随着电力电子技术以及自动化控制技术的发展,使得交流变频调速系统,软启动调速系统在工业电机拖动领域得到广泛应用,另外,由于PLC功能强大,容易使用,高可靠性,常常被用来作为现场数据的采集和设备的控制,本文简要分析了PLC、变频器、软启动系统的技术特点,及在煤矿领域上的典型应用,对PLC、变频器控制系统、软启动控制系统进行了探讨。
With the development of power electronic technology and automation control technology, AC variable frequency speed control system and soft start speed control system are widely used in the field of industrial motor drive. In addition, because PLC is powerful, easy to use and highly reliable, it is often used Used as the field data collection and equipment control, this paper briefly analyzes the PLC, the frequency changer, the soft start system technical characteristic, and in the coal mine domain typical application, to PLC, the frequency changer control system, the soft start control system carries on Exploring.
