摘要
介绍了一种解决轧制系统负荷不平衡的控制方法。针对莱钢1 500mm宽带粗轧主机上下辊电机电流差值大现象,利用SIMADYN D全数字32位机矢量控制交交变频控制调速系统,在STRUC G程序中建立负荷平衡控制模型,实现了负荷平衡控制功能。使系统运行稳定可靠,控制精度高,速度响应快,能更好地满足生产工艺的要求。
A method to solve load imbalance in roll system was described.Aiming at the big difference motor current in the 1 500 mm Laigang broadband for roughing up and down roller host,the SIMADYN D all digital 32 bit machine vector control speed cycloconverter control system was used to set up STRUC G load balancing process control model,develop and improve the load balancing control functions to solve the load imbalance.The system is stable and reliable,has high control precision and fast response speed,can meet the process requirements better.
