Bay integrated power system control and diagnostics
The paper presents new concepts for control and diagnostic systems for high voltage switchgear (123-kV and above). Air insulated and gas insulated (SF6) switchgear is considered. The new aspect is the integration of monitoring and diagnostic concepts in digital control and protection systems. Communication concepts for sensors and actuators with digital process busses at bay level are discussed. The paper covers integration concepts for circuit breaker monitoring (AIS, GIS) and for GIS the integration of on-line partial discharge measurement, on-line arc detection and on-line monitoring of the gas conditions. Finally, the advantages, disadvantages and the applicability of integrated diagnostic and control concepts are discussed by means of technical and commercial aspects.
