摘 要:傳統(tǒng)中壓配電網(wǎng)電壓等級評價方法往往會導(dǎo)致在一些負(fù)荷密度發(fā)展較快的區(qū)域選擇了不當(dāng)的中壓電壓等級。提出了一種可以適應(yīng)各種負(fù)荷發(fā)展情況的中壓配電網(wǎng)電壓等級全生命周期評價方法。基于傳統(tǒng)評價方法與經(jīng)驗設(shè)計了全生命周期評價的綜合指標(biāo),并根據(jù)指標(biāo)與實際需求構(gòu)建了中壓配電網(wǎng)等級全周期評價模型。使用該評價模型得出全周期綜合評價指標(biāo),從而比較得出最佳中壓配電網(wǎng)電壓等級方案。使用兩個不同發(fā)展特性的實際區(qū)域數(shù)據(jù)進(jìn)行仿真計算,驗證了該模型與評價方法的有效性,并得出了適應(yīng)各個區(qū)域的最佳方案。

Abstract: The traditional voltage level evaluation methods for medium-voltage distribution network often cause incorrect selection of medium voltage level in areas of fast- developing load density, so a life cycle evaluation method of voltage level for medium-voltage distribution network is put forward, which can adapt to various load development conditions. The paper, based on traditional evaluation methods and experience, first designs comprehensive index of a life cycle evaluation. Second, according to the comprehensive index and actual demand, a life cycle evaluation model of medium-voltage distribution network grades is built. Third, the evaluation model is used to obtain comprehensive evaluation indexes of the whole cycle to achieve the optimal voltage level scheme of medium-voltage distribution network. After making simulated calculation of two actual areas with different load development conditions, it is found that this model and evaluation method are effective and the best suitable scheme for each area is achieved.
Key words: medium-voltage distribution network; life cycle evaluation; comprehensive evaluation index system; voltage level
