Abstract

The hydropower generating units vibration parameter is an important indicator to monitor its roll-stabilization. To measure the low-frequency vibration of the large and middle scale of hydropower generating units, according to frequency characteristic compensation principle of the vibration sensor, a low-frequency compensating circuit was designed to extend the frequency characteristic to the low frequency region. The mathematical model of the magnetoelectric dromometer vibration sensor and the design of the compensation circuit were detailed. The amplitude-frequency characteristics of the sensor and its mathematical model were comparatively analyzed before and after compensation respectively. The experimental result shows that the design could extend the amplitude-frequency characteristics to the low frequency region ,and have good sensitivity and linearity.
