“…Boiler, steam turbine, and generator are called the three main equipment in thermal power plants [5][6][7][8][9][10][11], other auxiliary equipment of production system includes the coal delivery system, the chemical treatment system of water, and the slurry discharge system, etc. These systems cooperate with the main system to complete the task of electricity production [12][13][14][15]. To ensure these equipment to operate normally, it's a necessary work to fully consider the periodical repeat features of thermal process of power plants [16][17][18][19] when modelling the thermal process based on thermal state data of machine units, thereby promoting the units to develop toward the direction of multi-parameter, multi-modal, and highly automated.…”

To keep the main system and the auxiliary equipment of production system of thermal power plants operating normally, it's a necessary work to fully consider the periodical repeat features of thermal process when modelling the thermal process based on thermal state data of machine units. Since most equipment in power plant work in an electromagnetic coupling environment, a too high ambient temperature will affect the safe operation of units, so when studying the dynamic features of multi-modal thermal process of power plants and their soft environment, the temperature distribution features of multimodal thermal process should be classified. To solve these questions, this paper established a model for the coupled temperature field during multi-modal thermal process and studied its analytical solutions. At first, this paper proposed a multi-modal modelling method for solving the distribution features of coupled temperature during multi-modal thermal process, the method can quickly determine the optimal number of local models of multimodal thermal process of power plant units while reducing the computational load of the coupled temperature field model. Then, this paper introduced an improved niche method into the basic cross-entropy optimization algorithm and used it to solve the layout optimization problem of coupled temperature field during multi-modal thermal process. At last, the validity of the proposed method was verified by experimental results.
