Abstract: . . .  As part of a plant refurbishment and upgrade project, a new Generator Control System is to be installed. Once this is in place, suitable SCADA data will be available to HydroX and thus the data acquisition subsystem software will be installed and debugged at the site. The final phase of the project then involves extending the tested data acquisition components by adding the Expert System and Expert System GUI programs. The system is expected to be operational on unit 26 at the St Lawrence plant during 2003. Page 9 Conclusions Advances in technology have resulted in an increase in the number and complexity of hydraulic generator monitoring systems. Unfortunately, advances in system integration have not kept pace, resulting in “islands of technology” and a proliferation of complex systems to be dealt with by operators and maintainers alike. The HydroX project will be the first fielded system to provide a vendor independent architecture to “glue” diverse hydrogenerator monitoring systems together (SCADA, PDA, Airgap, Vibration). The result of this work will be a completely integrated and vendor non-specific architecture for sensor data collection and trending displays, coupled to a real time diagnostic expert system for hydraulic turbine/generator condition monitoring. In the future, the HydroX could be further extended to couple to a plant-wide monitoring and diagnostic system. References 1. A. Roehl and B.
