摘要
根据小波包的重构和分解对发电机组进行振动信号分析,并提取了发电机组某个频率段的特征振动信号,对这频率段的振动波形进行分析与研究,找出引起该故障的主要原因,验证该方法的有效性和可行性,为技术人员提供参考和借鉴。
According to reconstruction of wavelet packet and decomposition of generator vibration signal analysis. Extracting generator shows a vibration signal characteristics. The vibration waveform shows a research and analysis, find out main reason that causes this fault, verify feasibility and effectiveness of method for technical staff, and offer reference to reference.
