摘要

基于西门子公司的数字电液控制系统(DEH)故障树

结合机组运行特点

建立了模糊风险评价模型

并对DEH优化前、后的机组运行状态进行模糊风险评价

验证了DEH优化的可行性

评估了DEH优化后机组运行的可靠性、经济性

以降低机组的运行风险。

Abstract

On the basis of the Siemens digital electro-hydraulic control system(DEH)fault tree

and combining with the unit operation characteristics

a fuzzy risk assessment model was established.Moreover

fuzzy risk assessment before and after the DEH optimization was carried out for the unit operation status.Thus

the feasibility of the DEH optimization was verified

the reliability and economy of the unit operation after the DEH optimization was evaluated

and the risk of the unit's operation was reduced.
