Description

  The present invention relates to a period estimation system and a period estimation program required for power supply for estimating a period required to supply power (electricity) to a newly built house or the like.

  For example, when power is supplied to a newly built house, the following procedures and processes have been conventionally performed. First, when a consumer (a purchaser of a house) performs a procedure for purchasing a house from a construction company, the construction company requests the construction of an electrical facility from the construction company. Then, the construction company and the electric construction shop discuss and determine the power load facility, the pull-in method, the indoor wiring method, the scheduled start date (delivery date) of electricity, and the like. After that, an electrician applied to the electric power company from the electric construction shop, and the electric power company's designer in charge determined whether construction or the like was required to supply the electric power suitable for the application. In other words, the design engineer made decisions such as whether or not external work such as the construction of a transformer or utility pole was necessary, and whether or not it was necessary to apply for private use to the competent authority in order to cross the national highway.

There is also known a system for determining whether or not it is necessary to circulate application details for electricity usage from a customer to a design department of an electric power company (see, for example, Patent Document 1). This system identifies the power application range from the contract type included in the application content, and circulates the application content to the design department by determining whether or not this power application range exceeds the allowable power capacity. It is determined whether or not it is necessary.
JP 2007-299046 A

  By the way, as a result of the examination by the design person in charge of the electric power company, it takes a long time to supply the electric power if an outside line construction is required or a private application is required to the competent authority. However, in the conventional procedures / processes described above, after the construction company and the electric construction shop discuss and determine the scheduled start date of the use of electricity, the electric construction shop applies to the electric power company for use of electricity. In addition, the scheduled start date for using electricity is determined based on the desires of consumers. That is, the scheduled start date of electricity is determined regardless of whether or not the outside line construction is necessary and whether or not an application to the competent authority is required. For this reason, when an outside line construction or an application to the competent authority is required, there may be a situation where power cannot be supplied by the scheduled start date of use. In particular, when it takes a long time to apply to an electric power company from an electric construction shop, the period during which outside line construction or application to the competent authority will be shortened, and power will be used by the scheduled start date of use. There may be situations where it is not possible to supply And in order to avoid such a situation, it is possible for construction companies, electric construction shops and even customers to know the period until electricity can be used, that is, the period required to supply power. Is desired.

  According to the first and second aspects of the present invention, the work for supplying power based on the planned location or planned load where the power is used and the type, capacity, installation location, etc. of the power facility, Necessity of application for approval and notification is determined, and based on the result, the period required to supply power is estimated. That is, an appropriate period for supplying electric power that meets the demands of the consumer can be estimated in consideration of work such as outside line construction and application to the competent authority. Then, by sharing this estimation result with a construction company, an electric construction shop, or even a customer, it is possible to know a period until electricity can be used.

  The present invention will be described below based on the illustrated embodiments.

  FIG. 1 is a schematic configuration diagram showing a period estimation system (hereinafter referred to as “period estimation system”) 1 required for power supply according to an embodiment of the present invention. This period estimation system 1 is a system that estimates the period required to supply power that meets the demands of the customer. The personal computer (specification input means) 2 and the estimation server 3 configure a communication network (Internet) NW. Via a communicable connection. In this embodiment, the personal computer 2 is installed in an electric construction shop, and the estimation server 3 is installed in an electric power company.

  The personal computer 2 includes a keyboard and a mouse, and is a terminal for inputting power requirement specifications such as a planned place where power is used and a planned load. That is, as will be described later, the application reception task 31 is activated by accessing the Web page of the estimation server 3, and the power requirement specification is input according to the input screen by the application reception task 31. In addition, the input power requirement specification is transmitted to the estimation server 3 by performing a transmission operation. Here, the power requirement specification specifically includes the name and address of the customer who is the applicant, the number of the utility pole from which power is drawn, the planned load, the contract type, the scheduled start date of use of electricity, and the like.

  The estimation server 3 mainly includes an application reception task (specification receiving means) 31, an equipment database (storage means) 32, a work indexing task (work indexing means) 33, an estimation task (estimating means) 34, and these And a central processing unit 35 for controlling the above.

  The application reception task 31 is a task for receiving the power requirement specification input by the personal computer 2. That is, an electricity usage application menu in the Web page of the estimation server 3 is configured, and when this menu is accessed, an input screen for inputting power requirement specifications is displayed. Then, as described above, when the power requirement specification is input and transmitted to the estimation server 3 according to this input screen, the power requirement specification is read and stored in the memory.

  The equipment database 32 is a database that stores equipment information such as the type and capacity of the existing power equipment owned by the power company, the installation location, and the usage status (bank load status, etc.) of each equipment. Specifically, for example, in the utility pole data 321 shown in FIG. 2, for each utility pole number for identifying the utility pole, the power capacity (transformer capacity) of the transformer installed on this utility pole and the power pole data 321 are drawn from this transformer. The contracted power capacity (existing contracted capacity) of the customer who is in charge is stored. The utility pole data 321 is referred to in the work indexing task 33 described later in order to determine whether the power capacity is sufficient when, for example, a new consumer is connected to an existing transformer. Further, in the map data 322 as shown in FIG. 3, the position / installation location of each electric power facility is stored on the map. Here, “●” in the figure indicates a power pole, and a broken line indicates a distribution line. And this map data 322 is referred in order to determine whether to occupy a national highway etc. in the work indexing task 33 described later.

  The work indexing task 33 is based on the power requirement specification received by the application reception task 31 and the facility information stored in the facility database 32, and the work required to supply power that conforms to the power requirement specification, It is a task (program) that determines whether or not a license application or notification is required to perform this work. Specifically, it comprises a first indexing task 331 for determining work and a second indexing task 332 for determining whether or not an application is necessary.

  In the first indexing task 331, as shown in FIGS. 4 and 5, it is first determined whether or not the power requirement specification is a new application for high-voltage power (step S1). If it is a new application for high-voltage power, it is determined on the basis of the equipment database 32 whether or not a power pole with a high-voltage line is installed near the power receiving point (customer's house) (step S2). As a result, when the high piezoelectric column is installed, the necessary work is set as the extension of the high voltage line, and the “high voltage line extension work” is stored in the work area of the memory (step S3). On the other hand, if the high piezoelectric pole is not installed, the necessary work is newly installed as a utility pole and a new high-voltage line, and “electric pole + high-voltage line new construction” is stored in the work area of the memory (step S4).

  If the power requirement specification is not a new application for high-voltage power in step S1, it is determined based on the power requirement specification and the facility database 32 whether or not it is an application for power load supply to a single-phase line (step S5). And when it is an application of power load supply to a single phase track, it is judged based on equipment database 32 whether the single phase track is a high voltage track or a low voltage track (Step S6). As a result, in the case of a high-voltage line, the necessary work is changed to a three-phase high-voltage line, and “high-voltage three-phase construction” is stored in the work area of the memory (step S7). On the other hand, in the case of a low-voltage line, the necessary work is made into a three-phase low-voltage line, and “low-pressure three-phase construction” is stored in the work area of the memory (step S8).

  If it is not an application for power load supply to the single-phase line in step S5, it is determined based on the power requirement specification and the facility database 32 whether or not a power pole is installed within a predetermined range from the customer's house (step S5). S9). If the utility pole is not installed, the necessary work is set as a new utility pole, and “new utility pole construction” is stored in the work area of the memory (step S10). Here, when a power pole number is included in the power requirement specification, the power pole with this power pole number is set as a power pole near the customer's house, and the same applies to the following processing.

  If a power pole is installed near the customer's house in step S9, it is determined based on the equipment database 32 whether or not a transformer and a low-voltage line are installed on the power pole (step S11). If no transformer or low-voltage line is installed, it is determined based on the equipment database 32 whether or not the low-voltage line can be extended from another utility pole having a low-voltage line to a utility pole near the customer's house. (Step S12). As a result, if the extension is possible, the necessary work is set as the extension of the low voltage line, and “low voltage line extension work” is stored in the work area of the memory (step S13). On the other hand, if the extension is impossible, the necessary work is newly installed, and “transformer new construction” is stored in the work area of the memory (step S14).

  When a transformer and a low voltage line are installed on the utility pole near the customer's house in step S11, the amount of power of the transformer and the like are calculated (step S15). That is, based on the power requirement specification and the facility database 32, the amount of power of the lamp transformer, the amount of voltage drop, and the value of the current flowing through the low voltage line when power is supplied according to the power requirement specification are calculated. If the calculated power amount of the light transformer exceeds the allowable value (for example, 160% of the capacity) of the transformer (in the case of “Y” in step S16), the necessary work is replaced with the transformer. And "transformer replacement work" is stored in the work area of the memory (step S17).

  If the calculated voltage drop exceeds a preset allowable value (for example, 5 V) (in the case of “Y” in step S18), the necessary work is taken as the movement of the transformer, and the work of the memory is performed. The “transformer moving work” is stored in the area (step S19). The necessary work may be modulation of a high voltage line. Furthermore, when the calculated current value flowing through the low-voltage line exceeds the allowable current value determined for each line type (wire diameter) (in the case of “Y” in step S20), the necessary work is performed on the low-voltage line. The line type is changed (changed to a thicker wire diameter), and “low-voltage line change work” is stored in the work area of the memory (step S21). The necessary work may be divided into loads.

  On the other hand, when it does not correspond to these external line works (in the case of “N” in step S20), the necessary work is regarded as work that does not require external line work, and “non-external line work” is stored in the work area of the memory (step S22).

  As described above, in the first indexing task 331, only one operation is determined for one power requirement specification, but a plurality of operations may be determined. That is, for example, the process proceeds to step S5 after the process of step S3 or S4, and further proceeds to step S9 after the process of step S7 or S8. .

  In the second indexing task 332, as shown in FIG. 6, first, the positional relationship of work (construction) is examined (step S31). That is, the work and power requirement specifications determined by the first indexing task 331, such as the position of the lead-in line drawn from the power pole to the customer's house, the relationship between the work pole and the place (road) necessary for the work, etc. And based on the equipment database 32, it is determined. As a result, as shown in Fig. 7, when a new service line crosses and traverses national roads, prefectural roads, rivers, etc. (occupies the sky) or installs utility poles on public land (case 1), It is determined that an application is necessary, and “occupation application” is stored in the application application area in the memory (step S32).

  Similarly, when traffic restrictions are imposed for outside line construction and national roads are temporarily occupied (case 2), it is determined that a temporary occupation application is required, and a “temporary occupation application” is entered in the memory application area, etc. Store (step S33). Further, when the work is a simple work on the sidewalk (case 3), it is determined that the work report is necessary, and “work report” is stored in the memory application area (step S34). On the other hand, if none of the cases 1 to 3 is applicable, it is determined that the application is unnecessary, and “unnecessary” is stored in the application application area of the memory (step S35).

  The estimation task 34 is a task for estimating a period (necessary period) required to supply power that conforms to the power requirement specification based on the result (the necessity of work and application) calculated by the work indexing task 33. And based on the flowchart shown in FIG.

  First, a standard work period for the determined work is acquired (step S41). Specifically, as shown in FIG. 9, a standard work schedule table 341 in which a standard work schedule for each work content is stored is provided, and the standard work schedule of the corresponding work is acquired from the standard work schedule table 341. Next, a standard permission period for the determined application is acquired (step S42). Specifically, as shown in FIG. 10, a standard permission period table 342 storing a standard permission period (standard period until permission is granted) for each type of application or the like is provided, and this standard permission period table 342 is provided. Obtain a standard permission period for applicable applications from.

  Subsequently, it is determined whether or not the work determined by the work indexing task 33 and the application can proceed simultaneously (step S43). In other words, it is possible to prepare for work during the period until permission is granted, and determine whether the standard construction period and the standard permission period can overlap. This determination is made based on the contents of the work and the contents of the application. If simultaneous progress is possible, the longer period of the standard work period and standard permission period is set as the required period (step S44). If simultaneous progress is not possible, the standard work period and standard permission period are added. This period is set as a necessary period (step S45).

  Here, when a plurality of operations are determined in the first indexing task 331 as described above, the standard construction period for each work is acquired, and the longest standard construction period is determined depending on whether these operations can proceed simultaneously. Set the work period or add all the standard work periods to make the work period. Based on the construction period and the standard permission period, the necessary period is estimated in the same manner as described above (steps S44 and S45).

  Next, the operation of the period estimation system 1 having such a configuration will be described based on the timing chart shown in FIG.

  First, when the personal computer 2 accesses the electricity use application menu on the Web page of the estimation server 3 (step S51), an input screen for inputting power requirement specifications is displayed. Then, for example, when a construction company and an electric construction shop discuss and input a power requirement specification according to the input screen and perform a transmission operation (step S52), the input power requirement specification is transmitted to the estimation server 3 (step S53). ), The power requirement specification is stored in the memory by the application reception task 31 as described above.

  Next, the first indexing task 331 is activated in the estimation server 3 (step S54), and the work required to supply power that conforms to the power requirement specification is determined as described above. Further, the second indexing task 332 is activated (step S55), and it is determined what kind of application or notification is necessary or unnecessary for performing the work as described above. Subsequently, the estimation task 34 is activated (step S56), and a period (necessary period) required to supply power that conforms to the power requirement specification is estimated as described above. Then, the estimated necessary period is transmitted to the personal computer 2 together with the determined work and application (step S57).

  As described above, according to the period estimation system 1, the period required to supply power that conforms to the power requirement specification by inputting and transmitting the power requirement specification from the personal computer 2 of the electric construction shop is estimated server. 3 to the personal computer 2. For this reason, an electric construction shop, a construction company, or a customer (a purchaser of a house) can quickly and easily know the period until electricity can be used. As a result, it is possible to appropriately determine a plan for indoor wiring, a scheduled date for starting use of electricity, and the like.

  In addition, based on the planned location where power is used and the planned load, and the type, capacity, location, etc. of the power facility, the work to supply power, the necessity of application and notification of permission and notification, and the contents Determine the time required to supply power based on the result. In other words, since the necessary period is estimated in consideration of work such as outside line construction or application to the competent authority, an appropriate necessary period suitable for the demand of the customer is estimated. In addition, the work and application necessary for power supply are transmitted to the personal computer 2 together with the estimated required period, so how much work or application the electrical construction shop or construction company has for what kind of work or application. It is possible to know whether this period is required.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, the determination element in the work determination task 33 is not limited to the above determination elements (steps S1, S5, S9, etc.), and the work may be determined based on other determination elements / conditions. In the above embodiment, the power requirement specification and the estimation result are transmitted via the Internet NW, but the power requirement specification and the estimation result are notified by voice via the telephone network. It may be. Furthermore, the present invention can be applied not only to supplying power to a newly-built house, but also to adding a load accompanying a change in power usage contract or supplying temporary power.

  Incidentally, the following period estimation program (hereinafter referred to as “period estimation program”) required for power supply may be installed in a general-purpose computer. That is, the planned location where power is used, the planned load, etc. are used as power requirement specifications, and the computer is input as storage means (corresponding to the facility database 32) for storing facility information such as the type, capacity, and location of the power facility. Work required to supply power that conforms to the power requirement specification based on the power requirement specification and the facility information stored in the storage means, and whether or not an application for approval or notification is required to perform the task A work indexing means (corresponding to the work indexing task 33) for estimating the power, and an estimation means for estimating a time period required to supply power that conforms to the power requirement specification based on the result calculated by the work indexing means (Corresponding to the estimation task 34).
