摘要

With the gradual popularization of DAS (Distribution Automation System), the amount of automated switches continues increasing as well as the amount of analog and digital values, the traditional relational-based real-time database is relatively difficult for distributed acquisition and processing of switch data. This paper presents a scheme of object-oriented real-time database compatible with IEC61970-CIM standard. Basic models of distribution network and their relations are described; tables are deployed according to equipments individually. Primary object relations are realized including association, composition and inheritance. Message mechanism is implemented by classes encapsulating SCADA functions. The conversion and automatic generation of distribution object models are analyzed; the procedure of database loading is described. Some performances including quick retrieval, parallel and distributed processing are analyzed based on practical engineering applications.
