灰色系统理论在离心式压缩机热力性能在线预测中的应用

The Application of Grey System Theory in On-line Predicting of Centrifugal Compressor Thermal Performance

通过灰色系统模型的建立 ,对离心式压缩机的热力性能在线预测模型进行了分析 ,运用灰色理论 ,对多变效率及轴耗功率的趋势预测进行了研究 ,误差分析证明了这种模型的建立具有相当高的精度 ,该模型的实用性也在“离心式压缩机热力性能在线监测及性能评估系统”的使用中得到证实。

By the building of Grey System Module,the analysis for the thermal performance on-line predicting of the centrifugal compressor has been carried out.The thermal performance trend for compressor stage or the whole efficiency and shaft power has been studied on the basis of grey theory.Error analysis states that the building of the module is accurate.By successful running of 'Centrifugal Compressor Thermal Performance On-line Monitoring And Evaluating System'in some plant,the module practicality is proved which is part of the 'On-line System'.
