【摘要】：隨著經(jīng)濟(jì)的發(fā)展和社會的進(jìn)步,能源問題越來越受到世界上各個(gè)國家的關(guān)注,已逐漸成為衡量國家綜合競爭力的一項(xiàng)重要指標(biāo)。電力能源作為國家的重要能源之一,為國家經(jīng)濟(jì)的發(fā)展、科技的進(jìn)步、社會的穩(wěn)定等方面做出了重要貢獻(xiàn)。電網(wǎng)工程作為電力能源使用的基礎(chǔ),對服務(wù)經(jīng)濟(jì)社會有著不可忽略的作用。而隨著電力消費(fèi)量的不斷增加,對供電線路的要求越來越高,為減少長距離供電過程中的損耗,越來越多的國家增加了高電壓及特高電壓線路的研究。 近年來,我國電力負(fù)荷增長速度較快,超高壓輸電工程逐漸出現(xiàn)了輸送能力不足、輸電走廊緊缺、遠(yuǎn)距離大容量輸送困難、環(huán)保壓力較大的問題。同一般輸電線路相比,特高壓輸電線路體系具有電壓等級高、涉及面廣、跨度較大和海拔高等特點(diǎn),這也間接增加了特高壓輸電塔線體系建立的難度。本文結(jié)合實(shí)際工作,以哈密-鄭州±800kV直流輸電線路工程為例對特高壓輸電工程的效益進(jìn)行了研究。 在介紹了特高壓輸電工程的特點(diǎn)、優(yōu)勢及其存在的問題和對策后,本文從經(jīng)濟(jì)效益、環(huán)境效益、社會效益和電網(wǎng)效益四個(gè)一級指標(biāo),盈利能力、償債能力、用戶滿意度等12個(gè)二級指標(biāo),凈現(xiàn)值率、投資利潤率、投資回收期等23個(gè)指標(biāo)構(gòu)建了特高壓輸電工程綜合效益評價(jià)指標(biāo)體系。然后對后評價(jià)方法進(jìn)行了研究并選擇了模糊層次綜合評價(jià)法,對特高壓輸電工程的效益進(jìn)行了分析研究。根據(jù)分析結(jié)果我們發(fā)現(xiàn)該工程的效益介于一般和較好之間,其中社會效益水平較稍微接近于較好,經(jīng)濟(jì)效益和電網(wǎng)效益比一般稍微好,各方面效益均不理想。需建立廣泛的全國性特高壓輸電網(wǎng)絡(luò)線路。
[Abstract]:With the development of economy and social progress, the problem of energy has attracted more and more attention in various countries of the world, has gradually become an important indicator to measure the comprehensive competitiveness of the country. The electric energy is one of the important national energy, for the development of the national economy, progress of science and technology, make an important contribution to social stability and so on. As a basis for power grid engineering energy use, there can not be ignored for economic and social services. And with the increasing of power consumption, the power supply line of the increasingly high demand, in order to reduce the loss of long distance power supply in the process, more and more countries increase the research of high voltage and extra high voltage line.
In recent years, China's electric power load faster, UHV transmission engineering has gradually appeared insufficient transmission capacity of transmission corridor, long distance and large capacity shortage, difficulties in transportation, environmental pressure. Compared with the general transmission line, UHV transmission line system with high voltage level, involving a wide range, large span and high altitude, which also indirectly increases the establishment of UHV transmission tower line system. This paper combined with the actual work, studied in Hami - Zhengzhou 800kV HVDC line project for the benefit of UHV transmission project.
In the characteristics of UHV transmission technology, advantages and existing problems and countermeasures, this article from the economic benefits, environmental benefits, social benefits and power efficiency of four first level indicators, profitability, solvency, customer satisfaction 12 two level index, rate of net present value, the investment profit rate, investment payback period 23 indicators to build a comprehensive evaluation index system of UHV transmission project. Then studies and choose the fuzzy hierarchy comprehensive evaluation of post evaluation method of UHV transmission engineering efficiency were analyzed. According to the analysis results, we found that the benefits of the project between good and average level of social benefits, including is a little closer to the good economic efficiency and the benefit is slightly better than the general power grid, the benefits are not ideal. Need to establish a comprehensive national network of UHV transmission lines.
