【摘要】:隨著中國經(jīng)濟的持續(xù)發(fā)展,用電需求也持續(xù)增長,承擔電力供應的供電企業(yè)也得到迅速發(fā)展。同時傳統(tǒng)能源的大量消耗,,一方面使我國的傳統(tǒng)能源資源快速枯竭,另一方面也造成了嚴重的環(huán)境污染。現(xiàn)實要求我們必須大力開發(fā)清潔的、可再生的新能源。為了保障新能源的發(fā)展與應用,供電網(wǎng)絡的建設、運營也面臨了許多新的挑戰(zhàn)。其中,不斷提高供電網(wǎng)的智能化,柔性化,以更好地容納分布式能源,成為供電網(wǎng)建設的重要內容之一。這種發(fā)展趨勢,導致供電網(wǎng)的改選項目以及資金投入持續(xù)增長。與此同時,供電企業(yè)強勁的發(fā)展勢頭使得電力投資項目后評價研究具有必要性和緊迫性。 重要建設項目的后評價理論研究已經(jīng)進入了一個相對成熟的階段,然而對于供電企業(yè)技改項目的后評價研究則比較缺乏,目前沒有一套合理、全面、通用的指標體系,并且后評價方法的研究也過多注重靜態(tài)方法,沒有一套科學合理的動態(tài)后評價方法。針對這一問題,本文結合供電企業(yè)自身的行業(yè)特點從項目目標實現(xiàn)程度、技術水平、經(jīng)濟效益、社會效益以及持續(xù)能力五個方面建立供電企業(yè)技改項目完善的后評價指標體系,并且提出了一套基于理想?yún)^(qū)間法的變權物元可拓模型。該模型為體現(xiàn)指標本身的相對重要性和反映綜合評價中諸要素狀態(tài)的均衡性,利用評價對象的主動參與,即變權理論來確定評價指標的權重,同時,運用理想?yún)^(qū)間法來計算待評價對象與評價標準等級的貼進度。最后通過案例分析進行了有效驗證,具有很好的實際應用效果。
[Abstract]:With the sustained development of China's economy, the demand for electricity continues to grow, and the power supply enterprises that undertake the power supply have also developed rapidly. At the same time, the massive consumption of traditional energy resources has on the one hand caused the rapid depletion of traditional energy resources in China. On the other hand, it has also caused serious environmental pollution. The reality requires us to vigorously develop clean and renewable new energy sources. In order to ensure the development and application of new energy sources, the construction of power supply networks, Operation also faces many new challenges. Among them, continuously improving the intelligence and flexibility of the power supply network to better accommodate distributed energy has become one of the important contents of the power supply network construction. At the same time, the strong development momentum of power supply enterprises makes the post-evaluation research of power investment project necessary and urgent. The research on post-evaluation theory of important construction projects has entered a relatively mature stage, however, the post-evaluation research of power supply enterprise technical innovation projects is relatively lacking, and there is no reasonable, comprehensive and universal index system. And the research of post-evaluation method also pays too much attention to static method, and there is not a set of scientific and reasonable dynamic post-evaluation method. In view of this problem, this paper combines the industry characteristics of power supply enterprise from the degree of realization of project objectives, the level of technology, Set up a perfect post-evaluation index system of power supply enterprise technical innovation project in five aspects: economic benefit, social benefit and sustainable ability. A variable weight matter-element extension model based on the ideal interval method is proposed. The model reflects the relative importance of the index itself and the equilibrium of the state of the elements in the comprehensive evaluation, and makes use of the active participation of the evaluation object. That is, variable weight theory is used to determine the weight of the evaluation index, and at the same time, the method of ideal interval is used to calculate the progress of the object to be evaluated and the grade of the evaluation standard. Finally, a case study is carried out to verify effectively, which has a good practical application effect.
