The invention relates to a steam turbine layout design optimization method in a steam power system containing complete steam-water circulation, and the method comprises the steps: determining the performance characteristic parameters of all equipment in the steam power system and the process parameters of the steam power system, and carrying out the flow simulation of the steam power system; generating an alternative scheme of the steam turbine layout according to the production process; then generating a mixed integer linear mathematical model according to the mass balance equation and the energy balance equation of each device, the overall energy balance equation of the steam power system, a steam turbine layout scheme selection equation and a target function equation; a steam turbine layout scheme is selected according to the optimal solution result of the mixed integer linear mathematical model; correcting the performance characteristic parameters of each device and the process parameters of the steam power system at the same time; finally, the steam power system with the determined steam turbine layout structure is subjected to process simulation again, and the overall performance index of the steam power system is verified. The optimization method is more suitable for a real scene.
Description
technical field [0001] The invention relates to the field of steam power, in particular to a steam turbine layout design optimization method in a steam power system with a complete steam-water cycle. Background technique [0002] Steam power system is an important part of large-scale process industries such as petrochemical, metallurgy, pharmaceuticals, and food, and is a major energy consumer within an enterprise. Large-scale process industrial enterprises have a huge demand for steam and electricity, and the construction investment and operation costs of the steam power system are extremely high, and the environmental pollution is also relatively large. With the increasingly tense supply of fossil energy and the increasing efforts of the country to protect the environment, large-scale process industrial enterprises are paying more and more attention to the energy efficiency of steam power systems. Considering the huge volume of the steam power system, improving the steam ...
