基于FBWM-TOPSIS的配电网检修关键线路识别方法OACSTPCD
Maintenance Critical Line Identification Method Based on FBWM-TOPSIS in Distribution Network
在有限的资源和时间背景下,设备检修是保持系统稳定运行的有效方法.为了高效地分配检修资源,应该首先确定系统中最关键的设备,即那些发生故障会造成较大后果的设备.首先提出了一种新的多准则决策方案来识别配电网中的关键线路,与以往基于层次分析法不同,采用最优-最劣法,根据专家的知识和判断求得系统可靠性指标的权重.此外,在传统最优-最劣法中引入模糊理论克服专家判断和决策中普遍存在的不确定性.最后,利用逼近理想解排序法对IEEE14节点配电网线路进行检修优先排序.所提的方法可以更快、更准确地确定系统检修的优先顺序.
Under the background of limited resources and time,equipment maintenance is considered as an effective way to maintain the stable operation of the system.In order to allocate maintenance resources efficiently,the most critical equipment in the system should be identified first namely those that will cause significant consequences if they fail.Firstly,a new multicriteria decision-making(MCDM)scheme was proposed to identify the critical lines in the distribution network.Different from the previous analytic based hierarchy process,the best-worst method(BWM)was adopted to obtain the weight of the system reliability index according to the knowledge and judgment of experts.In addition,the fuzzy theory was introduced into the traditional best-worst method to overcome the general uncertainty in expert judgment and decision making.Finally,the technique for order preference by similarity to an ideal solution technology was used to prioritize the maintenance of IEEE14 distribution network lines.The proposed method can determine the priority of system maintenance more quickly and accurately.
