【摘要】：智能變電站是堅(jiān)強(qiáng)智能電網(wǎng)的建設(shè)基礎(chǔ)和重要組成部分。智能變電站采用先進(jìn)的傳感技術(shù)、控制技術(shù)和網(wǎng)絡(luò)交換技術(shù),是變電站自動化技術(shù)發(fā)展的重大變革。智能變電站的建設(shè)和改造是未來發(fā)展的方向。全球范圍內(nèi)唯一公認(rèn)的智能化變電站網(wǎng)絡(luò)傳輸標(biāo)準(zhǔn)就是IEC61850,它的推出主要是用來處理智能變電站內(nèi)部工ED相互之間的配合問題。IEC61850針對用戶建立模型,通過分層次的映射進(jìn)行各層次間的通訊,采用統(tǒng)一標(biāo)準(zhǔn)的操作指令,以及體系工程方法等先進(jìn)的數(shù)字化及通信手段思想,通過上述方法構(gòu)建智能化變電站整體一致的信息和通信平臺。 現(xiàn)階段智能變電站的建設(shè)主要停留在對IEC61850標(biāo)準(zhǔn)及相關(guān)工程建設(shè)規(guī)范細(xì)節(jié)的驗(yàn)證、實(shí)現(xiàn)階段,而對于變電站保護(hù)及自動化的功能實(shí)現(xiàn),無論在原理上還是在技術(shù)體系上,都基本沿襲了傳統(tǒng)綜自系統(tǒng)的構(gòu)成,智能變電站信息共享的優(yōu)勢尚未得到充分發(fā)揮。隨著智能電網(wǎng)的大力發(fā)展,越來越多的智能變電站投入使用,雖然針對于傳統(tǒng)變電站的二次系統(tǒng)檢修技術(shù)已趨于成熟,但對于智能變電站的二次系統(tǒng)檢修還處于探索實(shí)踐階段,細(xì)致的檢修規(guī)程的檢修技術(shù)還不成熟,需要在工程驗(yàn)收和檢修過程中積累經(jīng)驗(yàn),制定標(biāo)準(zhǔn)檢修流程,為智能變電站健康運(yùn)行和全壽命周期管理保駕護(hù)航,為堅(jiān)強(qiáng)智能電網(wǎng)的運(yùn)行奠定根基。 本文對智能變電站以及IEC61850標(biāo)準(zhǔn)的應(yīng)用進(jìn)行分析,并通過智能變電站新站驗(yàn)收工作對智能變電站二次系統(tǒng)檢修技術(shù)進(jìn)行探索總結(jié),比較與常規(guī)變電站二次檢修技術(shù)的不同之處,特別總結(jié)了智能變電站自動化系統(tǒng)現(xiàn)場檢驗(yàn)方案,以由傳統(tǒng)變電站逐步改造為智能變電站的220kV章丘變?yōu)槔?總結(jié)改造過程中解決的檢修技術(shù)問題,特別對智能變電站單一裝置檢修時(shí)需要執(zhí)行的二次安全措施進(jìn)行探討。通過基于IEC61850標(biāo)準(zhǔn)的圍繞智能化變電站的二次系統(tǒng)檢修等關(guān)鍵技術(shù)開展研究,對智能化變電二次系統(tǒng)檢修工作方面有重要意義。通過智能化變電站二次系統(tǒng)檢修技術(shù)研究以及工程實(shí)踐,也能為后續(xù)關(guān)鍵技術(shù)的研究提供借鑒,同時(shí)為今后實(shí)現(xiàn)變電站智能化步伐提供有力的技術(shù)支撐。
[Abstract]:Intelligent substation is the foundation and important part of the construction of strong smart grid. Intelligent substation adopts advanced sensing technology, control technology and network exchange technology, which is a great change of substation automation technology. The construction and transformation of intelligent substation is the direction of future development. The only accepted standard for intelligent substation network transmission is IEC61850, which is mainly used to deal with the problem of the coordination of the Ed in intelligent substation. IEC61850 builds a model for users. Through hierarchical mapping, the communication between different levels is carried out, and advanced digital and communication methods, such as unified standard operation instructions, system engineering methods, etc., are adopted. The whole information and communication platform of intelligent substation is constructed by the above method. At the present stage, the construction of intelligent substation mainly stops at the stage of verifying and realizing the details of IEC61850 standard and related engineering construction specification, but for the function realization of substation protection and automation, whether in principle or in the technical system, The advantages of information sharing in intelligent substations have not been brought into full play. With the rapid development of smart grid, more and more intelligent substations have been put into use. Although the secondary system maintenance technology for traditional substations has become mature, the secondary system maintenance of intelligent substations is still in the exploration and practice stage. The maintenance technology of detailed maintenance rules is not mature, so it is necessary to accumulate experience in the process of engineering acceptance and maintenance, to formulate standard maintenance flow, and to protect intelligent substations from healthy operation and life-cycle management. For the strong smart grid operation laid the foundation. In this paper, the application of intelligent substation and IEC61850 standard is analyzed, and through the acceptance work of intelligent substation, the secondary system maintenance technology of intelligent substation is explored and summarized, and the difference between the secondary maintenance technology of intelligent substation and that of conventional substation is compared. In particular, the field inspection scheme of intelligent substation automation system is summarized, taking 220kV Zhangqiu, which is transformed from traditional substation to intelligent substation, as an example, the technical problems of maintenance and repair are summarized in the process of transformation. In particular, the secondary safety measures needed to be carried out in the maintenance of a single unit in an intelligent substation are discussed. Based on the IEC61850 standard, it is of great significance to carry out the research on the secondary system maintenance of intelligent substation based on the key technologies such as the secondary system maintenance of intelligent substation. Through the research of the secondary system maintenance technology and engineering practice of intelligent substation, it can also provide reference for the research of the following key technology, and provide the strong technical support for realizing the intelligent step of substation in the future.
