Modeling And Optimization Of Power Plant Circulating Water System

Cycle Power Plant pumps as an important auxiliary is a huge power system, its water is generally Turbine Exhaust of 50 -70 times, Meanwhile it is depleting the total electricity generating capacity of 1% -1.5%. Therefore, the study of the development of the circulating water system and the optimal mode of operation, for saving electricity plants, improve the operation of the plant is of great economic significance.Circulating water system optimization objective function of the operation of the steam turbine generating capacity and circulating pump and the balance of power consumption reached maximum. Therefore, in order to know turbine output and vacuum relations. Vacuum pump with the flow. Therefore, the study circulating pump optimal mode of operation and optimum vacuum is going to search, find out the optimal blade angle.In this paper, based on the actual data for the plant, the mathematival model of a power plant (do not use high-voltage inverter) condenser vacuum system is established and hence the sqp algorithm is introduced to seek the solotion of the optimal strategy. As we know, with the development of variable frequency technology as well as the intelligent optimization theory, the establishment of the model of the circulation pump system with frequency converter has been possible. As to the model of the circulation pump system ,we used the genetic algorithm which is currently more mature overseas and we calculated the optimal solution.
