【摘要】：近几年来,一系列突发事件的发生给我国电网的安全运行造成了极大的危害。电网企业在面对特大自然灾害和突发事件时,如何保障电力应急物资的及时供应,在最短的时间内修复供电线路的畅通,恢复灾区供电系统的正常运行,对于减灾、防灾和把灾害、事故损失减到最低,具有重要的现实意义。作者对电力应急物资配送进行科学的规划设计,以期望可以有效地保障事故线路的及时修复和电网整体安全性的提升。本文在对国内外应急物流和电力应急物资等相关问题的研究现状进行概述的基础之上,分析归纳出了我国电力应急物资调配的独特之处,阐明了电力应急物资储备要求和电力应急物资需求的相关理论,并结合我国电网公司的实际情况,重点介绍了我国电力物资储备中心和储备库的分布情况。通过运用三角模糊数,引入模糊速度、模糊时间区间等变量,提出了电力应急物资保障率的求解函数。文章综合考虑电力应急物资的时间价值和经济效益,建立了电力应急物资运输保障率最大和运输成本最小的多目标配送优化模型。并通过构建电力应急物资配送网络、区域划分、需求分解和分区域线路选择的思想来简化模型求解。为了保证物资调配的及时到位,文中运用了需求分解的思想,每个需求点的整车物资实行点对点直接配送,需求点余货物资采取拼凑整车的方式进行配送,有效降低了电力应急物资的运输成本。为了降低余货物资调配车辆路径选择的复杂度,作者建立了带有约束的条件的区域划分模型,通过对调配网络区域划分,然后再分区域进行线路选择的办法,并采用改进的遗传算法实现区域内线路的快速选择。最后,文中根据电力应急调配网络构建、物资区域划分、需求分解和区域内物资调配线路选择的思想方法,运用实际算例对模型进行了求解说明。
[Abstract]:In recent years, a series of unexpected events have caused great harm to the safe operation of power grid in China. In the face of serious natural disasters and emergencies, how to ensure the timely supply of power emergency materials, how to repair the unimpeded power supply lines in the shortest time, and how to restore the normal operation of the power supply system in the disaster areas, so as to reduce the disaster risk, It is of great practical significance to prevent disasters and reduce the loss of accidents to the minimum. The author carries on the scientific plan design to the electric power emergency material distribution, In order to ensure the timely repair of the accident line and the improvement of the overall security of the power grid, this paper summarizes the current research situation of emergency logistics and emergency materials at home and abroad. This paper analyzes and summarizes the unique aspects of the power emergency material allocation in China, expounds the relevant theories of the reserve requirements of the electric power emergency materials and the power emergency material demand, and combines with the actual situation of the power grid companies in China. The distribution of electric power material reserve center and reserve warehouse in China is introduced emphatically. By using triangular fuzzy numbers and introducing variables such as fuzzy velocity and fuzzy time interval, the function of solving power emergency material guarantee rate is put forward. Considering the time value and economic benefit of electric emergency materials, this paper sets up a multi-objective distribution optimization model, which has the largest transportation guarantee rate and the lowest transportation cost. The solution of the model is simplified by constructing the power emergency material distribution network, regional division, demand decomposition and sub-regional route selection. In order to ensure the timely deployment of goods and materials in place, the paper uses the idea of demand decomposition, each demand point of the vehicle materials are directly distributed point to point, the demand point surplus goods and materials by piecing together the vehicle to carry out the distribution. It effectively reduces the transportation cost of power emergency materials. In order to reduce the complexity of vehicle route selection for surplus goods and materials deployment, the author established a region partition model with constraint conditions. By dividing the distribution network area, and then dividing the area into different areas, the method of route selection was established. And the improved genetic algorithm is used to realize the fast selection of the line in the region. Finally, according to the idea of constructing the power emergency distribution network, dividing the material area, decomposing the demand and selecting the route of the material distribution in the region, A practical example is used to explain the solution of the model.
