A coordinated design framework for power system automation

This paper presents a coordinated design of power automation platform for integrating the various power automation sub-systems. It closely follows the IEC standards (IEC61970, IEC61968, IEC61850) and meets the high demands on operation performance, reliability, expandability, openness and security of modern power system control and management. The design introduces two new concepts: operation oriented architecture (OOA) and multiple redundancy, or 1xM redundancy. It also includes a high speed open database connection to various RDBMS databases and an open interface layer to different computer operating systems. Other advanced features are also provided in the new design, including the distributed real time database, the data subscribing mechanism, GUI-based data model editing tools and the full version management mechanisms.
