隔离型热管换热节能系统稳态的判定

针对系统在线稳态优化中对关键输出变量相对稳态的判定要求,基于假设检验提出了一种样本数据稳态判定方法,该方法能实现隔离型热管换热节能系统中数据稳态判定.同时,利用现场数据进行实验研究,所选数据总体服从正态分布,通过判断样本数据的方差变化完成数据稳态判定,得到优化周期大于4 min的结论.

Determination of Steady-state of an Isolated Heat-pipe Heat Exchange Energy Conservation System

For the steady-state identification of the key variables in the steady-state optimization,a determination method was proposed for the steady-state identification of sample data based on the hypothesis testing.The method could realize the data steady-state identification of the isolated heat-pipe heat exchange system.Then,experiments were carried out by the practical data with normal distribution characteristics.The data steady-state was determined by judging the change of sample variance.Finally,it was found that the optimization cycle must be greater than 4 minutes.
