传统的电力调整器作为冶金、化工等领域电加热设备专用的以晶闸管为基础、智能数字控制电路为核心的电源功率控制设备,面临着功率因数低、通讯功能差、控制精度低以及工作谐波大等严重问题。因此设计了一种全数字化的智能电功率控制装置,利用计算机控制、微电子技术、电力电子技术等方法,实现了电力功率控制的网络化和智能化;采用485串口通讯、功率输出均匀分配算法等技术实现了多台调整器的集中控制与管理。并且以数字化控制方式完善了过载和负载短路保护功能,提高了设备的可靠性和工作稳定性,满足了大规模生产环境下集群控制的要求。具有控制参数设置和工艺参数设置方便、控制精度高、电能利用率高、过载和短路保护能力强、安全稳定等特点。通过试验分析,得到的数据结果表明其工作满足了当初设计的精度要求,极大程度的提高了电源功率的使用效率。

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.
