摘　　要：由于电站锅炉是一个庞大、复杂系统,所涉及的相关参变量繁杂,很容易引起锅炉建模过程的"维数灾"的问题。利用国际通用软件SPSS,以提搞锅炉效率作为目标,对实际对象中的各参数通过共线性诊断和主成分分析等操作,得到关于锅炉效率的多元一次回归方程。并在充分遵循实际情况的基础上,尽可能地缩小模型中参数的个数,达到降维目的。实验结果表明,将锅炉效率为目标建立的新模型与已有的机理模型结果进行比较,建立的锅炉效率预测模型与机理模型结果相吻合。The power plant boiler is a large and complex system,the correlation parameter involved in the boiler is complex,and can easily lead to the problem which is called ＂curse of dimensionality＂ in the boiler modeling process.This text uses the boiler efficiency as target,and treats each parameter of the actual object by logistic and principal component analysis and other operations through the international common software SPSS,to get the multiple regression equation with regard to the boiler efficiency.And in the situation of full compliance to the actual,the establish meat of the model narrows the number of parameters as much as possible to achieve the purpose of reducing dimension.In the end,the new model which uses the boiler efficiency as target will be set up,and the results of the new model tallies with that of the existing mechanism model.
