The anti-surge control of the standby fan of the 1.8 million tons/year ARGG unit of Daqing Refining and Chemical Company adopts the TS3000 system of TRICONEX of the United States. This paper focuses on the analysis of the anti-surge control program of the axial flow fan using the advanced control concept, that is, the source program written in the LAD ladder logic language in the triple TRICON system is moved to the TPS system of HONEYWELL company, and a complete anti-surge control scheme is established using the RV, RC, Logic and CL programs in the TPS system, and the anti-surge curve is realized using Display Builder. And through a simple simulation of the optimization control of the batch feeding process, the logic control function of Honeywell\'s TPS distributed control system and the functions of other modules are introduced, aiming to develop the advanced control function of DCS. At the same time, the application program is converted into Fuji intelligent regulator PNA3-211 and SIEMENS S7-200 series PLC, and a new emergency control system is completely established to realize the anti-surge control and logical interlocking control of the standby machine. This paper expounds the ideas and specific implementation plans for the transformation and transplantation of application programs in chemical automation professional technology, and explores the practical significance of advanced control technology and optimization technology in practical applications. The control system of the three units (axial flow fan, smoke machine, main motor) of the 1.8 million tons/year ARGG device of Daqing Refining and Chemical Company is the TS3000 control system of TRICONEX, as shown in Figure 1. Since its commissioning in 1998, it has been running smoothly, but since 2002, the control system has frequently experienced burning and jamming (see the attached table). 18 various types of jamming parts have been replaced, which seriously threatens the safe production of the device. In this regard, the leaders of the Refining and Chemical Company attach great importance to it, and have organized professional technical analysis meetings many times, and organized instrument and electrical technicians to conduct detailed inspections of the entire system. At the same time, they contacted Beijing Design Institute, Shaanxi Blower, American TRICONEX Company, ELLIOTT Company, and the construction unit Sinopec No. 1 Company, and held a three-day professional analysis meeting in June 2000 to analyze the cause of the failure. All units agreed that the grounding system and power supply system should be inspected, tested and rectified. A thorough overhaul was carried out during the plant shutdown and maintenance in 2002, which cost about RMB 300,000.
