Research On Optimal Operation Of Feed Water Pumps In Power Plant

In this thesis the actuality and development of optimal operation of the feed water pumps in power plant in China and abroad is summarized, and expounds it has great significance to increase unit-economy by feed water pumps'optimal operation in power plant. This thesis explains feed water pump's energy-saving principle briefly and curve fitting and least squares also described in this paper. Basic on the variable load operation, starting from the analysis of the energy saving principles, a set of off-line optimal operation analysis system is designed by a visible programming language Visual Basic 6.0. Through to curve fitting of feed water pump and pipe line system, operation analysis, economic analysis, the system can give several optimal operation modes. The software can indirect the operation in site. It also laid a foundation of development of on-line system.
