摘　　要：针对苏尔寿系列PLC控制系统触摸屏近年来长期使用已多次出现问题,产品已经停产,且触摸屏故障频繁,无法更换。同时控制系统触摸屏软件组态繁琐,且无历史趋势等难题,以神华某电厂1号机组的旁路及旁路控制系统系统技术改造为背景,采用OVATION控制系统,将原旁路控制系统移入DCS系统,双冗余CPU控制、搭建与建设整个流程实现了设备的最优更换,优化控制策略。该技术成功应用于神华某电厂,保证了机组的期稳定运行,提高了机组控制系统智能化水平,降低了维修强度,具有较好的技术经济性。Aimed at the many problems of the touch screen of PLC control system of Sulzer series in recent years, the products have been discontinued, because of the frequent breakdowns, the touch screen cannot be replaced. And there are many problems such as touch screen control system software configuration, and none of the historical trend. This paper takes system technical transformation of the side road and control system of side road of Unit 1 in a power plant of Shenhua as the background and uses OVATION control system to dislodge the control system of side road into DCS system. The whole process control, building and construction by the dual redundant CPU realizes the optimal replacement and optimizes the control strategy. This technique is successfully applied in a power plant of shenhua, and it guarantees the stable operation of the unit, raises the intelligent level of the unit control system, reduces the intensity of maintenance and gets good technical economy.
