摘要
变频传动装置属于调速驱动系统的一种,主要应用于工业现场、试验室的交流电机控制中,通过改变交流电动机的输入电压的频率和大小,来实现电动机转速精准控制。西门子SM150中压变频器用于要求严格的驱动,可以满足高动态、低频操作以及四象限操作的要求,那么变频器调速方法对于应用效果至关重要。本文根据日常运行经验,总结了SM150变频器的调速原理及参数调节方法。
Variable frequency drives(VFDs)belong to a type of speed control drive system,primarily used in AC motor control in industrial sites and laboratories.By altering the frequency and magnitude of the input voltage to the AC motor,precise control of the motor's rotational speed is achieved.The Siemens SM150 medium-voltage VFD is suitable for demanding drives,meeting requirements for high dynamics,low-frequency operation,and four-quadrant operation.As such,the speed control method of the VFD is crucial for its application effect.Based on daily operational experience,this article summarizes the speed control principles and parameter adjustment methods of the SM150 VFD.
