Meanwhile, the output unit 180 is composed of a display device or a printer to display or print the technical specifications.

An example of the operation of the apparatus for operating a smart grid communication network according to the present invention configured as described above is as follows.

First, the input unit 110 receives consumer information indicating that it is a 500-unit hallway apartment in a city from a user, and provides it to the consumer classification index determining unit 120 .

Then, since the consumer classification indicator determining unit 120 is an urban material and is an apartment with a scale of 500 households, it is classified as an urban type and set to 0, and since it is a hallway apartment with a scale of 500 households, it is classified as a dense type and set as Mil 2, and since it is an apartment, It is classified as an aggregate type in which households are collectively distributed and set as type 1, and since it is composed of underground distribution lines, the power grid is classified as an underground line type and set as line 1.

In addition, the applicable architecture selection unit 130 selects an appropriate architecture by referring to Table 1 based on the geo-mild 2-type 1-line 1 standard selected by the consumer classification index determination unit 120, and 1, 2, 4, and 5 are possible. do.

When several architectures are selected in this way, the application architecture selection unit 130 selects the highest architecture 1 as the final architecture.

Since the apartment is a hallway type apartment, and smart meters for each household are concentrated in one distribution board on each floor, it is appropriate to select a method of having LNAP for each floor and NNAP for each apartment building, and architecture 1 selection is reasonable.

When 1 is selected as the final architecture, the application architecture selection unit 130 selects AMI headend, NNAP, LNAP, and smart meter as components, and selects R _NH , R _LN , and R _ML as communication interface reference points.

Meanwhile, the input unit 110 receives communication configuration requirements from the user and provides them to the communication configuration indicator determination unit 140 .

At this time, as communication configuration requirements input through the input unit 110, for example, application requirements are meter reading and additional services, and the coverage range is R _NH greater than 50 m, R _LN less than 50 m, and R _ML less than 10 m. .

Also, the communication performance requirements are that R _NH is greater than 10 Mbps, R _LN is less than 10 Mbps, and R _ML is less than 1 Mbps in consideration of additional services.

In addition, the requirement of the hybrid configuration method is single communication for each reference point even if different communication is used according to the characteristics of each reference point.

Next, the LOS/NLOS classification requirements require R _NH to be LOS, R _LN to be NLOS, and R _ML to be LOS according to the selection of wired/wireless communication for each reference point.

Meanwhile, regarding the requirement for the number of nodes, R _NH is more than 100, R _LN is 20 or less, and R _ML is 20 or less, considering the number of lower nodes viewed from the top of each reference point.

In addition, according to the power line classification requirements, R _NH , R _LN , and R _ML are underground distribution lines or underground service lines according to the power line type for each reference point.

Next, since sufficient service support is available for the use of repeaters, repeaters are not used for all reference points.

And, wired/wireless communication classification requirements are wired based on selection of wired/wireless communication for each reference point.

Upon receipt of such a requirement, the communication configuration indicator determination unit 140 sets the application requirement to meter reading + additional service: A1 at all reference points in consideration of the additional service, and the coverage range is determined according to the distribution characteristics of the components. R _NH : C2, R _LN : C1, R _ML : C0 are set, and communication performance requirements are set to R _NH : D3, R _LN : D2, R _ML : D1 considering the support of additional services.

In addition, the communication configuration indicator determination unit 140 sets single communication R _NH : H0, R _LN : H0, R _ML : H0 for each reference point even if different communication is used according to the characteristics of each reference point as a mixed and complex configuration method, , LOS/NLOS classification is set as R _NH : L0, R _LN : L1, R _ML : L0 according to the selection of wired/wireless communication for each reference point, and the number of nodes is determined by considering the number of lower nodes viewed from the upper level for each reference point. Set as R _NH : N3, R _LN : N1, R _ML : N1.

In addition, the communication configuration indicator determination unit 140 sets the power line classification to R _NH : P1, R _LN : P1, and R _ML : P1 according to the power line type for each reference point, and whether or not a repeater is used is sufficient to support all reference points. R0 is set for the point, and wired/wireless communication classification is set as R _NH : W0, R _LN : W0, R _ML : W0 according to the selection of wired/wireless communication for each reference point.

Meanwhile, the communication technology selection unit 150 reviews possible communication technologies for each reference point according to the result of the communication configuration index determination unit 140, and determines with reference to Table 3. R _NH is an optical subscriber network, and R _LN is High-speed PLC R _ML configures serial communication.

Finally, the technical specification derivation unit 160 derives and provides the technical specifications shown in Table 4, and the output unit 180 provides them through a display device or by printing them.

Of course, the next higher level architecture may be selected as the final architecture, or the lower level architecture may be selected as the final architecture.

If an architecture is selected through the application architecture selection unit through this process, a communication interface reference point is checked in the corresponding architecture (S40).

Next, the input unit receives communication configuration conditions from the user and provides the received communication configuration conditions to the communication configuration index determination unit (S50).

Accordingly, the communication configuration indicator determining unit receives communication configuration conditions through the input unit, determines and provides communication configuration indicators according to the input communication configuration conditions (S60). At this time, the communication configuration indicator determination unit refers to the communication configuration indicator table in Table 2.

Next, the communication technology selection unit selects an appropriate communication technology for each communication reference point of the architecture using the communication configuration index determined by the communication configuration indicator determination unit (S70).

To this end, the communication technology selection unit performs this by referring to the communication configuration index supportability table for each communication technology as shown in Table 3 stored in the storage unit.

The communication technology selection unit sets the allocation value to 2 for high, medium to 1, and low to 0 in the communication configuration indicator supportability table for each communication technology, and obtains result values for each communication technology for all corresponding communication configuration indicators Select the communication method with the highest result value.

Of course, the communication technology selector may select a communication technology in consideration of cost, complexity, ease of operation and management, and the like.

On the other hand, the technical specification derivation unit determines the consumer type determined by the consumer classification index determination unit, the architecture structure selected by the applied architecture selection unit and the configuration of components and communication interface reference points based on it, and the reference point format in the communication configuration index determination unit. And, technical specifications including the reference point communication technology selected by the communication technology selection unit are derived and provided (S80).

On the other hand, the output unit is composed of a display device or a printer to display or print the technical specifications (S90).
