Preventing the development of emergency modes of interlocked electric drives of a rolling mill under the impact loads
Diagnostyka(2022)
摘要
In recent years, due to the tightening of competition in the global market of steel producers, the requirements for the quality of hot-rolled steel have increased.The finishing group of the rolling mill is characterized by a complex structure of mechanical and electrical parts.The operation of electric drive systems of such units is characterized by the interrelation of electromagnetic processes, mechanical phenomena and technological factors.As experimental studies have shown, the quality of the supply voltage is inextricably linked with the impact nature of the loads in the rolling stands of the roughing and finishing groups of the hot rolling mill.A decrease in the supply voltage may be accompanied by the development of emergency modes of synchronous electric drives, leading to a decrease in the quality of the finished product.The paper developed a mathematical model of the power supply system of the rolling mill JSC "ArcelorMittal Temirtau".It is shown that this can lead to loss of synchronism of the synchronous motor.Such a voltage drop has a significant impact on the operation of DC electric drives of the finishing group.Various strategies are proposed to counter the development of emergency situations.
