摘　　要：结合某电厂125 MW机组控制系统的改造,提出运用分散控制系统改造老电厂控制系统的措施,并应用直接能量平衡原理进行协调控制系统的设计。介绍了主要模拟量控制系统的设计要点和改造后的控制品质,提出了一些尚待改进的方面。Combined with the retrofit of the control system for 125 MW unit in a power plant, a distributed control system （DCS） was applied instead of the existing control system in the power plant and the principle of direct energy balance （DEB） was used for the design of coordinated control. Some key points of control system design for major analog quantity and the quality control after retrofit have been described and some aspects of pending improvement have been put forward.
