电厂机电控制系统为实现对电动机的镇流耦合控制大多采用DCS分散控系统。传统的DCS的同步跟踪控制性无法满足实际需要,若是将PLC应用到实际中,将会大大改善这个问题。因此,由于PLC具有编程简单、可靠性强、使用方便等特点,在电厂的机电控制中已经被广泛应用。
Power plant electromechanical control system In order to achieve the coupling control of the motor ballast mostly use DCS decentralized control system. The traditional tracking control of DCS can not meet the actual needs, if the PLC is applied to the actual, will greatly improve this problem. Therefore, PLC has been widely used in electromechanical control of power plants because of its simple programming, strong reliability and easy to use.
