摘　　要：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 digitizing revamping of 7-stand finishing main drives in 1 700 mm hot strip mill of WuhanIron and Steel Co is accomplished by means of system integration with Logidyn-D2 of AEG CEGELEC. Several key problems for 12-phase rectifier of large DC drive are solved, such as the oscillation problem in the power supply system. After revamping, the specifications of finishing main drives are improved remarkably.Through long time operation, it has been proved that the system reliability is very high.
