Abstract

The invention discloses a method for optimizing the volume of main equipment of a secondary circuit of a floating nuclear power station. The method comprises the following steps: (1) establishing a mathematical model for structural design of the main equipment of the secondary circuit; (2) selecting optimization parameters; (3) establishing a target function; (4) establishing constraint conditions; (5) establishing a secondary circuit thermodynamic scheme; (6) carrying out heat balance calculation; (7) calculating the total volume of the equipment to obtain a target function value; (8) optimizing parameters, namely optimizing the optimized parameters through an improved particle swarm algorithm, calculating the particle speed, obtaining the position of the next generation of particles, andupdating individual optimal particles and global optimal particles; and (9) repeating the steps (6)-(8) until the preset number of iterations is completed, and taking a group of optimization parameters enabling the target function value to be minimum as an optimal solution. The method provided by the invention ensures that the devices can be matched with each other when the structures of the devices are designed; and the adopted improved particle swarm algorithm can achieve global optimization.

Description

technical field [0001] The invention relates to an equipment volume optimization method, in particular to a volume optimization method that is oriented to the application of the secondary circuit of a floating nuclear power plant and can be applicable to the main equipment of the secondary circuit. Background technique [0002] Floating nuclear power plants refer to mobile nuclear power plants built on floating platforms, which have obvious advantages in areas such as power supply and seawater desalination in areas without grids. The secondary circuit system is an important part of the pressurized water reactor nuclear power plant. Its main function is to convert the heat generated and transferred by the reactor and the primary circuit system into the mechanical energy required for ship navigation, and to produce electrical energy and fresh water. The space occupied by the secondary circuit of the floating nuclear power plant directly affects its mobility and flexibility. Th...
