【摘要】:隨著電能生產(chǎn)規(guī)模的擴大,國民經(jīng)濟總消耗當中能源的損耗比例也在不斷的增加。研究分析電網(wǎng)的能量損耗,查找降低損耗的途徑已經(jīng)成為當今具有重要意義的課題。對電網(wǎng)進行網(wǎng)損計算和降損決策的分析,實施合理的降損措施,減小電網(wǎng)的能量損耗也已經(jīng)成為了電力系統(tǒng)經(jīng)濟運行的重要途徑。本文通過對目前網(wǎng)損計算的國內(nèi)外現(xiàn)狀進行分析,研究了幾種網(wǎng)損計算方法的特點,以遺傳算法為基礎,建立包含潮流約束方程、變量約束及目標函數(shù)的數(shù)學模型,開發(fā)了電網(wǎng)的網(wǎng)損計算和決策分析軟件,通過人機友好操作界面建立電網(wǎng)的數(shù)據(jù)庫,用于對配電網(wǎng)進行網(wǎng)損計算,按照分線、分壓、分器進行查詢和分析,并存儲在數(shù)據(jù)庫。降損管理決策主要包含兩組途徑:基于現(xiàn)有運行方式下的降損分析和擬開展的降損決策分析,通過選擇不同決策得到不同的降損方案。
[Abstract]:With the expansion of power production scale, the proportion of energy consumption in the total national economic consumption is also increasing. It has become an important topic to study and analyze the energy loss of power grid and find out the ways to reduce it. The analysis of network loss calculation and loss reduction decision, the implementation of reasonable loss reduction measures and the reduction of power grid energy loss have become an important way for the economic operation of power system. Based on the analysis of the present situation of network loss calculation at home and abroad, this paper studies the characteristics of several network loss calculation methods. Based on genetic algorithm, a mathematical model including power flow constraint equation, variable constraint and objective function is established. The network loss calculation and decision analysis software of power network is developed. The database of power network is established through man-machine friendly operation interface, which is used to calculate the network loss of distribution network, query and analyze according to the dividing line, voltage divider and divider, and store it in the database. The decision of loss reduction management mainly includes two groups of ways: based on the loss reduction analysis under the existing operation mode and the loss reduction decision analysis to be carried out, different loss reduction schemes can be obtained by selecting different decisions.
