Abstract: In view of the high heat energy consumption of a power plant, the system model of 200 MW and 300 MW combined unit was built by EBSILON simulation software, and the optimal operation mode of the unit was obtained, which effectively alleviated the problems of large energy consumption and high operation cost of combined unit. In simulation process, different distribution of heat and power load was calculated. When the proportion of heat and power load of 300 MW unit changed, the corresponding change curves of the total coal consumption of the unit and the standard coal consumption for generation power were obtained. The simulation results showed that, the economy and safety of the unit were the best when the generating capacity of 300 MW unit was 250 MW to 280 MW. The results provided theoretical support for determining the optimal heat and power load distribution of combined unit, and achieved the goals of energy saving, emission reduction and energy consumption reduction.

Key words: power plant simulation, combined heat and power, heat supply with extraction steam, heat and power load, distribution optimization
