基于SL150的热连轧传动系统的控制与应用

Control and Application of Hot Continuous Rolling Drive System Based on SL150

SINAMICS SL150是西门子公司新型全数字矢量交交变频控制系统,用于替换上一代产品SIMADYN D系统。在SL150系统中,针对冶金轧制有一些特殊的应用,包括负荷平衡、负荷观测、陷波滤波器等,其中负荷平衡保证了上下辊输出转矩的平均分配,采用负荷观测器的控制系统具有较强的抗负荷扰动性,明显减少轧机动态速降和恢复时间,陷波滤波器的运用消除了机电共振现象,这些应用对生产线的正常快速生产、保证产品质量发挥着重要作用。

SINAMICS SL150 is the new digital vector AC-AC frequency conversion control system of Siemens company, used to replace the SIMADYN D system. In the metallurgical rolling, there are some special applications, including load balance, load observer, notch filter, load balance guarantees the average distribution of output torque of roll, the control system of the load observer had a strong anti load disturbance, obviously reduced the mill dynamic speed drop and recovery time, The usage of notch filter eliminates the electromechanical resonance phenomenon. The application ensures the normal rapid production and plays an important role in the quality of the products.
