Traditional electric power regulator, which is based on thynstor ann takes mtemgent algltal controt circuit as its core, is used in the metallurgical, chemical areas as power control device for electric heating equipment, it is facing such serious problems as low power factors, poor communication functions, low control accuracy and large working harmonic wave. We design a new kind of digital intelligent electric power control device, which implements the electric network power control and intellectualization by using computer control, microelectronics,and power electronics methods. This design implements centralized control and management of multiple adjustments by using 485 serial port communication and power output uniform distribution algorithm technologies, it also perfects the over-load and load short circuit protection function by using digital control to improve the reliability and stability of equipments, and to meet the requirements of cluster control under mass production environment. It is characterized with easy-setting of ccontrol parameters and process parameters, high control accuracy, high power utilization, super overload and short circuit protection capability, security and stability. The experiment data indicate that the work has met the accuracy requirements of the original design, and greatly improved the efficiency in the use of power.
