Abstract:
Taking a 600MW indirect air-cooled unit as an example, thermal calculation model of the condenser and numerical calculation model of air-cooled tower are established, respectively. In order to obtain operating characteristics of the indirect air-cooled system under off-design condition, 49 numerical simulations were carried out with the coupled method according to orthogonal experimental design. Based on least square support vector machine, a fast calculation model for back pressure which reflects operating characteristics of the unit is established based on the results of numerical computation. By this model, the effects of ambient temperature, crosswind speed and thermal load on back pressure of the unit are obtained under all working conditions. Combining the accuracy of numerical simulation based on mechanism and excellent generalization of least square support vector machine, this model has fast calculation speed and provides a continuous and quantitative guidance for the economic and safe operation of the unit.
