TORSIONAL VIBRATION ANALYSIS FOR WATER AND STEAM TURBINES

To prevent damage, there is the possibility of monitoring mechanical systems during operation. If 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 apply a highly dynamic monitoring system to the systems. A monitorable parameter here is the vibration angle of the turbine rotor. 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 powerful measurement technology for a fast shutdown, which enables data evaluation and data transfer. A too late shutdown can result in lasting damage to the turbines. An example of this is the operation of the rotor in the range of the natural frequency, which is not permitted for a certain time.
