炼钢厂多电机传动同步控制策略

Multi-motor Drive Synchronous Control Strategy in Steelmaking Plant

多电机传动调速系统在炼钢厂得到广泛应用,多电机传动调速设备的同步控制策略对炼钢系统的高效稳定运行起着决定性作用。研究多个近年实施的炼钢工程项目,总结炼钢厂使用的多电机传动同步控制策略主要有:并行控制方式、非耦合控制方式、耦合控制方式和PLC实现速度控制器方式。基于使用的设备类型和工艺要求不同,炼钢厂多电机传动同步控制又有四种不同的硬件实施方案。

Multi-motor drive speed regulation system has been widely used in steelmaking.The synchronous control strategy of multi-motor drive speed regulation equipment plays a decisive role in the efficient and stable operation of the steel-making system.A number of steel-making projects implemented in recent years are studied,and the synchronous control strategies of multi-motor drive used in steelmaking are summarized as follows:parallel control mode,decoupled control mode,coupled control mode and PLC speed controller mode.Based on the different equipment types and process requirements,there are four different hardware implementation schemes for the synchronous control of multi-motor drive in steel mills.
