An optimization method for the peak cooling system of an air-cooled unit

Abstract

The invention relates to an optimization method for a peak cooling system of an air cooling unit, and belongs to the technical field of air cooling unit design of power stations. According to the known conditions of an air-cooling island characteristic curve, a turbine micro-increase power curve, environmental meteorological parameters, the surplus amount of water resource, the cost of electricityof a power plant, equipment price parameters of the air cooling unit and the like, and by calculating economic data such as equipment investment and operating cost, important equipment parameters such as optimized peak condenser area, circulating water volume, and mechanical tower configuration are determined. The optimization method for the peak cooling system of the air cooling unit is more consistent with application, the important equipment parameters such as the optimized peak condenser area, the circulating water volume, and the mechanical tower configuration are finally determined, theequipment configuration is more reasonable, and the unit operation economy is good.

Description

technical field [0001] The invention relates to an optimization method for a peak cooling system of an air-cooling unit, and belongs to the technical field of design of an air-cooling unit in a power station. Background technique [0002] At present, in my country's "Three North" regions, large-scale thermal power generation units mostly use air-cooled units. Due to the low cooling efficiency of the air-cooled island in the air-cooled unit, the coal consumption of the air-cooled unit is relatively high. In response to the national call for energy conservation and emission reduction, many power plants have carried out Peak cooling technical improvement project. Peak cooling in summer [0003] The peak cooling system mostly adopts the technical scheme of "power tower + circulating water pump + condenser". The technical parameters of the three major equipment in this technical scheme will directly affect the performance indicators of the unit. Although the cold end optimizatio...

Problems solved by technology

Although the cold end optimization calculation of air-cooled units and wet-cooled units has been very mature, the optimization method of this "dry-wet combined" unit with a peak cooling system is still blank, which brings a lot of inconvenience to the engineering design and implementation

At present, there is no proper optimization calculation method, resulting in unreasonable equipment configuration and poor unit operation economy
