摘要
在建立凝汽器运行状态评价指标的基础上,针对评价指标的多样性及模糊性,提出一种以物元模型和可拓关联函数为基础的凝汽器运行状态的可拓评价方法。基于可拓学中的物元理论,建立起凝汽器运行状态评判的物元模型,并利用一组可拓关联函数计算凝汽器运行的状态参数和状态等级之间的关联度,由关联度的大小对凝汽器状态进行定性和定量评价,最后通过实例验证了本方法的实用性。研究表明,该方法能快速而有效地识别凝汽器运行状态,为凝汽器运行状态的评价提供一种新的途径。
On the basis of establishing indexes for evaluation of the operating states of condensers,presented was an extensible method for the above evaluation in the light of diversity and fuzziness of the evaluation indexes.The proposed method was based on an object-element model and extensible correlation functions.In combination with currently available literature and extension theories,the object-element model for appraising the operating status of a condenser was established and a group of extensible correlation functions was used to calculate the correlation between the condenser operating-state parameters and various status grades.Then,based on the magnitude of the correlation in question,a qualitative and quantitative evaluation of the condenser operating state was conducted.Finally,the practicability of the method under discussion was verified by a specific case calculation.The research findings show that the method in question can quickly and effectively identify the operating state of a condenser,thus providing a new approach for the latter's evaluation.
