变频控制在PF链上的研究应用

Research and Application of Variable Frequency Controlling Technique in the PF Chain

对PF链的传动控制系统进行了变频控制改造,即保持原工频供电系统不变,新增一套变频电源供电系统,采用PLC-变频器的控制方式,控制变频器的启动、运行、升速、停止。利用变频器极方便的调速性能,实现了PF链的变频提速,满足了现场快节奏生产运行的要求,极大地提高了设备运行效率,从而提高了产量,使效益最大化。这种方法可以在相关领域得到广泛推广应用。

The variable frequency controlling reconstruction to drive system of PF chain was carried out,namely maintained the original constant-frequency power supply system,added a variable frequency power supply system and controlled the starting,running,accelerating and stopping of frequency converter by adopting PLC-transducer controlling mode.Utilizing the optimum accelerating performance of frequency converter,achieves the variable frequency and acceleration of PF chain,meets the demand of the field fast rhythm production running,and greatly enhances the efficiency of the equipment,thereby increases the yield and maximizes the efficiency.This method can be widely applied in related fields.
