The thesis designs a frequency-power automatical control unit based on PLC, enabling generators to run reliably even if in the event of heavyload fluctuating.
本文设计了一种基于PLC控制的自动调频调载装置，可使发电机组在大负荷波动的情况下也能可靠地运行；

It is featured by its precise output control. Therefore, it could be applied to where the working conditions of heavyload, micro and precise movement are required.
该驱动装置能够实现精密输出控制，可以用于需要大负载、微量精密位移的应用场合。
