Research on Online Standby Running of Power Automation System Based on CORBA

Performing the CORBA-based CIS (Component Interface Specification) services of IEC61970 is an important part in integrations of power automation system applications. Because of high requirement of the reliability and continuity in power automation system, implementing online standby running modules by CORBA-based software is becoming an indispensable function. This paper studies how to manage online standby running for the CORBA-based services on the basis of online standby management of SoftBus developed by iESLab. In this paper, two practicable ways to realize online standby running based on CORBA are presented and the difference between them is discussed in detail.
