1、摘要本文以配電系統(tǒng)自動(dòng)化為背景，將地理信息技術(shù)、現(xiàn)代化的計(jì)算機(jī)和通信技術(shù)與電網(wǎng)的管理相結(jié)合，將各種圖形、地圖、數(shù)據(jù)信息統(tǒng)一共享，對(duì)于合理規(guī)劃電網(wǎng)，提高電能質(zhì)量和供電可靠性，具有十分重要的意義。本文介紹了組件式GIS的設(shè)計(jì)思想及其特點(diǎn)，并選定組件式平臺(tái)進(jìn)行二次開發(fā)。配電地理信息系統(tǒng)（簡(jiǎn)稱配電GIS）涉及部門多、軟件規(guī)模越來越大、功能越來越復(fù)雜，這造成程序開發(fā)周期變長(zhǎng)以及軟件的難以維護(hù)，擴(kuò)展原來功能也將面臨更大的風(fēng)險(xiǎn)?；诮M件的開發(fā)方式是解決以上困難的有效途徑之一。組件是二進(jìn)制形式的軟件塊，在軟件設(shè)計(jì)時(shí)，把軟件分成一個(gè)個(gè)相對(duì)獨(dú)立的組件并分別實(shí)現(xiàn)，再把這些組件整合成自己需要的軟件，本文的配電GI
2、S系統(tǒng)就是基于組件技術(shù)來開發(fā)的。本文詳細(xì)闡述了配電AM/FM/GIS的設(shè)計(jì)與實(shí)現(xiàn)，介紹了系統(tǒng)涉及的一些重要概念和技術(shù)，如組件、接口等，重點(diǎn)闡述了系統(tǒng)總體設(shè)計(jì)、系統(tǒng)數(shù)據(jù)庫設(shè)計(jì)與實(shí)現(xiàn)、系統(tǒng)組件層設(shè)計(jì)與實(shí)現(xiàn)等；在此基礎(chǔ)上給出了系統(tǒng)分析和管理技術(shù)的實(shí)現(xiàn)，通過深度優(yōu)先搜索和故障定位專家系統(tǒng)等方法，來完成基于GIS的配電網(wǎng)故障定位和故障恢復(fù)與網(wǎng)絡(luò)重構(gòu)。在文章的最后給出了所設(shè)計(jì)系統(tǒng)的操作界面，并進(jìn)行了項(xiàng)目總結(jié)和展望。關(guān)鍵詞：組件技術(shù)，COM,數(shù)據(jù)庫，SQLServer,AM/FM/GIS,GeoStar,專家系統(tǒng)，配電地理信息系統(tǒng)IIAbstractWiththedevelopmentofthewire
