摘要：In this paper, the test data and storage management, data analysis and other aspects of the signal presented the turbine tube vibration system design ideas and methods. Describes a vibration analysis of tube effective method: Based on HHT spectrum of EMD turbine to extract the dynamic characteristics of information and software to be achieved. The results show that the method of high accuracy, and has a good feature vector extraction turbine capacity, suitable for analyzing complex and dynamic characteristics of turbine specific information; and the system has strong versatility and scalability, and achieve a good real-time performance. No. 1 in a hydropower station on the real machine test, experimental results show that the system can effectively monitor the vibration of the draft tube.
