CORBA-based substation automation systems
Proceedings of the 2001 IEEE International Conference on Control Applications (CCA'01) (Cat. No.01CH37204), 2002Describes the implementation of the emerging IEC-61850 standard for automation systems using a CORBA middleware as communication mechanism. This standard specifies communication mechanisms for automation systems in electric substations. CORBA-based implementations of control systems open new perspectives for advanced control, because they ease the ...

Feeder Automation within the Scope of Substation Automation
2006 IEEE PES Power Systems Conference and Exposition, 2006This paper presents the commonly used approaches to feeder automation (FA) and introduces a practical approach to implementing feeder automation that is virtually a simple extension of the substation automation by covering the feeders. FA is usually implemented either based on a centralized approach or a distributed approach.
