Research on optimal operation of mainpipe scheme feed pumps set

Abstract

Abstract: Adopting the Apros 5.04 advanced procedure simulation support system, taking the feed water pipes network system of a thermal power plant as research object, through the modeling, which is based on the graphical configuration provided by the system, and the automatic simulation calculation, the model of the water feed pipe network was developed. The parameters calculated by using the model were analyzed; the operation characteristics of the water feed system was grasped; the power consumptions under different feed water pump combination were obtained, and its influence on the feed water flow distribution of the high pressure heater was determined; the optimized economical operation mode was realized. The realization of this project will greatly enhance the operation level of the feed water system of whole plant and the equipment monitoring level, will perfect the examination and the analysis of the economical index, and it is of important significance for the security and the economic efficiency of the units of whole plant. 

Key words: main-pipe scheme, feed water system, simulation, high pressure heater, feed water flow distribution, combination of feed water pumps
