Small Hydro Condition Monitoring - Solution Presentation Brochure

SMALL HYDRO CONDITION MONITORING (SHCM) Monitoring of Hydro Turbines ? Hydro turbines are especially vulnerable to number of parameters that constantly reduce their life time. ? Various types of damages develop as a result of mechanical forces, material destruction, mechanical contusions, large differences in temperature, cavitation, corrosion, chemical forces, etc. ? Continuous measurement and tracking of harmful parameters can help in setting alarms that prevent malfunction development. System Overview of SHCM Operator panel - HMI Ethernet Web HMI Remote user Processing/protection unit SHCM Front End Relative displacements Accelerations, vibration speeds Analog/digital signals Rotating speed SHCM Monitoring Cabinet - Processing unit with DB & web server - Signal conditioning units - Power supplies - Communication – media converter - Digital relays – alarms SHCM Function Monitored values: • Radial relative bearing displacement – Smax • Radial & axial absolute bearing vibrations – RMS • Axial shaft displacement – DC • Speed profile – RPM Processed values: • Online view • Alarms • Trends/RT Trends • Spectrum/RT Spectrum • Orbit/RT Orbit Diagram User Interface – Web Application Integration of Several Hydro Plants The Benefits of Integration • Unique approach for all equipment • Supported preventive maintenance • Extended life cycle of equipment • Support in decision-making related to the maintenance or replacement • Consolidation of data acquired through monitoring and diagnostic tests • Reducing the cost of unplanned downtime • The participation of users in the creation of a unique system according to their requirements (custom designed solution) Applicable to Large Hydro Plants as well HPP Pamilo, Finland 1 x 34 MVA Example of application of the upgraded system version
