Objectives: The energy consumption increased day by day. To reduce the peak power demand, there are many studies of Distributed Energy Resource like emergency generator and renewable energy. Methods/Statistical Analysis: In Korea, emergency generator capacity is 21GW. If some of emergency generators utilize, it efficiently reduces peak demand. However, the emergency generator is spread all over the country, it need to monitoring and integrating technology by remote site. Findings: IEC 61850 is standard of integrating automation substation and IEC 61850-7-420 describes LNs of Distributed Energy Resources. So, we check up the selection and installation regulation of emergency generator by KOSHA CODE and sort the check list like temperature, pressure in system. So, we installed the various sensors (oil temperature, coolant temperature, oil pressure, fuel level). The sensor value output is 4 to 20mA analog data. The controller coverts analog to digital data with Modbus protocol and IEC 61850 gateway creates IED mapping Modbus to IEC 61850. The data transfer VPN with TCP/IP protocol and it can monitor the remote site. Improvements/Applications: The proposed system can supply smart service to users with IoT technology and they can predict generator fault and reduce the accident. Furthermore, this system can adapt other Distributed Energy Resources.
