Experience with an on-line Hydro Generator Expert System Monitoring system
Current technological advances in condition monitoring are employing an increasing number of complex sensors and advanced monitors to diagnose the operating status and condition of hydro generators and turbines. Advanced systems routinely employed may include bearing vibration, air gap, shaft voltage, and current monitoring, partial discharge, and flux monitoring. Proper interpretation of this often complex information can lower operating and maintenance expenses, in addition to reducing unscheduled outages and catastrophic failures. However, the volume of available data from these monitors, and the extensive interpretation necessary to evaluate the complex waveforms and spectrums can overwhelm plant personnel and resources. Sophisticated software and algorithms are often necessary to correlate and interpret this data to establish the overall generator and drive train condition. HydroX™ (for Hydro Expert) is a commercial knowledge-based expert system program for on-line monitoring of hydro-generators. Working with the New York Power Authority, the system was developed over five years by Iris Power and GE -Bently Nevada. After a further two years of prototype evaluation at NYPA’s St. Lawrence Power Project on two 60MVA generators, the validated system is now commercially available and will be described.

Iris Power
Blake Lloyd, PEng. Fellow IEEE, Director – Product Development, Iris Power.
Mr. Lloyd is an Electrical Engineer with extensive experience in instrumentation and product development. In past lives, he worked in software development and then in the Electrical Research Department at Ontario Hydro, where he was responsible for conducting research into advanced measurement, testing, and diagnostic monitoring techniques for rotating machines and insulation systems. Since co-founding Iris Power in 1990, Mr. Lloyd has been one of the principle architects of Iris’s line of diagnostic instrumentation and analysis software for rotating machine condition assessment. Products include on-line partial discharge monitoring, air gap flux monitoring, current signature analysis, end-winding vibration, shaft voltage and current monitoring, as well as several off-line test instruments. Mr. Lloyd has two US patents, and has published 20 refereed papers in IEEE and CIGRE, as well as over 40 conference papers. He has been a Member of IEEE since 1985.
