采用Logidyn－D2控制器进行系统集成，完成了武钢1700mm热轧机精轧7机架主传动电机的数字化改造，解决了大型直流传动12相整流环节中的几个关键问题，如原系统在大负荷时的电网电气振荡问题等。整机改造完成后，性能指标大幅度提高。经长时间运行证明，系统具有很强的可靠性。
The Logidyn-D2 controller was used for system integration and the digital transformation of the main drive motor of 7-stands of 1700mm hot rolling mill of WISCO was completed. Several key problems in 12-phase rectifier of large DC drive were solved. For example, Load electrical grid oscillation problems. After the transformation of the complete machine, the performance index has been greatly improved. After a long run proved that the system has a strong reliability.
