基于TOPSIS法的浓缩倍数优化选择与冷却塔节水研究

Optimization Choice of Concentrated Multiple and Water Saving Research of Cooling Tower Based on TOPSIS

针对电厂循环水系统耗水严重的趋势,为了科学合理的提高浓缩倍数,提出了浓缩倍数与节水关系的指标体系,建立了基于TOPSIS(逼近理想解的排序方法)的冷却塔浓缩倍数与节水的评价模型。通过运用其评价模型,根据TOPSIS的计算结果来对某电厂不同浓度的浓缩倍数优化选择。最后通过实证分析,验证了TOPSIS方法的有效性,得出不同浓度浓缩倍数的优劣顺序,实现对浓缩倍数与节水的优化选择。

According to the power plant circulating water system water consumption serious, in order to increase the concentrated multiple scientific and reasonable. The indices system of the relationship between the concentrated multiple and water conservation was put forward. The model of TOPSIS （technique for order preference by similarity to ideal solution） based on the concentrated multiple and water con- servation of cooling tower was established. By using the evaluation model, according to calculation results of the TOPSIS for different concentrated multiple optimization selection of a certain power plant. Finally, through the empirical analysis, verified the validity of the method of the TOPSIS. The order preference of different concentrated multiple was gained, realized the optimization of concentrated mul- tiple and water saving.
