基于提升格式小波变换风电振动监测系统研究

摘要

Wind turbine vibration monitoring and fault diagnosis system for normal operation is one of the most safe and reliable method to ensure the stability and wind field operation cost down.This paper respectively from three aspects,such as ascending format the basic principle of wavelet transform,the introduction of vibration monitoring system and data acquisitionmethod,wavelet transform and improve format used in the monitoring system and so on.Verified by the experimental data to prove the superiority of wavelet transform monitoring system which use the ascension format.%风电机组振动监测及故障诊断系统的正常运行是保证风场运行稳定和降低成本的最安全可靠的手段之一.该文分别是从提升格式小波变换的基本原理、振动监测系统的介绍和数据采集方式、以及提升格式小波变换在监测系统中运用3个方面进行阐述.通过试验数据验证了运用提升格式小波变换的监测系统的优越性.
