Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric system diagram management / design support device for unifying electric system diagram, electric facility information, and management / design support information to support electric system diagram management / design work. is there.

[0002]

2. Description of the Related Art Conventionally, electric system diagram management and design work involves drawing information, which is system diagram information, and management and design information necessary for management design of electrical equipment (for example, specifications such as rated capacity, allowable load factor, and line voltage). (Electrical equipment information such as standards) is managed as a completely separate database. For example, in management design work in equipment expansion, equipment should be added to system diagram information by hand, and calculation for management design is managed. Databases prepared individually by reference to design information based on predetermined arithmetic expressions, or as shown in FIG. 5, separately prepared by a computer 2 to which an input / output device 1 is connected and which has predetermined calculation logic. The information required for calculation was input from 3 and 4.

[0003] Support functions for supporting the electric system diagram management design work include capacity calculation processing, voltage drop rate calculation processing, and short-circuit current calculation processing. For example, when an electric motor 21 is added to the electric system diagram shown in FIG. 2 as an additional facility, the capacity calculation process will be described as an example. A series of various types from the added electric motor to the transformer (Tr100) 22 located upstream. We will compare the allowable capacity of electrical equipment with the load capacity including the motor. The capacity calculation formula is based on the following calculation formula, which is different for each electric equipment.

Load capacity (A) = expanded equipment apparent power (KV
A) × (Voltage (KV) × √3 Allowable load current (A) = Rated current (A) × Allowable load factor Load capacity (KVA) = Actual load capacity (KVA) + Apparent power of additional equipment (KVA) Allowable load capacity (KVA) = rated load capacity (KVA) × allowable load factor

Depending on the target equipment, there are cases where the current value is compared and where the capacity value is compared. Further, when the load value exceeds the allowable value, various situations were judged and processed based on the experience and intuition of the designer.

[0006]

Since the conventional electric system diagram management design support device is configured as described above, for example, in the case of FIG.
Various cables (CA016) 23, (CA001)
24, CBS (DS010) 25, VCB (VCB0
1) 26, (VCB02) 27, transformer (Tr100)
There is a lot of equipment such as No. 22, and all load values and allowable values must be calculated for each of them, and these must be compared and examined, which requires a great deal of time for electrical system diagram management and design work. was there.

On the other hand, when a computer system provided with a calculation logic is used without using manual calculation, it is necessary to input various data required for the calculation, and there is a problem that a large amount of time is required for the input time. It was

Further, as a result of comparing the calculated values, if the load value exceeds the allowable value, it is necessary to obtain the cooperation of a skilled engineer to deal with it, and only a specific person can design, or
There is also a problem that we can not respond if an emergency is required,
Further, there is a problem that quality improvement cannot be expected due to manual work.

The present invention has been made in order to solve the above-mentioned problems, and even an unskilled person can quickly perform the electrical system diagram management design work and can improve the quality of the electrical system diagram management design support device. The purpose is to get.
