【摘要】：由于現(xiàn)階段我們國(guó)家的快速發(fā)展,社會(huì)當(dāng)中方方面面對(duì)電力資源的使用范圍逐年擴(kuò)大。國(guó)家在對(duì)大規(guī)模用電量提供支持的同時(shí),同時(shí)也要保證電力資源質(zhì)量與安全性,在這個(gè)過(guò)程中相關(guān)部門就啟用了城市配電網(wǎng)管理系統(tǒng),能夠?qū)Ω鱾�(gè)區(qū)域的電力使用提供綜合的管理,當(dāng)發(fā)現(xiàn)存在與能源傳送相關(guān)的問(wèn)題時(shí),配電網(wǎng)可以及時(shí)的反映并提出相對(duì)的解決措施。本文針對(duì)城市配電網(wǎng)的可靠性進(jìn)行了有關(guān)項(xiàng)目的評(píng)估和管理評(píng)價(jià),以及對(duì)一些相關(guān)問(wèn)題進(jìn)行了相關(guān)的介紹與講解。本文第一章主要進(jìn)行了背景與意義的研究,尤其是近幾年電力負(fù)荷的增長(zhǎng)明顯加快,城市配電網(wǎng)成為了制約城市發(fā)展的"瓶頸",電能質(zhì)量、供電能力和供電可靠性滿足不了用戶的電力需求,通過(guò)目前城市配電網(wǎng)發(fā)展的過(guò)程來(lái)看,進(jìn)一步將國(guó)內(nèi)外現(xiàn)狀進(jìn)行研究對(duì)比,確定了本文研究的內(nèi)容與預(yù)期研究成果;第二章主要是通過(guò)城市配電網(wǎng)可靠性評(píng)估方法及相關(guān)指標(biāo)的計(jì)算,確定可靠性評(píng)估經(jīng)濟(jì)性評(píng)價(jià)的必要性,以及相關(guān)計(jì)算方法適用的經(jīng)濟(jì)基礎(chǔ),主要從給供電公司參考來(lái)考慮,給出了配電網(wǎng)可靠性評(píng)估的概念、方法、模型、基礎(chǔ)數(shù)據(jù)以及指標(biāo)體系;第三章主要是通過(guò)城市配電網(wǎng)架空線路網(wǎng)架和電纜線路網(wǎng)架的介紹,進(jìn)行相關(guān)網(wǎng)架可靠性評(píng)估的前提假設(shè),對(duì)分析結(jié)果進(jìn)行比對(duì)確定影響結(jié)果的變量,利用建立的模型,以典型的配電網(wǎng)接線模式為切入點(diǎn),對(duì)配電網(wǎng)規(guī)劃中的重點(diǎn)內(nèi)容一配電網(wǎng)網(wǎng)架結(jié)構(gòu)進(jìn)行深入經(jīng)濟(jì)技術(shù)分析,在問(wèn)題簡(jiǎn)化的基礎(chǔ)上得出一些較一般的結(jié)論;第四章主要是通過(guò)城市配電網(wǎng)可靠性評(píng)估的經(jīng)濟(jì)性優(yōu)化模型及評(píng)價(jià)研究,確定配電網(wǎng)可靠性的經(jīng)濟(jì)方式,針對(duì)實(shí)際配電網(wǎng)復(fù)雜多樣的特點(diǎn),開發(fā)相應(yīng)的可靠性經(jīng)濟(jì)性綜合評(píng)估與優(yōu)化軟件,并結(jié)合網(wǎng)架模式可靠性評(píng)估經(jīng)濟(jì)性優(yōu)化模型的軟件應(yīng)用問(wèn)題進(jìn)行分析,實(shí)現(xiàn)對(duì)實(shí)際電網(wǎng)及優(yōu)化改造方案的可靠性經(jīng)濟(jì)性綜合評(píng)估,為城市配電網(wǎng)的可靠提供相應(yīng)的保證;第五章主要是對(duì)本文進(jìn)行了總結(jié),得出了一些具有建設(shè)性的意見,并對(duì)城市配電網(wǎng)后期發(fā)展進(jìn)行了展望,通過(guò)研究結(jié)果的分析,對(duì)未來(lái)的發(fā)展情況和研究方向提出了幾點(diǎn)建議。
[Abstract]:Due to the rapid development of our country at present, the use of power resources in all aspects of society has been expanding year by year.While providing support for large-scale electricity consumption, the state also needs to ensure the quality and safety of power resources. In the process, the relevant departments have started the urban distribution network management system.It can provide a comprehensive management for the use of electricity in various regions. When problems related to energy transmission are found, the distribution network can reflect and propose relative solutions in time.In this paper, the project evaluation and management evaluation of the reliability of urban distribution network are carried out, and some related problems are introduced and explained.The first chapter of this paper mainly carries on the background and the significance research, especially in recent years the electric power load growth obviously speeds up, the city distribution network has become the "bottleneck" which restricts the city development, the electric energy quality,Power supply capacity and reliability can not meet the needs of users, through the current development of urban distribution network process, further research and comparison of domestic and foreign status, determine the content of this study and expected research results;The second chapter is to determine the necessity of economic evaluation of reliability assessment and the economic basis of the relevant calculation methods through the calculation of reliability evaluation methods and related indicators of urban distribution network, mainly from the reference to power supply companies.The concept, method, model, basic data and index system of reliability evaluation of distribution network are given.The premise of reliability evaluation of related grid is assumed, and the analysis results are compared to determine the variables that affect the results. Using the established model, the typical distribution network connection mode is taken as the breakthrough point.The economic and technical analysis of the distribution network structure, which is the key content of the distribution network planning, is carried out, and some general conclusions are drawn on the basis of the simplification of the problem.The fourth chapter is to determine the economic mode of distribution network reliability through the economic optimization model and evaluation research of the urban distribution network reliability evaluation, aiming at the complex and diverse characteristics of the actual distribution network.The software of reliability economy evaluation and optimization is developed, and the software application problem of reliability evaluation economy optimization model of grid mode is analyzed.To realize the comprehensive evaluation of the reliability and economy of the actual power network and the optimization and transformation scheme, and to provide the corresponding guarantee for the reliability of the urban distribution network. Chapter five summarizes this paper and draws some constructive opinions.The future development of urban distribution network is prospected. Through the analysis of the research results, some suggestions are put forward for the future development and research direction.
