摘要
利用主成分分析法,对某320MW机组的运行状态进行了综合评价。根据分析,得到了主成分分析法的两个主成分,且最大程度地保留了各个原始变量之间的关系,其累计贡献率达到了93.84%。建立了综合评价函数,可对机组的运行状态进行综合评价,具有一定的参考价值。
The operation status of a 320MW unit was comprehensively evaluated using the principle component analysis method. The two principal components were obtained through analysis; the relationship between each of the original variables was greatly retained, and the cumulative contribution rate reached 93. 84% .The comprehensive evaluation function was established, which can comprehensively evaluate the operation status of unit and has certain reference value.
