Research and Development of Acoustic Emission Signal Monitoring System for Hydraulic Turbine Cavitation

Abstract:

The existance of cavitation threatens hydraulic turbines’ safe and economical operation. Traditional caviation monitoring methods are inclined to be contaminated by low-frequency environmental disturbances and strong background noises. An acoustic emission signal monitoring system for hydraulic turbine cavitation is proposed. Its hardware and software configurations are described in details, as well as the main functional modules. The test results on an 8000 kW Francis turbine with cavitations in the draft tube have shown the merits of this proposed system.
