Based on the matter-element theory,the matter-element model for the operational condition of steam turbines was constructed,and an extensive evaluation method is proposed.The correlation functions and correlation degree were introduced,and the correlation degree was used for qualitative and quantitative evaluation for the operational condition of the steam turbine.The practicability of the method is proved through an example.Research results show that the method can quickly and effectively discriminate the steam turbine′s operational conditions,and thus provides support for decision-making of condition-based maintenance.
