【摘要】：回顾近十年来,我国境内所发生的严重自然灾害和突发事件给电力行业的稳定运行和生产带了巨大的消极影响。及时供应和配送电力应急物资是电力应急管理工作的重要内容之一,电力企业必须加强电力应急物资迅速供应的能力,做到在尽可能短的时间内将应急点所需求的电力应急物资快捷、安全的送达,及时恢复电力输送以保障受灾断电地区的供电系统能重新正常运转,这对于降低由自然灾害和突发事件所带来的损失有着十分重大的经济和社会意义。本文旨在通过对电力应急物资配送路线进行模型优化分析,以有效地提高电力事故发生后及时恢复线路及设备正常运转的能力,保障电网系统的整体安全性。文章首先分析了国内外现有的有关应急物资和电力应急物资的理论,对研究现状进行概括总结,指出了我国电力应急物资配送的特殊点。其次,本文还阐述了有关电力应急物资储备和需求理论,结合南方电网和国家电网应急物资实际储备状况介绍了现有电力应急物资储备中心分布情况。另外,电力应急物资由于其自身存在价值高、质量大等特性,我们在选择电力应急物资配送路线时,必须考虑灾害造成道路存在运输风险而引起的不同配送道路具有不同可靠性的情形,保证电力应急物资安全高效的配送至各个需求点,因此本文还对道路可靠性的相关理论和以及如何衡量道路可靠性高低进行了简要阐述,并说明道路可靠性对电力应急物资配送路线选择的影响。文章在衡量电力应急物资的经济价值以及时间效益,综合考虑道路可靠性因素的影响,建立总成本最小化目标函数的电力应急物资配送路线选择模型,并通过引入电力应急物资需求点优先级理论和需求分解思想来简化模型求解。为了提高电力应急物资配送的时间效益,文章中通过运用需求分解思想,对整车配送的需求点采取点到点的直接配送方式,对存在余货情况的需求点采取拼凑整车的配送方式,这种整车和余货拼车的相结合的配送方式能有效地降低电力应急物资的运输成本。最后,文中依据所建立的模型以及对电力应急物资需求点的需求量分解的线路选择的思想方法,运用遗传算法思想并使用Matlab工具对模型进行了求解说明以及仿真。
[Abstract]:In the past ten years, the serious natural disasters and emergencies in China have greatly influenced the stable operation and production of the electric power industry. In power supply and distribution of emergency supplies is an important content of power emergency management ability, must strengthen the power supply of the electric power enterprise emergency supplies quickly, be in the shortest possible time will be required for emergency power delivered emergency supplies fast and safe, timely recovery of electricity power supply system to protect the affected area to normal operation, to reduce this caused by natural disasters and emergencies loss has great economic and social significance. The purpose of this paper is to optimize the distribution route of electric emergency materials, so as to effectively improve the ability of line and equipment running in time and ensure the overall safety of power grid system. Firstly, the theory of emergency materials and emergency materials at home and abroad is analyzed, and the research status is summarized. The special points of distribution of electric power emergency supplies in China are pointed out. Secondly, this paper also expounds the theory of reserve and demand for electric emergency materials. Combined with the actual storage status of emergency supplies in China Southern Power Grid and State Grid, it introduces the distribution of existing electric emergency materials reserve centers. In addition, the power of emergency materials because of its characteristics of high value, high quality, we choose the power of emergency logistics distribution route, must consider the disaster caused by the road transport and road caused by different risk distribution with different reliability, ensure safe and efficient emergency power distribution to the various demand points, so this paper related the theory of reliability and how to measure road and road reliability level are briefly described, and illustrate the reliability of emergency material distribution influence road route selection of power. Based on the measured power emergency economic value and time efficiency, considering the influence of road reliability factors, the power of emergency logistics distribution route choice model established to minimize the total cost of the objective function, and through the introduction of electric power emergency demand point priority theory and the demand model to simplify the decomposition idea. In order to improve the power distribution of emergency supplies time, by using the demand decomposition of the ideas in this paper, the demand for the vehicle distribution point to take direct delivery point, take delivery of the goods vehicle together more than the demand, delivery mode is the combination of the vehicle and the vehicle more than goods together can effectively reduce the power of emergency materials transportation costs. Finally, based on the established model and the idea of line selection, which is decomposed by the demand of electric emergency materials, we use genetic algorithm and Matlab tools to solve the problem and illustrate the simulation.
