Abstract :
The standard way to deploy substation network information system is based on IEC61850 ´Communication Networks and Systems in Substations´, which is confined to individual substation domain. In order to develop cross-substation applications without affecting the lower level operation mode, the information class model defined in IEC61850 needs to be expanded. Another dilemma is that the object oriented data model defined in IEC61850 cannot be simply mapped into relational database model. In this paper, a LDAP (lightweight directory access protocol) based middle layer is proposed to resolve these two problems. Through the invoking of LDAP layer, the storage and access of self-descriptive structural information model are realized, and the name space of basic information model is expended. The approach supports a seamless integration of substation information models. Based on this layered architecture, cross-substation applications and global visualization can be deployed.
