travel position of the train Pk. xi is the travel position of the regenerative vehicle Pi.

  In the present embodiment, the power consumption calculation unit 104c gives the power interchangeability by not executing the process for giving the power interchangeability for the train P whose relative distance to the regenerative vehicle Pi is longer than the load shareable distance. However, the present invention is not limited to this, and it is also possible to execute a process of giving power interchangeability to all the trains P other than the regenerative vehicle Pi.

  The power consumption calculation unit 104c adds a value obtained by multiplying the power running power of each train Pk that is powered by the power running ease to the power available for the regenerative vehicle Pi, and power is exchanged for the regenerative power of each train Pk that is regenerated. A value obtained by subtracting the value obtained by multiplying the ease is calculated as interchangeable power that is power that can be consumed from the regenerative vehicle Pi to another train Pk (step S607). In other words, the power consumption calculation unit 104c obtains interchangeable power based on the obtained interchangeable power and the power running power on the train Pk obtained using the vehicle information and route information stored in the database 102. When it is determined that there is no train Pk whose relative distance to the regenerative vehicle Pi is equal to or less than the load shareable distance (step S605: No), the power consumption calculation unit 104c keeps the interchangeable power for the regenerative vehicle Pi at 0. To do.

  When the interchangeable power is calculated for all the regenerative vehicles Pi, the power consumption calculation unit 104c determines whether there is a regenerative vehicle Pi whose regenerative power exceeds the interchangeable power (step S608). When the power consumption calculation unit 104c determines that there is a regenerative vehicle Pi in which the regenerative power exceeds the interchangeable power (step S608: Yes), that is, when the interchangeable power is less than the regenerative power, the train Pi is narrowed down. It can be estimated that regeneration will expire due to In this case, the power consumption calculation unit 104c updates the regenerative power of the regenerative vehicle Pi whose regenerative power exceeds the interchangeable power to “0”. In other words, the power consumption calculation unit 104c identifies the regenerative vehicle Pi whose regenerative power is smaller than the obtained interchangeable power.

  When there are a plurality of regenerative vehicles Pi whose regenerative power exceeds the interchangeable power, the power consumption calculation unit 104c calculates the regenerative power of the regenerative vehicle Pi whose regenerative power greatly exceeds the interchangeable power among the plurality of regenerative vehicles Pi. Set to “0”. Then, the power consumption calculation unit 104c returns to step S603, and repeats the process of calculating the interchangeable power for the regenerative vehicle Pi whose regenerative power is not “0” until there is no regenerative vehicle Pi whose regenerative power exceeds the interchangeable power. The power consumption calculation unit 104c identifies the positions of a plurality of regenerative vehicles Pi that generate regenerative power at a predetermined time based on the diagram information, and the database 102 based on the positions of the identified regenerative vehicles Pi and the train Pk. The power interchangeability is obtained from the power, the power interchangeability for a certain regenerative vehicle Pi, the power running power on the train Pk, and the power interchangeability for other regenerative vehicles Pi and the regenerative power on the other regenerative vehicles Pi. Based on the above, the available electric power is obtained.

  On the other hand, if there is no regenerative vehicle Pi in which the regenerative power exceeds the interchangeable power (step S608: No), that is, if the interchangeable power of the regenerative vehicle Pi exceeds the regenerative power, the power consumption calculation unit 104c is described later. The process proceeds to S610. In this case, it can be estimated that the regenerative electric power of the regenerative vehicle Pi is consumed entirely by the power running of the other trains Pk, and the regeneration invalidation does not occur.

  In the present embodiment, the power consumption calculation unit 104c regenerates the regenerative vehicle when the regenerative power of the regenerative vehicle Pi exceeds the interchangeable power (in other words, when the interchangeable power falls below the regenerative power of the regenerative vehicle Pi). Although it is determined that Pi has expired, the present invention is not limited to this. For example, the magnitude of the regenerative power of the regenerative vehicle Pi exceeding the interchangeable power exceeds the first reference value stored in the database 102. In this case, it may be determined that the regenerative vehicle Pi expires. Thereby, it is possible to consider to some extent the case where the regenerative vehicle Pi is partially invalidated (only a part of the electric power to be regenerated can be regenerated by narrowing down regeneration). In other words, the power consumption calculation unit 104c identifies the regenerative vehicle Pi having a regenerative power smaller than the value obtained by adding the predetermined first value to the interchangeable power as the regenerative vehicle Pi that is partially expired with the regenerative power smaller than the interchangeable power. To do.

  On the other hand, when the first reference value and the second reference value are stored in the database 102, the power consumption calculation unit 104c indicates that the regenerative power of the regenerative vehicle Pi exceeds the interchangeable power in the database 102. When the stored first reference value is exceeded, it is determined that the regenerative vehicle Pi is completely expired, and when it is smaller than the first reference value stored in the database 102 and greater than or equal to the second reference value, the regeneration vehicle Pi It is determined that the car Pi has partially expired, and the regenerative power of the regenerative car Pi is determined according to a value that the regenerative power of the regenerative car Pi exceeds the interchangeable power exceeds the second reference value. Specifically, when it is determined that the regenerative vehicle Pi has partially expired, the power consumption calculation unit 104c reduces the regenerative power of the regenerative vehicle Pi according to a value where the regenerative power of the regenerative vehicle Pi exceeds the interchangeable power. When the magnitude of the regenerative power of the regenerative vehicle Pi exceeding the interchangeable power exceeds the first reference value, the power consumption calculation unit 104c determines that the revocation power is completely invalid and sets the regenerative power to zero. Thereby, the case where the regenerative vehicle Pi partially expires can be considered. The first reference value and the second reference value are set in advance based on the determination result of regenerative invalidation in the past, the result of power simulation, and the like, and are stored in the database 102.

  And the power consumption calculation part 104c calculates the value which deducted the sum total of the regenerative electric power of the train P which regenerates at the time t from the total of the power running electric power of the train P which carries out the power running at the time t as power consumption at the time t ( Step S610). Since the regenerative power of the train determined to be regenerative expired is 0, the power consumption calculating unit 104c can calculate the power consumption considering the regenerative invalidation.

  In addition, when the power consumption calculation unit 104c determines that the regenerative vehicle Pi does not exist (step S603: No), the regenerative power of the train P that regenerates at the time t from the sum of the power running power of the train P that powers at the time t. A value obtained by subtracting the total sum of the powers (in this case, the sum of the regenerative power is 0) is calculated as the power consumption at time t (step S610). The power consumption calculation unit 104c repeats the above-described process for all times t in the input time zone.

  Thereafter, the power consumption calculation unit 104c integrates the power consumption calculated for all the times t in the input time zone to obtain the energy consumed in the train schedule in the input time zone (step S611). ).

  Next, with reference to FIG. 7, the flow of the operation curve creation process performed by the diagram creation device 1 according to the present embodiment will be described. FIG. 7 is a flowchart showing a flow of a process for creating an operation curve by the diagram creating apparatus according to the present embodiment.

  The operation curve creation unit 103 receives from the input unit 11 via the input / output interface 101 the departure / arrival station of the train that creates the operation curve, the train line at which the train stops, the train type, the specified overhead line voltage, and the speed limit When the margin up to is input, the operating curve creation conditions are set (step S701).

  The driving curve creation unit 103 creates a driving curve for each station where the train stops between the departure and arrival stations, using the set driving curve creation conditions and the route information and vehicle information stored in the database 102 (steps). S702). If the traveling time between stations is not set as the driving curve creation condition, the running curve creation unit 103 creates the fastest running curve when the train travels the fastest between the stations within a range not exceeding the speed limit. Further, the operation curve creation unit 103 causes the display unit 12 to display the created operation curve via the input / output interface 101.

  The driving curve creation unit 103 displays the created driving curve on the display unit 12, and when the travel time is input from the input unit 11 via the input / output interface 101, the driving curve creation unit 103 converts the input travel time to the standard travel time. (Step S703). Then, the operation curve creation unit 103 changes the created operation curve so that the travel time of the train between the stations becomes the standard travel time (step S704). Further, the operation curve creation unit 103 causes the display unit 12 to display the changed operation curve via the input / output interface 101.

  When the driving curve creation unit 103 displays the changed driving curve on the display unit 12, the driving time is input again from the input unit 11 via the input / output interface 101, and an instruction to change the driving curve is given. (Step S705: Yes), the process returns to Step S704. On the other hand, when the operation curve change unit 103 has not been instructed to change the operation curve (step S705: No), the operation curve information including the changed operation curve is stored in the diagram information storage unit 105 (step S706). . The driving curve creation unit 103 repeats creation of driving curve information including driving curves between all stations where the train stops between the departure and arrival stations in both the upward and downward directions between the departure and arrival stations.
