철도변전설비 표준 통신프로토콜 IEC61850 연계용 Gateway개발

AC protection relay with an electric railway system is the equipment by different domestic and international product specifications There are many difficulties in communication between the higher-level low-level system settings. This using the device-to-device operation and maintenance standard data for substation communication protocol IEC61850 system established as an international standard model to increase the efficiency of in order to compensate provides the same modeled between each device interoperability between devices according to the IEC61850 standard, and it shall be guaranteed. In addition, some of the system configuration described, even if the rapid development should be provided to improve the maintenance functions that can accommodate the advanced features. To study this, the development of Gateway for connection to perform the current functions of the IEC61850 protocol conversion between DNP3.0 based SCADA-based substation and what is the purpose of the protocol conversion and intermediary role between protective relays.
