Vibration Test and Analysis of Ocean Booster Stations
摘要
Abstract
The voltage generated by the offshore wind farms needs to be transported to inland after boosting by ocean booster stations. Vibration detection and analysis are the important means for the daily safety maintenance of the ocean booster stations. In Jiangsu province, an ocean booster station of the offshore wind farm had a strong sense of vibration. In order to test the structural health and the actual vibration situation of the booster station, a vibration detection system was set up. The data of horizontal and vertical vibration accelerations and vibration velocities of the first and fourth floors of the booster station was measured. Then, the time history diagram and the self-power spectrum of the data were analyzed. It was found that the vibration intensity of the booster station increases with the rise of the floor, the vibration of the mechanical and electrical equipment has a great influence on the local vibration of the booster station and sometime the influence can be very serious. The first order natural frequency of vibration is low, and the vibration energy of the structure is mainly concentrated at this frequency. The main vibration frequencies of the first floor and the fourth floor have slight deviations in all directions, but the deviations are all less than 1 % . The results of test and analysis show that the influence of the mechanical and electrical equipment on the local vibration of the booster station is obvious and there may exists loose structural connection in the booster station. This study may provide some reference for the rapid fault diagnosis of the ocean booster stations.关键词
