The distribution gis data management methods and its application in distribution running are systematically researched , which compose distribution gis network topology analysis ( nta ) and optimal rush - maintain path ( orp ) , and distribution planning , which composes distribution spatial load forecasting ( slf ) : ( 1 ) with systematic analysis on the relationship between spatial data model and spatial data structure , the distribution feature and the two common gis data models are analyzed , which are vector and raster data models . then the conceptual and logic data models of distribution gis are designed . the spatial data storage structure is given by using vector method , and their detailed data management methods are proposed
（ 4 ）將gis的空間信息分析功能應用于配網(wǎng)空間負荷預測（ saptialloadforecasting ， slf ）的研究：綜合利用灰色理論及遺傳規(guī)劃的優(yōu)點，提出了一種根據(jù)饋線的歷史峰值負荷進行外推的組合slf法：首先采用負荷轉(zhuǎn)移耦合法來修正負荷歷史，消除由于負荷轉(zhuǎn)移引起的誤差；然后根據(jù)實際饋線路徑和配網(wǎng)gis圖形分層，運用圖層疊加分析得到饋線的實際供電范圍；接著采用灰色關聯(lián)度聚類方法對饋線負荷增長曲線進行聚類分析；最后采用遺傳規(guī)劃來對灰色聚類結果進行符號回歸，分別得到每一類曲線的最佳擬合曲線形式。
