Next, the operation of this embodiment will be described using a design process as an example from the input of the load specifications that have already been determined to the determination of the equipment configuration of the sewage treatment plant.

The table of each functional unit is shown in FIG.
Are registered in the external storage device 13 shown in FIG. The designer selects a load system unit (FIG. 4) from the registered functional units and calls it from the external storage device 13, and sets an attribute as a required specification of the called load system unit in an interactive format with the system. Is input by the input device 10 (FIG. 1). At this time, if the required specifications have not been determined, the system notifies the system that the designer has not been determined, and proposes initial values that are deemed appropriate by the system. The suggested initial values can be changed,
Temporarily set an appropriate value. The input attributes are sequentially stored in a predetermined area of the load unit table by the design specification input unit 1 (FIG. 1).

Next, when the load is classified and grouped by the design support system of this embodiment and the load configuration of the equipment is determined, the flow shifts to the processing flow shown in FIG.

That is, the table of the equipment system unit shown in FIG. 5 is called in accordance with the request of the designer (step 121), and first, the function attribute of the process 605 (FIG. 5) is set. Sewage treatment plant facilities can be broadly classified into three facilities: water treatment facilities, sludge treatment facilities, and associated facilities. Water treatment equipment further includes sedimentation basin equipment, sewage pump equipment, first sedimentation basin equipment, aeration tank equipment, final sedimentation basin equipment, and sterilization pond equipment. Sludge treatment equipment further includes thickening tank equipment, digestion tank equipment, and dewatering. The equipment equipment and the incinerator equipment, and the auxiliary equipment are further divided into deodorization equipment, blower equipment, and filtration pond equipment, respectively, and these are coded to become functional attributes of the process 605 (step 1).
22).

Next, the equipment name 606 (FIG. 5), which is the name of the equipment on the document, is entered (step 12).
3). Equipment corresponding to each process has a standard load configuration, which is registered in advance in the connection information storage unit 2a (FIG. 1). Based on the connection information registered in the connection information storage unit 2a, the connection relation setting unit 2b (FIG. 1) searches for a standard unit for each facility from the load system units generated as described above, The functional unit ID 501 (FIG. 4)
Are sequentially set as the function attributes of the connection unit ID 607 (FIG. 5) of the facility unit (step 124).
This connection relationship defines the relationship between the equipment and the equipment configuration load.
Until all the load system units are connected as facility configuration loads to the respective facility system units and the initial setting is completed (step 125), the above-mentioned processing 121 to processing 124 are repeated.

The display model organization unit 3a of FIG. 1 creates a facility load configuration table from the facility load configuration initially set as described above, and the model display unit 3b displays this on the display 9. The designer corrects the load configuration by moving the load between the facilities while referring to this.

Referring to FIG. 9, first, a designer issues a load movement calculation request (step 126). As a result, the model calculation request unit 4a
(FIG. 1) starts a movement calculation program of the model calculation control unit 4b (FIG. 1), and the started program requests designation of a movement target and a movement destination. According to this, the designer
For each facility, a load that needs to be moved from the displayed facility configuration loads is indicated on the display 9 (FIG. 1),
Next, when a destination facility is designated (step 12)
7), the connection relation updating unit 2c (FIG. 1) deletes the connection unit ID 607 set in the source facility unit (FIG. 5) by the instruction of the model calculation control unit 4b (FIG. 1), and Functional unit ID 50 of the load system unit (FIG. 4) that moves to the connection unit ID of the equipment system unit of FIG.
1 is set (step 128).

When the modification of the load configuration of the equipment is completed as described above (step 129), the procedure moves to the procedure shown in FIG. 10, and division is performed on the equipment in which loads having different electric attributes coexist. When the procedure of the equipment division is shown, the designer issues a request for the equipment division operation (step 130), whereby the model operation control unit 4b (FIG. 1) controls the load system unit (FIG. 4) for each equipment. The number of driving phases 502 and the driving voltage 503 are referred to. When load system units having different numbers of drive phases or drive voltages coexist in the same facility, the model calculation control unit 4b (FIG. 1) divides the facility system unit (FIG. 5) (step 131).

That is, first, an equipment system unit having the same process function attribute 605 (FIG. 5) as the equipment system unit to be divided is created, and then the original equipment system unit is used by using the connection relation updating unit 2c (FIG. 1). Unit (FIG. 5) connection unit ID 60
7, the functional unit ID 501 of the load system unit (FIG. 4) having a different number of drive phases and drive voltages is deleted, and this is set as the connection unit ID of the new equipment system unit. By this operation, the number of drive phases and drive voltages of the equipment constituent loads of each equipment are unified, and each is set as the number of equipment phases of equipment equipment units and the function attribute of the equipment voltage, thereby completing the equipment division calculation. The above is step 131. The above divisional operation is executed for all the equipment units (step 13).
2).

When the division operation of all the facilities is completed, a synthesis operation is performed between the facilities having a small facility configuration load or the like according to the judgment of the designer (step 133). When the designer issues a request for a synthesis operation after designating a plurality of facilities (step 134), the model operation control unit 4b (FIG. 1)
60 of the equipment phase of each equipment system unit (FIG. 5) in which
2 and the equipment voltage 603. Here, since the combination operation between the equipment units having at least one of the equipment phase number and the equipment voltage different from each other is not defined, it is checked whether or not the operation is possible (step 135). When the combining operation is possible, the model operation control unit 4b (FIG. 1) moves all the connection unit IDs of the other designated facility system units to one of the designated facility system units. When the movement is completed, the equipment unit of the movement source is deleted. The equipment name of the equipment unit after synthesis is not set. In addition, in the synthesis operation between the equipment units of different processes, the synthesis operation is completed with the process of the equipment unit after the synthesis not set yet (step 136). After the division operation and the combination operation are completed, the equipment name (606 in FIG. 5) is input to the equipment system unit for which the equipment name has not been set, the final load configuration of the equipment is determined, and The equipment configuration in the processing plant is determined (step 137).

Next, the operation of this embodiment will be described by taking as an example a design in which a power supply path (main line in a single-line diagram) to each facility is determined after the received voltage is determined.

When the equipment configuration in the sewage treatment plant is determined as described above, equipment units (FIG. 5) having the same number of equipment phases 602 and the same equipment voltage 603 are connected to one bus unit. That is, the connection relation setting unit 2b
(FIG. 1) calls up the table of the bus system unit (FIG. 6), and the number of equipment phases 602 and the equipment voltage 603 of the equipment system unit (FIG. 5) first referred to as the number of bus phases 702 of the table of the bus system unit. The function unit ID 601 of this equipment system unit is written to the bus unit 703 and the connection unit ID 705 of the bus system unit.

Next, if the number of equipment phases 602 and equipment voltage 603 of the referenced equipment system unit are equal to the number of bus phases 702 and bus voltage 703, respectively, the functional unit ID 601 of the equipment system unit is also changed to the connection unit ID 7 of the bus system unit.
Add to 05. When the number of equipment phases 602 and the number of bus phases 702 or the equipment voltage 603 and the bus voltage 703 are different, a table of the bus system unit is newly called, and the number of equipment phases 602 and the equipment voltage 603 are respectively changed to the number of bus phases 702 and the bus voltage. 703 is set, and the functional unit ID 601 of the facility system unit is written in the connection unit ID 705 to form a new bus system unit.

When the above operation is completed while referring to all the facilities, the total value of the facility capacity 604 of the facility system unit connected to the bus system unit is set to the bus capacity 704. At this point, the classification of the equipment by the required power source is completed, and the display model organizing unit 3 is created from the created functional unit.
a (FIG. 1) organizes a display model of the design plan at the abstract stage, and the model display unit 3b (FIG. 1) displays the display on the display 9 (FIG. 1) for the designer.

FIG. 11 shows an example of the display, in which virtual power supplies 32, 33, and 34, which are power supply sources set for convenience in the design process, are represented by hatched areas, and facilities which receive power supply therefrom. Represents an example of a facility group, which is a set of.

Table 30 shows the equipment configuration of the sewage treatment plant.
The correspondence between the circled numbers in the figure and the equipment is shown. Solid line 3
Reference numeral 5 represents a connection relationship between the virtual power supply and each facility. The entity of the virtual power source is a bus unit, and the virtual power sources 32, 33, and 34 represented by the shaded areas are one of the symbols for thinking of the designer.

When the display model of the design proposal is displayed in this manner, the designer can instruct the division of the equipment group from the viewpoint of the operation method of the equipment in the sewage treatment plant, the position of the equipment, and the like. Perform group division operation. Further, the bus capacity 704 of the bus system unit (FIG. 6) is displayed so that it is possible to know whether or not the capacity is concentrated on the bus. Concentration of capacity can be prevented. Here, FIG.
Assuming that the capacity is concentrated on the mother ship of the virtual power source 32 in 1, the operation of the division calculation of the equipment group will be described below.

When a facility to be divided is designated on the screen from the displayed facility group, the model calculation control unit 4b (FIG. 1) newly calls the bus unit table (FIG. 6), and the bus phase number 702, The bus voltage 703 is set. Then
The connection relation updating unit 2c (FIG. 1) deletes the functional unit ID 701 of the facility designated from the secondary connection ID 705 of the original bus system unit, and deletes the functional unit of the facility designated by the connection unit ID of the new bus system unit. Write the ID. The bus capacity of the new and old bus system units is reset, and the division of the equipment group is completed.

FIG. 12 shows a display model after the above divisional operation. The bus (group capacity 185.0 kW) of the virtual power supply 32 shown in FIG.
This shows that the bus is divided into a bus 2a and a bus of the virtual power supply 32b of 84.7 kW.

Next, the designer issues a transformer connection calculation request and creates a power distribution path from the power receiving portion to each facility. This is the original form of the trunk line in the single-line diagram, and is created by connecting the power receiving portion and each virtual power source with a transformer. The virtual power supply is a power supply required by the sewage treatment plant equipment, and is obtained by converting received power by a transformer. Hereinafter, an operation until a trunk line of a single-line diagram is created will be described.

First, based on the transformer connection calculation request, the model calculation control unit 4b (FIG. 1) changes the connection relation setting unit 2b.
Referring to the number of bus phases 702 of the bus system unit (FIG. 6), which is the entity of the virtual power supply (FIG. 1), the power supply is classified into two systems of a single-phase power supply and a three-phase power supply. Next, the bus voltage 703
, A virtual power supply having the highest voltage in each system is searched for, the connection relation setting unit 2b (FIG. 1) calls the transformer unit table (FIG. 8), and receives the allocated functional unit ID 901. The transformer is connected to the power receiving unit by writing to the secondary connection unit ID 806 of the system unit (FIG. 7). At this time, the model calculation control unit 4b
(FIG. 1) stores the number of receiving phases 802 and the receiving voltage 803, which are the functional attributes of the receiving unit (FIG. 7), in the number of primary phases 902 and the primary voltage 903 of the transformer unit (FIG. 8), respectively.

As a result of the search, when the virtual power supply having the highest voltage is found, the connection relation setting unit 2b (FIG. 1) sets the function unit ID 701 of the virtual power supply (bus system unit) to the connection of the transformer system unit (FIG. 8). Write to the unit ID 907 and connect the virtual power supply to the transformer. At this time, the model calculation control unit 4b (FIG. 1) converts the bus phase number 702 and the bus voltage 703 of the connected bus system unit (FIG. 6) to the secondary phase number 904 of the transformer system unit (FIG. 8). Stored at voltage 905. With the above operation, the virtual power supply is connected to the power receiving portion via the transformer.

Subsequently, the one having the highest voltage in each system is found from the unconnected virtual power supplies, and the secondary side of the virtual power supply connected to the power receiving part via the transformer is connected via the transformer. Connect. Similarly, when all the virtual power supplies are connected, a draft of a path for supplying power from the power receiving portion to all the virtual power supplies via the transformer is created.

FIG. 13 shows the design plan at this stage, which is displayed on the display 9 (FIG. 1) by the display model organization unit 3a (FIG. 1) composed of symbols and the model display unit 3b (FIG. 1). The power receiving portion 36 is a portion for receiving the power of the sewage treatment plant, and is represented as a virtual power source.
In the figure, reference numerals 40, 41, and 42 denote virtual power supplies, and 37, 3
Numerals 8 and 39 are symbols expressing transformers, respectively.

As described above, the power receiving portion 36 and each virtual power source 40
-42 via the transformers 37-39, a power supply path to each facility has been created from the connection relationship of the functional units. Here, FIG.
The virtual power supply 40 in the above has a bus phase number of 3 and a bus voltage of 400 V
And the bus power sources 32a, 32 in FIG.
13, the number of bus phases and the bus voltage 20 in FIG.
The 0V virtual power supply 41 is connected to the bus power supply 33 in FIG.
A virtual power supply 42 having a bus phase number of 1 and a bus voltage of 100 V in FIG. 13 corresponds to the bus power supply 34 in FIG. 12, respectively.
Then, the divided virtual power supplies 32a, 32 shown in FIG.
b is a virtual power source connected in parallel to the virtual power source 40 in FIG. 13, the virtual power source 33 shown in FIG. 12 is connected to the virtual power source 41 in FIG. 13, and the virtual power source 34 shown in FIG. 12 is connected to the virtual power source 42 in FIG. , Display model organization unit 3a
It is represented as shown in FIG. 14 by (FIG. 1). This satisfies the minimum specifications in the power system that converts the received power into the power required by each facility in the sewage treatment plant and satisfies the required specifications. The most abstract design proposals are being expressed.

When such an abstract design plan can be created, the design plan is embodied and detailed. In other words, the number of transformer banks for the trunk line in the single-line diagram is determined from the operation system such as the operation of each system of the equipment and the installation of the working / standby transformer in consideration of the reliability of power supply. The operation will be described by taking as an example a case where the designer determines that the number of banks of the transformer 37 in FIG. 14 needs to be changed in determining the operation method of the sewage treatment plant.

First, based on the display screen as shown in FIG. 14, the designer issues a request for divisional operation of the transformer via the model operation requesting unit 4a (FIG. 1). Subsequently, the model calculation control unit 4b (FIG. 1) displays on the menu the operation method that causes the change in the number of transformer banks. The designer selects a corresponding operation method from the displayed menu. Here, an example in which “operation by system” is selected will be described with reference to FIG.

When the menu is selected, the model calculation control section 4a (FIG. 1) prompts for a group of equipment to be operated for each system. In FIG. 14, two facilities are designated by designating virtual power supplies 32a and 32b. As a result, the transformer 37 whose number of banks needs to be changed can be specified, and one transformer unit (FIG. 8) having the same functional attribute as that of the transformer 37 is created. However, the functional unit ID 901 is different.

Next, a request is made to the connection relation updating section 2b (FIG. 1) to update the connection between the transformer 37 and the newly created transformer and the virtual power supplies 32a and 32b. The connection relation updating unit 2c (FIG. 1) adds the functional unit ID 901 of the newly created transformer system unit (FIG. 8) to the connection unit ID 806 of the power receiving system unit (FIG. 7), and connects to the power receiving unit. Next, the function unit ID of the virtual power supply 32b is calculated from the connection unit ID of the function unit of the transformer 37.
And disconnect these connections. Instead, the functional unit ID of the virtual power supply 32b is written and connected to the connection unit ID of the functional unit of the new transformer.

Thus, the process of changing the number of banks of the transformer 37 is completed.

When the design target model of FIG. 15 is converted into a single-line diagram, as shown in FIG. 16, the virtual power sources 32a and 32b become bus lines, and the virtual power sources 33 and 34 have no corresponding drawing symbol. It is not displayed and becomes the main line of the single-line diagram.

As described above, according to this embodiment, the design specification is detailed for each function, and the abstraction of the power system called the virtual power supply is performed, so that the design plan in the middle of the design can be easily grasped. This allows the designer to organize his thoughts and proceed with the design while making accurate decisions. Furthermore, since the connection relationship between the functional units representing the electrical connection is set with reference to the electrical attributes of each functional unit, it is possible to avoid creating a design plan due to incorrect connection. Further, according to this embodiment, since there is no restriction on the design procedure, it is possible to perform design utilizing the ability of the designer.
