随着交流变频控制技术的不断发展,交流传动系统得到广泛应用。交流变频调速是强、弱电混合,机电一体的综合技术,既要处理巨大电能的转换,又要处理信息的收集变换和传输。因此它的共性技术必定是分为功率和控制两大部分。前者要解决与高压大电流有关的技术问题和新型电力电子器件的应用技术问题,后者要解决硬、软件开发问题。各种高性能变频控制都是国内外研究的热点。首钢京唐氧枪控制系统采用690V AFE变频器控制,完成氧枪重载启停、能量转换、智能调速等,具有启动力矩大、响应速度快、在运行过程中速度均匀可调,并可实现快速加减速的优势。
With the continuous development of AC frequency conversion control technology, AC drive system has been widely used. AC variable frequency speed control is strong, weak hybrid, mechanical and electrical integration of technology, it is necessary to deal with the conversion of huge power, but also deal with the collection and conversion of information and transmission. Therefore, its common technology must be divided into two major parts of power and control. The former to solve the technical problems related to high-voltage high-current and the application of new power electronic devices technology, which should solve the hard and software development issues. A variety of high-performance frequency control are the hot spots at home and abroad. Shougang Jingtang lance control system with 690V AFE inverter control, complete oxygen launcher heavy load start and stop, energy conversion, intelligent speed control, with a large starting torque, fast response, the speed of operation is uniform and adjustable, and can be Advantages of rapid acceleration and deceleration.
