| 摘 要： | 在建立汽轮机运行状态评价指标的基础上,提出了一种可拓评价方法.基于可拓学的物元理论,建立了汽轮机运行状态的物元模型,引入可拓集合中的关联函数与关联度,由综合关联度的大小对汽轮机运行状态进行定性和定量评价,并开发了基于SIS实时/历史数据平台的汽轮机运行状态评价系统,最后通过实例验证了该方法的实用性.研究结果表明,该方法能快速而有效地识别汽轮机运行状态,从而为状态维修决策提供科学的依据.

| Abstract: | On the basis of establishing indexes for condition evaluation on large-sized steam turbine,an extensible method was proposed.This method was based on matter-element theory,established an matter-element model for appraising the operating status and used a group of extensible correlation functions to calculate the correlation between the steam turbine operating state parameters and various status grades.Also,a condition evaluating system has been developed based on SIS real-time/history data platform.Finally,... |
