摘要
本文介绍共用直流母线多电动机变频调速系统在涤纶短纤维生产线上的应用,其突出优点是可以自适应调整不同牵伸比条件下被拖电动机的制动力矩,确保牵伸比控制精度;制动能量可回馈电网,起到节能作用。
The article describes common DC bus multi-motor VVVF system in terylene short fibre product line application. The prominent feature is that it＇ can auto-adaptive adjustment braking torque of motor in different tension scale, insure the control precise, braking power can feedback the power network, play an important role in energy-saving.
