Research on unified information model for big data analysis of power grid equipment monitoring

With the integration of power grid developing further, some demand such as power grid analyses decisions centrally has become more and more urgent. At present, the information resources for the use of Power grid equipment monitoring analysis is becoming abundant, but these information, which exists in every professional system independently, is lack of connection and meets the demand of big data analysis on power equipment monitoring hardly. In this paper, a unified information model, modeled by IEC61970 common information model and IEC61850 hierarchical model, is proposed for the analysis of big data monitoring in power grid equipment, which can establish the first and second Equipment Association within the scope of the grid equipment monitoring data, as well as realize centralized access to all measurement information in the method of extending measurement model. This is significant to promote the process of deepening application of power grid equipment monitoring.
