The present invention relates to a power equipment condition monitoring and diagnosis (CMD) data converting method for a smart grid, which can provide compatibility between data structures when a data node and a sensor node installed for CMD have different data structures. A CMD data converting method according to a preferred embodiment of the present invention comprises the steps of: receiving, by a data node, a conversion reference information ID and data conversion reference information identified by the conversion reference information ID from a sensor node; registering, by the data node, the data conversion reference information having the conversion reference information ID matched thereto on the data node; receiving, by the data node, monitoring data, a sensor node attribute information ID, and a data conversion reference information ID from the sensor node; acquiring, by the data node, a data class-data attribute by preparing PD-LD-LN information using the sensor node attribute information ID and converting the monitoring data using data conversion reference information identified by the data conversion reference information ID; and transmitting, by the data node, data having an IEC 61850 data structure having a PD-LD-LN-data class-data attribute layer architecture to a monitor node. |
