摘要
设计一种风力发电机振动保护仪。它是集振动和转速保护于一体的模块,采用加速度传感器、转速传感器等硬件,提取有用频段内的信号,通过程序判断,当信号值大于设定的正常值时,发出一个开关量信号执行停机操作,完成对风力发电机的振动保护。当叶轮转速过高时,通过转速传感器采集的信号进行过速保护。
Designed one kind of vibration guard module of wind turbine. It is a combined vibration and RMP guard module. It measures vibration by analyzing the signal from an aceelerometer and RMP by measuring pulse time from a taeho. Withdraws the signal of the useful frequency band and through procedure judgement, when the signal value is bigger than the normal value, sends out one switch signal to stop. When the rotational speed is excessively high, through the signal of tacho carries on the rotational speed protection.
