µ-Sen uses Condition Monitoring Systems for early fault detection for the main components (main-bearing, gearbox, generator) of wind turbine drive-trains
The CM-Systems "Ω-Guard®"and "VIBGUARD®" have been installed in more than 700 wind turbines since 2001 (40 different types of wind turbine from 11 manufacturers). The wind turbines being monitored have power outputs ranging from 250 kW to 5MW.
The CM-System "VIBGUARD®" was introduced to the market place as a standard solution for onshore wind turbine systems at the end of 2006. The CM system has been optimised in co-operation with "Prüftechnik Condition Monitoring GmbH" and is certified by ATZ (Allianz Zentrum für Technik GmbH) as well as Germanischer Lloyd WindEnergie GmbH.
The initial evaluations of the measured values, their storage as well as the data transfer, is carried out automatically by the CM System. The configuration of the diagnostic system is implemented through the web front-end "WebLog" either on site or at a remote monitoring position. The WebLog also serves as a communications interface for the diagnostic system and enables easy access to the condition information from any geographical location. The user is alerted of possible problems via a status window as well as via e-mail or SMS. A simultaneous trend analysis of the individual machine components and equipment is made available using the integrated database.
The basic concept used by µ-Sen for the low frequency diagnostics of the drive-train of a wind turbine system consists of acceleration sensors and mechanical vibration sensors as well as rotational sensors. The modular design ensures that additional sensors can be used to complement or extend the monitoring system or monitor other physical measurable characteristics such as vibration frequency, vibration amplitude, particle count, power output, wind speed, temperature and pressure. Furthermore, the monitoring of the operation and condition of the rotor blades can be integrated.
