【摘要】：進入21世紀(jì)，，隨著我國國民經(jīng)濟的快速發(fā)展和國民生活電氣化水平的不斷提升，我國的電力需求有了大幅度明顯增長。我國電力基礎(chǔ)建設(shè)投資也隨電力需求的增長逐年大幅度增加。國家電網(wǎng)公司編報的“十一五”電網(wǎng)規(guī)劃及2020年遠景目標(biāo)報告顯示,“十一五”期間國家電網(wǎng)公司電力基礎(chǔ)建設(shè)總投資將達到9000億元。并且隨著“十二五”步伐的全面推進，我國迎來了經(jīng)濟發(fā)展的重要機遇。而經(jīng)濟的穩(wěn)定、可靠、長期發(fā)展，離不開電力的強大支持。為了滿足經(jīng)濟發(fā)展對電力的強大需求，全國電網(wǎng)都在加大新建、擴建力度。就電力系統(tǒng)而言，變電站更是其重要的組成部分，它的建設(shè)管理的全過程是電力系統(tǒng)工程管理的一個縮影。 本篇論文以變電站建設(shè)成本控制為切入點，從長期以來，我國電力系統(tǒng)對變電站工程項目的成本控制的現(xiàn)狀，即現(xiàn)階段電力工程成本管理模式為全過程成本控制，其僅注重建設(shè)期成本，而沒有考慮項目在竣工后的生產(chǎn)運行階段的運營、維護、報廢成本或考慮比較粗略，導(dǎo)致許多電力設(shè)備在正常使用生產(chǎn)階段就要進行大修和技術(shù)改造，以及有些工程剛剛竣工就要大修技改。本文引用國內(nèi)外先進的電力工程成本管理經(jīng)驗，以分析我國電力工程成本管理存在的諸多問題為基礎(chǔ)，將全壽命周期工程成本管理思想和理念引入到我國的電力工程成本管理中去，重新劃分我國電力工程成本管理階段，以本溪66KV何家變電站工程項目為例，綜合分析該工程項目全壽命周期成本以及全壽命周期各階段影響工程項目成本的因素�；诔杀绢A(yù)測和成本風(fēng)險分析方法，借助歷史數(shù)據(jù)，建立數(shù)學(xué)模型，推測損失值，分析工程項目全壽命周期存在的成本風(fēng)險，并就具體問題，提出解決措施。做好變電站工程項目全壽命周期的成本控制和成本風(fēng)險管理。為全壽命周期工程成本管理模式在我國電力行業(yè)的實行打下堅實的基礎(chǔ)。大量事實表明，項目未來所產(chǎn)生的這些成本，占據(jù)變電站工程項目總成本很大比例。因此，變電站工程項目成本管理需考慮全壽命周期成本控制，建立一個完善的變電站成本管理機制，實現(xiàn)變電站全壽命周期的經(jīng)濟優(yōu)化。
[Abstract]:In the 21st century, with the rapid development of China's national economy and the continuous improvement of the level of electrification of national life, The electricity demand of our country has increased by a large margin, and the investment in electric power infrastructure has also increased greatly with the increase of power demand year by year. The 11th Five-Year Plan of the State Grid Company and the Vision report for 2020. The report shows that the State Grid Corporation's total investment in power infrastructure construction will reach 900 billion yuan during the 11th Five-Year Plan period. And with the overall promotion of the 12th Five-Year Plan, China has ushered in an important opportunity for economic development. However, the stability, reliability and long-term development of the economy cannot be separated from the strong support of electricity. In order to meet the strong demand for electricity from economic development, the national power grid is expanding and building. As far as power system is concerned, substation is an important part of it, and the whole process of its construction management is a microcosm of power system engineering management. This paper takes the substation construction cost control as the breakthrough point, from the long-term, our country electric power system to the substation project cost control present situation, namely the present stage electric power engineering cost management pattern is the entire process cost control. It only pays attention to the cost of construction period, but does not consider the operation, maintenance and scrapping cost of the project in the production and operation stage after completion, which may result in many electric power equipment having to undergo overhaul and technical transformation in the normal use and production stage. And some projects will be overhauled just after completion. This paper cites advanced experience in cost management of electric power engineering at home and abroad, based on the analysis of many problems existing in the cost management of electric power engineering in China. The whole life cycle project cost management is introduced into the power engineering cost management of our country, and the phase of power engineering cost management in our country is reclassified. Taking Benxi 66KV Hejia substation project as an example, The cost of the whole life cycle of the project and the factors affecting the cost of the project in every stage of the whole life cycle are analyzed synthetically. Based on the methods of cost prediction and cost risk analysis, a mathematical model is established with the help of historical data, and the value of loss is estimated. To analyze the cost risk of the whole life cycle of engineering project, and to solve the specific problems, The solution is put forward. The cost control and cost risk management of the whole life cycle of the substation project are done well. It lays a solid foundation for the implementation of the cost management mode of the whole life cycle project in the electric power industry of our country. A large number of facts show that, The future cost of the project accounts for a large proportion of the total cost of the substation project. Therefore, the cost management of the substation project should consider the life-cycle cost control and establish a perfect substation cost management mechanism. The economic optimization of substation life cycle is realized.
