| Popis: | In order to effectively analyze the torsional vibration characteristics of turbo-generators, this paper designs and implements a torsional vibration monitoring systen via virtual instrumentation technology. The system hardware adopts PXI system. The system software is developed by LabVIEW language. The monitoring system records speed signals from the turbo-generators and extracts directly the total torsional vibration from the speed signals utilizing zero-phase digital filter. It seperates torsional vibration modes from the total torsional vibration and analyzes the corresponding characteristics of each mode. Field tests were conducted in a real power system to verify the performance of the monitoring systemThe results show that the torsional vibration measurement system detects the torsional vibration of turbo-generators accurately and the system fulfills the practical application demands. |
