Description

  The present invention relates to a power supply panel design support technology that supports power supply cable connection design for creating connection information between a power supply panel in a plant or the like and a power supply cable of a power supply target device such as a power machine.

  Usually, a power supply panel for supplying power to various electric devices including a power machine in the plant is installed in a monitoring center or an electrical room of a plant such as a factory. That is, power is supplied from the power supply panel to the electric motor or the static load electric device via the power supply cable. At this time, the number of electrical devices connected to the power supply panel, that is, the power supply cables is very large, and in a large thermal power plant or the like, the number may be several thousand. In addition, the type and size of the power supply cable vary depending on the capacity of the electric device, the distance to the installation position, and the like. Furthermore, the power supply panel is provided with various types of circuit breakers (circuit breakers), magnetic contactors (contactors), overload relays (overload relays) and the like to which the power supply cable is connected.

  Therefore, for such a power panel, the secondary of the power supply cable and the circuit breaker, magnetic contactor, overload relay, etc. (hereinafter collectively referred to as “power connection / disconnection unit”) to which the power supply cable is connected. The design work for creating connection information with the side terminals becomes complicated and requires considerable design experience. Therefore, in other words, it can be said that the design work is prone to human error. If a design error occurs and is overlooked, a serious situation such as the inability to connect the power supply cable will occur at the stage of on-site assembly work of the power supply panel.

  Patent Document 1 discloses an example of a design support apparatus (method) that supports connection design of cables for connecting a plurality of power supply panels by a computer.

JP 2008-129848 A

  However, in the design support apparatus for connection design between power supply panels described in Patent Document 1, cable connection via a terminal block is assumed. Therefore, in the cable connection design, it is not necessary to consider the diversity of the power connection / disconnection unit such as the circuit breaker, the magnetic contactor, and the overload relay. Therefore, although the method for supporting the cable connection is simplified, the power supply panel is increased in size by the amount of the terminal block, and the manufacturing cost is increased.

  In addition, when connecting the power supply cable directly to the secondary terminal of the power connection / disconnection unit without providing a terminal block, there are many types of power connection / disconnection units, and the cable size that can be connected depending on the model Due to the differences in power supply and the size of the power supply cable of the power supply target device, manual creation of connection information is not efficient as described above, and mistakes also occur. Cheap.

  In view of these problems of the prior art, the object of the present invention is to provide a power supply cable connection design that creates connection information between a secondary terminal of a power connection / disconnection unit provided on a power supply panel and a power supply cable of a power supply target device. It is to provide a power supply panel design support technology capable of improving efficiency.

  In order to achieve the object of the present invention, in the power supply panel design support apparatus of the present invention, for each power connection / disconnection unit provided on the power supply panel in the storage device, the power connection / disconnection unit is installed on the power supply panel. The power panel connecting / disconnecting unit information in which the position number and the type and model of the power connecting / disconnecting unit provided at the installation position are associated with each other, and each power connecting / disconnecting unit provided on the power supply panel For each power supply target device connected via the power supply cable, the identification number of the power supply target device, the type of the power connection / disconnection unit to which the power supply target device should be connected, and the power supply cable specified for the power supply target device Connected device power supply cable information that holds the cable size in association with each other, and the type and model of the power connection / disconnection unit are connected to the power connection / disconnection unit. And allowable cable size information holding the allowable cable size of the power supply cable, the stored beforehand.

  Then, the CPU refers to the allowable cable size information, acquires the allowable cable size corresponding to the type and model of each power connection / disconnection unit stored in the power panel connection / disconnection unit information, and determines the acquired allowable cable size. The processing to be added to the power panel connecting / disconnecting unit information, the processing for sorting the power panel connecting / disconnecting unit information and the connected device power supply cable information according to the type, and each included in the power panel connecting / disconnecting unit information for each sorted type For a power connection / disconnection unit, a power supply target device that matches the allowable cable size of the power connection / disconnection unit is selected from the power supply target devices included in the sorted connection device power supply cable information, and the selected power supply target device is selected as its power source.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram illustrating an example of a schematic configuration of a power supply panel to be designed by a power supply panel design support apparatus according to an embodiment of the present invention. As shown in FIG. 1, the power supply panel 11 is provided with a plurality of power connection / disconnection units 12, and primary terminals (not shown) of the respective power connection / disconnection units 12 are connected to the main power supply 10, The secondary terminal 13 is connected to the power supply target device 15 via the power supply cable 14.

  Here, the power connection / disconnection unit 12 is, for example, a circuit breaker, an electromagnetic contactor, an overload relay, or the like, and is a device that controls the power supply interruption or connection to the power supply target device 15. In FIG. 1, only one secondary terminal 13 of the power connection / disconnection unit 12 is illustrated, but normally, two for a single phase and three for a three phase depending on the number of phases of the main power supply 10. One is provided.

  Various devices such as power machines, compressors, and indoor lighting can be assumed as the power supply target device 15, and the type of the power connection / disconnection unit 12 is also specified according to the type of the power supply target device 15. There are many. For example, in the case of an electric device constituted by an electric motor such as a power machine or a compressor, it is connected to an electromagnetic contactor, and in the case of an electric device having a static load such as room lighting, it is connected to a circuit breaker.

  FIG. 2 is a diagram showing an example of the configuration of the power panel design support apparatus according to the embodiment of the present invention. As shown in FIG. 2, the power supply panel design support apparatus 2 is configured by a general computer, and includes a CPU (Central Processing Unit) 20, a storage device 25, a display device 29, and the like. The power supply panel design support apparatus 2 is communicably connected to a database server apparatus 3 including a power supply panel facility DB (DB is an abbreviation of database) 31 and an allowable cable size DB 32 via a communication network 4. Yes.

  Here, the power panel equipment DB 31 stores information on various specifications for the power panel identified by the power panel name. Here, as the specification information, information about the power connection / disconnection unit 12 installed in the power supply panel (information such as the installation position on the power supply panel, the type and model of the power connection / disconnection unit 12 installed) Is included. The type of the power connection / disconnection unit 12 is information indicating whether the power connection / disconnection unit 12 is classified as a circuit breaker, an electromagnetic contactor, an overload relay, or the like, and the model is the power connection / disconnection unit 12 The model name given by the manufacturer.

  Further, the allowable cable size DB 32 stores the maximum value and the minimum value of the cable size that can be connected to the secondary terminal 13 of the power connection / disconnection unit 12 for each model of the power connection / disconnection unit 12. The configuration of the allowable cable size DB 32 will be described separately with reference to the drawings.

  When the power supply panel design support device 2 receives an input of a power supply panel name of the power supply panel 11 to be designed, and further receives an input of information about the power supply cable 14 of the power supply target device 15 to be connected to the power supply panel 11, With reference to the power supply panel facility DB 31 and the allowable cable size DB 32, the power supply of the power supply target device 15 to be connected to each of the power connection / disconnection units 12 installed in the power supply panel 11 specified by the received power supply panel name The cable 14 is determined.

  In order to realize such a function of the power panel design support device 2, the storage device 25 stores information such as the power panel connection / disconnection unit information 26, the connected device power supply cable information 27, the allowable cable size information 28, and the like. The CPU 20 is provided with functional blocks such as an allowable cable size addition processing unit 21, a device power supply cable allocation processing unit 22, and a power supply cable connection information display processing unit 23. Note that the functions of these functional blocks 21, 22, and 23 are realized by the CPU 20 executing a predetermined program stored in the storage device 25, as will be described with reference to FIG.

  Next, with reference to FIG. 3 to FIG. 7, processing contents of the power panel design support process executed in the power panel design support apparatus 2 and the configuration of data used in the process will be described. Here, FIG. 3 is a diagram showing an example of a processing flow of the power panel design support process executed in the power panel design support apparatus 2 according to the embodiment of the present invention, and FIG. 4 is a power panel connection / disconnection unit. It is the figure which showed the example of the structure of the information 26 and the connection apparatus electric power feeding cable information 27. FIG.

  First, the CPU 20 receives an input of a power supply panel name and connected device power supply cable information 27 input by a design worker via an input device such as a keyboard (step S11). Here, the power board name is information for designating the power board 11 to be designed. The connected device power supply cable information 27 is information for specifying the power supply target device 15 in the plant to be connected to the power supply panel 11, and the configuration thereof will be described later.

  Then, CPU20 acquires the power supply panel connection / disconnection unit information 26 about the power supply panel 11 designated by the said power supply panel name from power supply panel installation DB31 (step S12). Here, the power panel connection / disconnection unit information 26 holds information about the power connection / disconnection unit 12 installed in the power supply panel 11. That is, as shown in FIG. 4A, the power panel connection / disconnection unit information 26 includes information such as a power panel name, power panel connection / disconnection unit information, connected device information, and countermeasure information.

  The power panel connection / disconnection unit information is information acquired from the power supply panel facility DB 31, and more specifically, for each power connection / disconnection unit 12 installed in the power supply panel 11 specified in the power supply panel name column. It includes information such as unit number, type, and model. Here, the unit number is information indicating the installation position of the power connection / disconnection unit 12 on the power supply panel 11, and the type is information for classifying the power connection / disconnection unit 12 (breaker, electromagnetic contactor, excess contactor). The information indicating the load relay and the like) and the model are manufacturer-provided model names of the power connection / disconnection unit 12.

  The connected device information is information on the name and identification number of the power supply target device 15 connected to the secondary terminal 13 of the power connection / disconnection unit 12 via the power supply cable 14. This identification number is a number that can uniquely identify the power supply target device 15 in the plant. Therefore, a unique power supply target device 15 is associated with the power connection / disconnection unit 12. However, since this connected device information is not yet determined at the stage of step S12, this field is blank.

  The countermeasure information is information that is set when there is no power connection / disconnection unit 12 that can be connected to the power supply target device 15 to be connected. The countermeasure information will be described in detail later, but in this embodiment, only countermeasure information for adding a terminal block is presented. In the step S12, the countermeasure information column is also blank.

  Next, as illustrated in FIG. 4B, the connection device power supply cable information 27 includes information such as connection device information, a connection / disconnection unit type, and a cable size. The connected device power supply cable information 27 is basically information input by the design operator, and the information specifies the power supply target device 15 in the plant to be connected to the power supply panel 11. The cable size of the power feeding cable 14 used for the connection is specified.

  Here, the connection device information of the connection device power supply cable information 27 includes a name and an identification number, and the power supply target device 15 is designated by the identification number. The connection / disconnection unit type is information for specifying the type of the power connection / disconnection unit 12 to which the power supply target device 15 specified by the identification number is to be connected. The cable size is information indicating the diameter (thickness) of the power supply cable 14 of the power supply target device 15 specified by the identification number.

  Since there are many power supply target devices 15, the design operator does not input the connection device power supply cable information 27 from the keyboard or the like in the process of step S 11. The power supply cable information 27 may be created in advance as a list in a tabular format, and in the process of step S11, the CPU 20 may read the list.

  Referring to FIG. 3 again, as processing subsequent to step S12, the CPU 20 refers to the allowable cable size information 28 and adds the allowable cable size to the power supply panel connecting / disconnecting unit information 26 (step S13).

  Here, FIG. 5A is a diagram showing an example of the configuration of the allowable cable size information 28. As shown in FIG. 5A, the allowable cable size information 28 is information in which the allowable cable size and the type of the power connection / disconnection unit 12 are associated with the model of the power connection / disconnection unit 12. In other words, the data of each row stored in the allowable cable size information 28 includes the type of the power connection / disconnection unit 12 and the secondary terminal of the power connection / disconnection unit 12 of the type specified in the model column. 13 is a data that defines the range of the cable size of the power feeding cable 14 that can be connected to 13.

  These data are data specific to the model of the power connection / disconnection unit 12, and such data is usually described in the catalog or data sheet of the power connection / disconnection unit 12 of the model. Therefore, in the present embodiment, the design operator reads the data of the allowable cable size from the catalog or the data sheet for the necessary type of power connection / disconnection unit 12, and registers it in the allowable cable size DB 32 on the database server device 3. Keep it. Then, before step S12 is executed, all or a part of the allowable cable size DB 32 is downloaded to the power supply panel design support apparatus 2 and used as the allowable cable size information 28.

  In the allowable cable size DB 32, re-registration is not necessary for the data of the allowable cable size of the power connection / disconnection unit 12 once registered. The design operator only needs to read the data of the allowable cable size from the catalog or the data sheet for only the unregistered type of power connection / disconnection unit 12 with reference to the allowable cable size DB 32. Therefore, in this embodiment, a plurality of design workers can avoid reading the data of the allowable cable size from the catalog or data sheet of the same type of power connection / disconnection unit 12 redundantly.

  FIG. 5B is a diagram showing an example of the configuration of the power panel connection / disconnection unit information 26 to which the allowable cable size information is added by the execution of step S13. According to FIG.5 (b), the structure of the power supply panel connection / disconnection unit information 26 adds the data of allowable cable size to the structure of the power supply panel connection / disconnection unit information 26 shown to Fig.4 (a). I understand.

  Referring to FIG. 3 again, as processing subsequent to step S13, the CPU 20 sorts the power panel connection / disconnection unit information 26 and the connected device power supply cable information 27 for each type of the power connection / disconnection unit 12 (step S14). Then, a loop process for executing up to step S21 is started for each type (step S15).

  In the loop processing, the CPU 20 first refers to the sorted power panel connection / disconnection unit information 26, and sets a cable size suitable for the allowable cable size of the power connection / disconnection unit 12 for each power connection / disconnection unit 12. The power supply target device 15 (hereinafter simply referred to as “device” when it is clear that it is the power supply target device 15) is selected from the devices included in the connected device power supply cable information 27 after sorting. The selected device is assigned to the connection target device of the power connection / disconnection unit 12 (step S16).

  FIG. 6A shows the four power connection / disconnection units 12 included in the power supply panel connection / disconnection unit information 26 after sorting the power supply panel connection / disconnection unit information 26 of FIG. 5B by the type “C1”. It is the figure which showed the example of the power supply panel connection / disconnection unit information 26 to which the electric power feeding object apparatus 15 contained in the connection apparatus electric power feeding cable information 27 after similarly sorting by classification "C1" was allocated. FIG. 6B is an example of the connected device power supply cable information 27 in which the connected device power supply cable information 27 of FIG. 4B is sorted by the type “C1”.

  In the example of the power panel connection / disconnection unit information 26 in FIG. 6A, the allowable cable size of the power connection / disconnection unit 12 having the unit number “1” is “20 to 50”. At this time, referring to the connected device power supply cable information 27, there is a device having an identification number “KKS106” as the power supply target device 15 that matches the allowable cable size.

  Therefore, in step S16, the device having the identification number “KKS106” is assigned to the power connection / disconnection unit 12 having the unit number “1”. Similarly, a device having an identification number “KKS208” is assigned to the power connection / disconnection unit 12 having the unit number “2”, and an identification number “KKS005” is assigned to the power connection / disconnection unit 12 having the unit number “6”. Is assigned. On the other hand, in step S16, the device having the identification number “KKS177” is in an unallocated state because there is no suitable power connection / disconnection unit 12.

  Referring to FIG. 3 again, if there is an unallocated device included in the sorted connected device power supply cable information 27 in the process of step S16 (Yes in step S17), the CPU 20 further cancels the process. It is determined whether or not the assigned device can be handled by adding a terminal block (step S18). A description of the terminal block addition will be given later.

  As a result of the determination, if it is not possible to respond by adding a terminal block (No in step S18), as shown in FIG. Is set (step S19). Further, as shown in FIG. 7A, when the terminal block can be added (Yes in step S18), the CPU 20 adds “terminal block addition” to the corresponding information column of the power panel connection / disconnection unit information 26. Is set (step S20).

  Next, when there is no unallocated device in the process of step S16 (No in step S17), or when step S19 or step S20 is executed, the loop process started in step S15 is repeated (step S21). . Note that the loop processing of steps S15 to S21 is repeatedly executed for all the types of the power connection / disconnection unit 12 set in advance, and when the loop processing for all the types is completed, the loop processing is obtained by the processing so far. The power board connection / disconnection unit information 26 is displayed on the display device (step S22).

  In the case of FIG. 6A, since a terminal block cannot be added to an unallocated device having the identification number “KKS177”, data “impossible to handle” is set in the countermeasure information column.

  FIG. 7 is a diagram showing an example of power panel connection / disconnection unit information when a part of the power connection / disconnection unit information of FIG. In the example of FIG. 7A, the power supply panel 11 is provided with five power connection / disconnection units 12, and the power connection / disconnection units 12 with the unit numbers “5” and “7” include the power supply target device 15. Is not connected. On the other hand, the power supply cable 14 of the power supply target device 15 with the identification number “KKS177” cannot be directly connected to any of the power connection / disconnection units 12 of the unit numbers “5” and “7” because the cable size is large. .

  Therefore, in such a case, a terminal block 16 is provided in the power supply panel 11 as shown in FIG. The terminal block 16 is provided with a terminal to which the power supply cable 14 of the power supply target device 15 whose identification number is “KKS177” can be connected. Further, the other two terminals on the terminal block 16 electrically connected to this terminal are connected to the power connection / disconnection unit 12 having unit numbers “5” and “7”, respectively.

  That is, in the example of FIG. 7B, the power supply cable 14 of the power supply target device 15 with the identification number “KKS177” is once connected to the terminal of the terminal block 16, and the unit number “5” and It is connected to the power connection / disconnection unit 12 of “7”. Accordingly, in this case, the power supply connection / disconnection to the power supply target device 15 having the identification number “KKS177” is performed by the two power connection / disconnection units 12.

  In this way, in the example of FIG. 7A, since the connection to the device having the identification number “KKS177” which is the unallocated power supply target device 15 can be supported by the addition of the terminal block 16, the power supply panel disconnection is possible. In the countermeasure information column of the device whose identification number of the contact unit information 26 is “KKS177”, data of “terminal block addition” is set.

  When there is no power supply target device 15 to be connected as in the power connection / disconnection unit 12 with the unit number “5” in FIG. 6A, the countermeasure information column includes, for example, “empty”. Data may be set. Further, when connected to the power supply target device 15 via the terminal block 16, like the power connection / disconnection unit 12 of the unit numbers “5” and “7” in FIG. For example, data of “terminal block connection” may be set.

  The power panel connection / disconnection unit information 26 generated as described above is displayed on the display device or the like in the process of step S22, but the process may be a process of printing on paper by a printer. The design operator can obtain information on which power supply connection / disconnection unit 12 should be connected to the secondary terminal 13 of the power supply connection / disconnection unit 12 based on the display or the printed result. When there is no power connection / disconnection unit 12 that matches the cable size of the power supply cable 14 of the power supply target device 15, “not compatible” is displayed. When the terminal block 16 is provided, Since “terminal block addition” or the like is displayed, the design worker can quickly start taking countermeasures such as reviewing the specifications of the power supply panel 11 or performing additional design of the terminal block 16.

  The power board 11 of the present embodiment is based on the premise that the terminal block 16 is not provided in principle. Therefore, the design operator determines whether or not the terminal block can be actually added. It is decided after discussion with the user of the power supply and the manufacturer (vendor) of the power supply panel 11.

  As described above, according to the present embodiment, the design worker can avoid duplication registration of allowable cable size information as work, and the connected device for the power supply target device 15 connected to the power supply panel 11 to be designed. Since the power supply panel connection / disconnection unit information 26 including the connection information between the power connection / disconnection unit 12 and the power supply target device 15 can be obtained simply by creating the power supply cable information 27, the efficiency of the power supply panel design is improved. In addition, when there is a power supply target device 15 that cannot be connected to the power connection / disconnection unit 12 of the power supply panel 11, countermeasure information such as “cannot be handled” or “additional terminal block” is displayed on the display device 29. The design worker can take some measures before reaching the field work. Therefore, it is avoided that the power supply cable 14 cannot be connected to the power supply panel 11 in the field work.

  Further, when the power supply panel design support apparatus 2 of the present embodiment is used, what should be done by the design worker in the design work of the connection information with the power supply target device 15 in the power supply panel 2, that is, what kind of design worker It becomes clear whether information should be input. Therefore, the design work can be performed even by a design worker who is not experienced.
