基于西门子DEH优化的机组运行状态模糊风险评价
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
