中文摘要:
      针对检修决策中难以兼顾成本和长期效益的问题,提出了一种基于设备役龄回退分析的预测性检修决策方法。首先,基于设备现况计算检修前的故障率。其次,基于设备役龄回退分析方法预测检修后的故障率。再次,依据设备检修前后的故障率,分别计算检修前后的全生命周期成本变化量和检修方式的费效比。最后,分别按可靠性优先、经济性优先和费效比优先的原则遴选最佳检修策略。实例效果表明,本文算法所得检修策略可兼顾成本和长期效益的矛盾,显著降低设备运行风险,提高电网长期效益。
英文摘要:
      According to the maintenance cost and long-term benefits, this study proposes a predictive maintenance decision method based on the service age. Firstly, the failure rate is calculated before maintenance based on the equipment status. Secondly, the failure rate after overhauling is predicted based on equipment service age reduction. Thirdly, According to the failure rate, the degree of EENS, the change of LCC and the cost-effectiveness ratio of maintenance are calculated, respectively. Finally, the best maintenance plan is chosen on the basis of the principle of reliability priority, economy priority and cost-effectiveness priority. The result of the example shows that this algorithm reduces the risk and improves the benefit.
