【摘要】：在國(guó)家電網(wǎng)公司深入推行“三集五大”體系建設(shè)的大背景下,內(nèi)蒙古電力公司于2010年開始大力推進(jìn)新能源項(xiàng)目建設(shè)工作。鄂爾多斯電業(yè)局緊緊抓住此契機(jī),結(jié)合地區(qū)優(yōu)勢(shì),努力開展光伏電站建設(shè)工作。 多年來,鄂爾多斯電網(wǎng)所轄變電站覆蓋范圍廣,風(fēng)能、太陽能資源充足。火電因化石資源的枯竭而無法滿足現(xiàn)代電力的需要。隨著光伏發(fā)電技術(shù)日益成熟和太陽能電池成本的逐漸下降,為滿足本地區(qū)內(nèi)日益增長(zhǎng)的負(fù)荷需求,大力建設(shè)光伏電站已勢(shì)在必行。本文的研究,為鄂爾多斯電網(wǎng)大力建設(shè)光伏電站提供了指導(dǎo)意見和配套解決措施,并可以作為工程實(shí)施的技術(shù)手冊(cè),具有重大的意義。 本文以鄂爾多斯電網(wǎng)建設(shè)光伏電站項(xiàng)目為背景,首先分析了我國(guó)光伏產(chǎn)業(yè)發(fā)展趨勢(shì)、當(dāng)前國(guó)家對(duì)光伏產(chǎn)業(yè)的支持政策、光伏系統(tǒng)并網(wǎng)后產(chǎn)生的影響及解決措施,提出了鄂爾多斯配電網(wǎng)接入光伏系統(tǒng)后需要采取措施減少影響的必要性和可行性。然后分析了內(nèi)蒙古地區(qū)和鄂爾多斯電網(wǎng)現(xiàn)狀、電力需求及鄂爾多斯光伏接入情況。接著對(duì)光伏系統(tǒng)并網(wǎng)后產(chǎn)生的影響進(jìn)行了詳細(xì)分析,以在電壓和保護(hù)方面產(chǎn)生的影響為例進(jìn)行了深入的研究。接下來在影響分析的基礎(chǔ)上,對(duì)鄂爾多斯配電網(wǎng)接入光伏系統(tǒng)應(yīng)采取的措施分技術(shù)方面和管理方面展開了深入的探討,并針對(duì)情況提出了合適的技術(shù)和管理改進(jìn)措施。最后,對(duì)鄂爾多斯光伏系統(tǒng)未來建設(shè)即將開展的工作進(jìn)行了探討,并對(duì)今后光伏系統(tǒng)研究方向和應(yīng)用方向提出了建議。并以宏大光伏電站20MWp金太陽屋頂示范工程接入系統(tǒng)進(jìn)行了實(shí)例分析。
[Abstract]:Under the background of "three sets and five" system construction carried out by State Grid Company, Inner Mongolia Electric Power Company began to vigorously promote the construction of new energy projects in 2010.Ordos electric power bureau grasps this opportunity tightly, unifies the region superiority, diligently develops the photovoltaic power station construction work.Over the years, the Ordos power grid has a wide range of substations, wind and solar resources.Because of the depletion of fossil resources, thermal power can not meet the needs of modern electricity.With the development of photovoltaic power generation technology and the decrease of solar cell cost, it is imperative to build photovoltaic power station in order to meet the increasing load demand in this area.The research in this paper provides guidance and corresponding solutions for the construction of photovoltaic power station in Ordos power grid, and can be used as a technical manual for engineering implementation, which is of great significance.Based on the project of building photovoltaic power station in Ordos power grid, this paper firstly analyzes the development trend of photovoltaic industry in our country, the current national support policy for photovoltaic industry, the influence of photovoltaic system and its solution.The necessity and feasibility of taking measures to reduce the impact after the Ordos distribution network is connected to the photovoltaic system are put forward.Then, the paper analyzes the current situation of Inner Mongolia and Ordos power grid, power demand and the situation of photovoltaic access in Ordos.Then, the influence of photovoltaic system is analyzed in detail, and the effect of voltage and protection is studied deeply.Then, on the basis of impact analysis, the measures to be taken by Ordos distribution network to access photovoltaic system are discussed in detail in terms of technology and management, and appropriate technical and management improvement measures are put forward in the light of the situation.Finally, the future construction of the photovoltaic system in Ordos is discussed, and the research direction and application direction of the photovoltaic system in the future are put forward.An example of the access system for the 20MWp gold solar roof demonstration project of a large photovoltaic power station is presented.
