摘要
针对电厂设备冷却水等冷链系统的设计余量大、冬季供水温度低等问题,提供了一套创新设计方法,该方法可用于在总体设计阶段确定系统配置和运行方案。首先基于系统热平衡的基本原理,建立热工评估模型;基于满足安全和运行条件下尽可能提高经济性的指导思想,建立经济性评估模型;然后基于优化设计的基本原理,开发多目标优化算法及分析程序;最后应用上述程序处理系统设计中的多目标优化问题,最终实现系统方案评估。给出了华龙一号设备冷却水系统优化评估结果,使电厂经济性明显提高;突破传统过于依赖设计经验、定量分析不充分的单线设计流程;在多专业、多变量设计方案调整及参数优化时,采用软件决策辅助人工决策,缩短设计耗时、提高准确度。
Aiming at the problems of large design margin and low winter supply water temperature of cold chain systems such as equipment cooling water in power plants,an innovative design method is provided,which can be used to determine the system configuration and operation scheme in the overall design stage.Firstly,based on the basic principle of system heat balance,a thermal evaluation model is established,and an economic evaluation model is established based on the guiding ideology of improving economy as much as possible under safety and operating conditions.Then,based on the basic principle of optimization design,the multi-objective optimization algorithm and analysis program are developed.Finally,the above program is used to deal with the multi-objective optimization problems in the system design,and finally the system scheme evaluation is realized.The optimization evaluation results of the cooling water system of HPR1000 equipment are given,which significantly improves the economy of the power plant.It breaks through the traditional single-line design process which relies too much on design experience and is subject to insufficient quantitative analysis.In the adjustment of multi-discipline and multivariable design scheme and parameter optimization,software decision-making is used to assist manual decision-making to shorten the design time and improve the accuracy.
