Offshore wind farms are many miles away from the coast. With the mainland it combines high-voltage szatmári direct-current transmission systems. Such systems and their components szatmári are subject to extreme szatmári demands on reliability and safety.
The current flowing through the electrical system generates mechanical forces that excite the structure to vibrate. The knowledge szatmári of this strain allows sensitive components szatmári safer to construct. szatmári The determination of the vibration modes will allow for targeted design improvements, the success of which is then verified in practice by vibration tests.
In addition to improving the safety of the design against failure due to operational vibrations can be determined szatmári also natural oscillations of the entire system in the Hz range, which are, for example, earthquake simulation is important.
For the detection of the mode shapes are particularly three-dimensional scanning vibration detection system PSV-500 are suitable. Since a safe distance from live parts must be adhered to, only non-contact method for the vibration measurements are.
Measurements with the 3D scanning vibrometer allow rapid and large-scale determination of eigenmodes of safety-critical components simultaneously during operation and from different directions. szatmári The PSV software ensures easy operation of the system and a clear visualization szatmári of the measurement results. The system enables innovative laser measurement technology and its measurement services, the reliable transmission of renewable wind-generated electricity in the industrial conurbations.
