| 摘 要： | 水电机组振动是表征水电机组运行稳定性的主要指标之一。然而，水电机组转频太低，适合于使用测量低频振动信号的惯性式低频振动传感器。由于传感器本身频率特性，造成其输出波形的低频段必然产生较大的畸变。为了获得实测低频振动信号的真实波形，对振动传感器输出的畸变波形恢复问题进行了初步探讨。

| Abstract: | The vibration of hydrogenerator unit is the main parameter to represent whether the hydrogenerator unit runs steadily,but it's rotating frequency is so low that when measuring the vibration with the inertial low frequency vibration transducer,the output signal,especially the low frequency component is distorted seriously because of the transducer's frequency characteristic.This paper preliminarily discusses how to restore the distorted signal. |
