On-line Monitoring, Diagnostics & Predictive Maintenance
Within our comprehensive portfolio of Siemens products and services for generators, digital services are an essential and future-orientated area for us as well as for our customers. We offer customized solutions for reliable on-line monitoring, predictive maintenance and digital data analysis for generators and high-voltage equipment. The modular products and services of our predictive maintenance or on-line monitoring systems allow flexible configurations to provide tailored solutions.
GenAdvisor™ Monitoring and Diagnosis System
The modular GenAdvisor™ platform provides various systems for monitoring Siemens generators as well as generators from other manufacturers. Each system can be used individually or in combination with a central server and other monitoring systems.
With GenAdvisor, Siemens provides you with customized solutions for reliable in-service monitoring of generators and high-voltage equipment. Advance recommendations based on generator condition can enable scheduled outages to be optimized and shortened, as necessary repairs and spare parts ordering can be planned in advance.
Fiber Optic End Winding Vibration Monitoring
The high electromagnetic flux and currents created inside a generator can lead to end-turn basket vibration on some units. Generator stator end winding vibrations can loosen the winding, weaken insulation and ultimately crack conductors.
Siemens pioneered Fiber Optic Vibration Monitor (FOVM) technology to directly measure end winding vibration in the early 1980s, and now offers the Fiber Optic Vibration Monitor Model 4, the latest and most advanced monitor of its kind.
Digital Torsion Monitoring
Excited by power system transients, load unbalances and disturbances, turbine-generators can be susceptible to torsional vibrations occurring at or near rotor torsional natural frequencies. When torsional vibrations are excessive, the resulting cumulative fatigue damage can reduce life in components such as shafts, rotors and blades. If high levels of torsional vibrations continue without corrective action, severe component breakdowns can occur, causing equipment damage and forced outages.
Siemens offers an advanced monitor – the Siemens Digital Torsion Monitor (DTM). It can be applied to all OEM turbine-generator configurations. The monitor features engineering analysis capabilities and customized settings for monitoring the level of torsional vibrations.
