1 and 2, the distribution-AMI linkage gateway 100 according to an embodiment of the present invention provides the transmission and reception data transmitted from the smart distribution system 200 and the AMI system 300 in association with each other. . In the embodiment of the present invention, it is shown that only the AMI system 300 is connected to the distribution-AMI linkage gateway 100, but the present invention is not limited thereto, and a plurality of AMI systems may be connected.

The gateway for linking the smart power distribution system and the AMI system (hereinafter, referred to as a "distribution-AMI linkage gateway") 100 includes an AMI linkage processing unit 110, a power distribution linkage processing unit 120, and a shared memory unit 130. .

The AMI linkage processor 110 is connected to the AMI system 300 to transmit and receive data (hereinafter, referred to as "AMI data") of the AMI system 300.

The distribution linkage processing unit 120 is connected to the smart distribution system 200 to transmit and receive smart distribution system data (hereinafter, referred to as "distribution data"). The power distribution connection processor 120 connects to the communication network of the smart power distribution system 200 using a communication function used by the smart power distribution system 200. In this case, as a communication network of the smart power distribution system 200, mainly a DNP (Distributed Network Protocol) or IEC (International Electrotechnical Commission) 60870 protocol is widely used. Recently, the communication between the distribution operation system and the distributor is performed by applying the IEC 61850 protocol to operate a smart distribution system. Accordingly, the power distribution linkage processing unit 120 is implemented to provide IEC 61850 functions to be connected to the smart power distribution system 200, and uses a communication protocol defined for use in IEC 61850 to provide one smart power distribution system 200. Connected to the node.

The shared memory unit 130 stores the data of the AMI system 300 transferred from the AMI linkage processing unit 110 so that the smart distribution system 200 can obtain the data. The shared memory unit 120 stores the data of the smart power distribution system 200 transmitted from the power distribution coordination processor 120 to be acquired by the AMI system 300.

Unlike the general communication protocol, the IEC 61850 protocol used in the embodiment of the present invention does not merely define a method of transmitting and receiving data, but further divides the apparatus and system to be communicated into independent functional units, and these functional units communicate. By defining a data model centered on the information to send and receive to and from the outside, the values of data elements are transmitted and received. In other words, applying the IEC 61850 protocol to a system applies a functional data model to each device constituting the system and sends and receives data based on the data model. When linking a system that does not use the IEC 61850 protocol with a system that uses the IEC 61850 protocol, the device responsible for the association configures the IEC 61850 data model for each unit function of the equipment in the system that does not use the IEC 61850 protocol. The data obtained from the system not using the IEC 61850 protocol should be mapped to the data model so that the data can be accessed from the system using the IEC 61850 protocol.

For example, when the distribution linkage processing unit 120 provides the IEC 61850 protocol, the distribution linkage processing unit 120 provides each AMI device that provides AMI data to provide a function of converting the AMI data to conform to the IEC 61850 protocol. It has the IEC 61850 data model for, and performs the process of mapping the AMI data to the appropriate model among the AMI device-specific data models. That is, the distribution linkage processor 120 includes an IEC 61850 data model defined for the component devices of the AMI system 300.

Since the smart meter is included as a device having a lot of data to be transmitted to the higher constituent AMI device 330 of the AMI system 300, the power distribution linkage processing unit 120 has built-in IEC 61850 data model for each unit function of the smart meter and smart The data of the meter is transmitted to the smart power distribution system 200 in correspondence with the data model. In this case, the unit function of the smart meter includes a configuration function, a meter measurement function and a load profile function. An example of a data model for the configuration function is shown in Table 1. An example of the data model for the meter measurement function is shown in Table 2, and an example of the data model for the function of the load profile is shown in Table 3.

In addition, the components of the AMI system 300 may include a power generation system (not shown) using new energy such as solar / wind power / fuel cell, or may include an energy storage system (not shown). 120 may configure an appropriate IEC 61850 data model for each of the power generation system and the energy storage system, and transfer the AMI data to the smart power distribution system 200 in correspondence with the IEC 61850 data model.

The AMI processing processor 111 provides a communication function with the data collection device 310 of the AMI system 300. When the AMI processing processor 111 receives a data request message for requesting data from the AMI system 300, the AMI processing processor 111 uses the data stored in accordance with a list stored in advance in the AMI processing memory 112 to transmit data for the data request message. A response message is generated and delivered to the AMI system 300. When the data write message is transmitted from the AMI system 300, the AMI processing processor 111 stores the data transmitted from the AMI system 300 in the form of a predetermined list in the AMI processing memory 112.

In addition, the AMI processing processor 111 reads data to be delivered to the smart power distribution system 200 from the AMI processing memory 112 and delivers the data to the shared memory unit 130 to store the data. In addition, the AMI processing processor 111 sets a flag indicating that there is an interrupt signal or data so that the smart power distribution system 200 receives the corresponding data. The AMI processing processor 111 reads the distribution data from the shared memory unit 130 and stores the distribution data in the AMI processing memory 112 when the flag indicating that there is an interrupt signal or data is set from the smart power distribution system 200. do.

Using the data, a data response message for the data request message is generated and transmitted to the smart power distribution system 200. When the data write message is transmitted from the smart power distribution system 200, the power distribution processing processor 121 stores data in the power distribution processing memory 122 in accordance with the IEC 61850 data model format.

In addition, the power distribution processing processor 121 reads data to be delivered to the AMI system 300 from the power distribution processing memory 122 and transfers the data to the shared memory unit 130 to store the data. The power distribution processing processor 121 sets a flag indicating that there is an interrupt signal or data so that the AMI system 300 receives the corresponding data. When the power distribution processing processor 121 confirms that a flag indicating that there is an interrupt signal or data is set from the AMI system 300, the power distribution processing processor 121 reads data from the shared memory unit 130 and stores the data in the power distribution processing memory 122.
