Uses of the Intelligent Dynamic Power Factor Compensation Device in the Cold Mill

The intelligent dynamic power factor compensation device,which may realize the automatic tracking and fast compensation of the power factor using the single chip microcomputer,will decrease the cur- rent through the electric machine stator and the temperature rise of the electric machine.The device has many good characteristics,such as high response speed,great reliability,compactness,the lower harmonic,the bet- ter adaptive capacity to environment,expedient installation and debugging.In the power supply system of cold mill,the intelligent dynamic power factor compensation device may increase power factor,suppress harmonic and voltage flickering,improve the voltage stabilization level and transmitting capacity of power system.
