Intelligent substation automation-monitoring and diagnostics in HV switchgear installations

摘要

Expanding on modern substation automation, in which all the bay-oriented functions are integrated in the bay cubicle, efforts are now being focused on moving the 'intelligence' even closer to the primary process. A precondition for this are new,'smart' sensors and actuators for all the main measurements and setpoints, linked to each other and to the bay control level by a field bus. Such a concept allows cost-optimized, fully redundant acquisition and processing of all the operating variables,plus a diagnostics and monitoring system that covers the entire substation.
