【摘要】：近幾年來,一系列突發(fā)事件的發(fā)生給我國電網的安全運行造成了極大的危害。電網企業(yè)在面對特大自然災害和突發(fā)事件時,如何保障電力應急物資的及時供應,在最短的時間內修復供電線路的暢通,恢復災區(qū)供電系統(tǒng)的正常運行,對于減災、防災和把災害、事故損失減到最低,具有重要的現(xiàn)實意義。作者對電力應急物資配送進行科學的規(guī)劃設計,以期望可以有效地保障事故線路的及時修復和電網整體安全性的提升。 本文在對國內外應急物流和電力應急物資等相關問題的研究現(xiàn)狀進行概述的基礎之上,分析歸納出了我國電力應急物資調配的獨特之處,闡明了電力應急物資儲備要求和電力應急物資需求的相關理論,并結合我國電網公司的實際情況,重點介紹了我國電力物資儲備中心和儲備庫的分布情況。通過運用三角模糊數(shù),引入模糊速度、模糊時間區(qū)間等變量,提出了電力應急物資保障率的求解函數(shù)。文章綜合考慮電力應急物資的時間價值和經濟效益,建立了電力應急物資運輸保障率最大和運輸成本最小的多目標配送優(yōu)化模型。并通過構建電力應急物資配送網絡、區(qū)域劃分、需求分解和分區(qū)域線路選擇的思想來簡化模型求解。為了保證物資調配的及時到位,文中運用了需求分解的思想,每個需求點的整車物資實行點對點直接配送,需求點余貨物資采取拼湊整車的方式進行配送,有效降低了電力應急物資的運輸成本。為了降低余貨物資調配車輛路徑選擇的復雜度,作者建立了帶有約束的條件的區(qū)域劃分模型,通過對調配網絡區(qū)域劃分,然后再分區(qū)域進行線路選擇的辦法,并采用改進的遺傳算法實現(xiàn)區(qū)域內線路的快速選擇。 最后,文中根據(jù)電力應急調配網絡構建、物資區(qū)域劃分、需求分解和區(qū)域內物資調配線路選擇的思想方法,運用實際算例對模型進行了求解說明。
[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.
