摘   要
 隨著電力體制改革的深入發(fā)展，人們對(duì)電能質(zhì)量的逐漸重視，供電情況的綜合評(píng)估和經(jīng)濟(jì)管理已經(jīng)受到電力部門和用戶的廣泛關(guān)注。評(píng)判電網(wǎng)供電情況的優(yōu)劣情況就能夠從宏觀上直接反映出供電合理配置的情況，為以后的電力規(guī)劃和發(fā)展提供更好的改進(jìn)依據(jù),對(duì)電網(wǎng)的量化管理具有重要的現(xiàn)實(shí)意義。
 本文將模糊綜合評(píng)判模型應(yīng)用于對(duì)居民小區(qū)日常供電情況的評(píng)價(jià)，通過參考相關(guān)文獻(xiàn)并聽取專家的意見，選取了“技術(shù)合理性”、“運(yùn)行安全性”、“供電可靠性”和“經(jīng)濟(jì)效益性”四類總共20個(gè)指標(biāo)作為評(píng)判的因素集，以“優(yōu)秀”、“良好”、“一般”、“較差”和“很差”五個(gè)評(píng)語建立評(píng)判集。本文采用層次分析法來確定權(quán)重，根據(jù)判斷矩陣，得到了各級(jí)指標(biāo)的評(píng)判矩陣，再對(duì)將評(píng)判結(jié)果組合作為新的評(píng)判矩陣，對(duì)居民小區(qū)日常電力供應(yīng)情況進(jìn)行評(píng)判。
 通過編制MATLAB，同時(shí)結(jié)合Excel進(jìn)行計(jì)算，由合成算子的不同而得到的四個(gè)模型的應(yīng)用結(jié)果表明，四個(gè)模型的評(píng)判結(jié)果一致為“優(yōu)秀”，該模型評(píng)判結(jié)果符合實(shí)際情況，具有一定的現(xiàn)實(shí)效用。
 在設(shè)計(jì)小區(qū)供電模糊控制系統(tǒng)時(shí)，應(yīng)用Zadeh模糊推理理論，用模糊集來描述實(shí)際不確定性的運(yùn)行情況。根據(jù)模糊IF-THEN規(guī)則給出供電的相關(guān)隸屬度函數(shù)，將集合模糊化，經(jīng)過Zadeh推理機(jī)推理得到輸出集合，由重心解模糊器將模糊集合轉(zhuǎn)化為實(shí)值數(shù),完成整個(gè)推理過程。

Abstract
 With the further development of the electricity system, people are more and more emphasis on power quality, Comprehensive eva luation of electricity supply situation and the economic management has been the electricity sector and the user's attention.eva luation of strengths and weaknesses of power supply situation can directly reflect the rational electricity supply situation and provide a better basis for improved for electricity planning and development in the future.It has practical significances in the Quantitative management of the electricity.
 The fuzzy comprehensive eva luation model is applied to the situation of daily electricity supply on the residential area in this paper.By referencing to relevant literature and expert advice it selected the "technical rationality", "running safety", "reliability" and "economic benefits" of these four that those are a total of 20 indicators as eva luation factors set,then established a set of five reviews eva luation-"Excellent", "Good", "General", "Poor" and "Bad".It choosed AHP to determine weights, Obtained at all levels of eva luation matrix according to Matrix, then organized of eva luation results as a new eva luation matrix to judge the daily electricity supply situation on the residential area.
 Through using MATLAB to program and using Excel to calculate，the four models by different Composite operators obtained the same results-“Excellent”. The eva luation results are in keeping with reality and have Practical utilities.
 Designing the Fuzzy control of residential electricity supply system,Using Fuzzy sets to describe the operation of the actual uncertainty on Zadeh fuzzy reasoning.According to fuzzy IF-THEN rules,obtaining the membership function related to electricity supply, then fuzzy the sets , get the output set By Zadeh inference and turn the Fuzzy sets into real numbers by Ambiguity focus device.
