Optimization of cold end system of steam turbine

An optimization of the movement characteristic of the cold end system of the steam turbine was conducted from an overall consideration of the condenser and the circulation water pump. An analysis method based on thermodynamics theory that fixes coupling characteristic between the best vacuum and the best circulation discharge of water was proposed. The proposed method was applied to the optimized analysis of the operating mode of the cold end system of a 300 MW unit in a power plant.
