摘要
随着整流装置功率加大,它所产生的谐波、无功功率等对电网的干扰也随之加大,为减轻干扰,可采用多重化整流电路。针对无缝钢管厂阿塞尔轧机系统,结合主从控制思想及工业网络的应用,提出了大功率直流传动系统12脉动控制方式,介绍了该系统中主要电气元件选型及技术参数计算的方法。实践证明,此方法结构清晰,波形良好,输入电流谐波大幅减少,一定程度上提高了功率因数,系统稳定可靠,能满足较高的工艺要求,值得在大功率直流控制系统中广泛应用。
As the power raising of rectifier,the disturb of harmonics and inactivity to electric network becomes severe.To reduce the disturb,we can use the multiplex rectifier.The 12 pulse control method of superpower DC drive system was put forward,which depends on ASSEL mill of seamless steel pipe,master slave idea and network construction.It introduced the election and calculation of electric element.Approving by experience,this method is obvious in fabric,wave is fair,the disturb of harmonics is reduced to electric network and the power factor is raised.The system is stabilize and credibility.It can meet stringent specification technology,the system should be spread to superpower DC drive system.
