Abstract: Aiming at the low automation, backward management and difficulty in information integration existing in thermal power plant fuel management, based on the case of fuel intelligent management and control system in Hengshan Power Plant, an overall solution is put forward.Fuel intelligent management and control system takes direct control on the basic equipmentl ayers including devices for infrared scanning and automatic identification, unattended weighing, automatic sampling, automatic sample preparation, automatic sample storage and sample pneumatic conveying. Through realtime data acquisition and interaction,the system can take online realtime monitoring on fuel wholeprocess data, so as to achieve successive transfer of “sampling preparationtestmeasuring” data, and improve the degree of automation and intellectualization of fuel management. According to the performance of the scheme, the application and implementation experience of project are summarized, so as to play a demonstration effect for the construction of fuel management and control system of the power plant. The successful implementation of the overall scheme of fuel intelligence will be conducive to improving the fuel management and economic benefits of the power plant, and realizing the transformation from digital power plant to intelligent power plant.
