摘要
介绍了采用罗氏线圈测量二次电流替代传统的铁芯式互感器检测是重要的创新,并以此设计恒阻抗PID调节器,改造了多个钢厂的电弧炉和精炼炉控制系统,取得了良好的效果。
It introduces an important innovation to use Rogowski coil to measure secondary current instead of traditional iron-core mutual inductor detection.Based on it,constant impedance PID regulator is designed and the control systems of EAF and refining furnace in several steel plants are reformed,and good results are achieved.
