Research on Modeling and Parameter Identification of Circulating Cooling Water System

Firstly, the hydraulic models of the main components of the circulating cooling water system and the pipe network system were established, and solved using Newton's iterative method. Furthermore, considering the influence of the external environment and the temperature of the circulating water on the operating characteristics of the system, the thermodynamic models of the cooling tower and plate heat exchanger were established, and they were linked with the hydraulic model of the pipe network system to obtain the overall model of the circulating cooling water system and the rationality of the modeling was verified. For the specific circulating cooling water system, the adaptive differential evolution algorithm is used to identify the mechanism parameters in the overall model of the pipe network system to improve the accuracy of the model. Simulation results show the effectiveness of the method used.
