TORSIONAL VIBRATION ANALYSIS FOR WATER AND STEAM TURBINES

For damage prevention, there is the possibility to monitor mechanical systems during operation. In this case, when a critical level is exceeded, measures are taken to prevent damage to a power generation plant. In order to take these measures, it is important to install a highly dynamic monitoring system on the equipment. One parameter that can be monitored is the vibration angle of the rotor of a turbine. The simple embedding of the measurement technology in existing control and regulation devices is a decisive factor here. The highly dynamic effects of the rotor shaft, require for a fast shutdown a powerful measurement technology, which allows not only the evaluation of data but also a transfer of the data. Too late a shutdown can result in lasting damage to the turbines. An example of this is the unacceptable operation of the rotor in the range of the natural frequency.
