摘    要:在不同供电区域负荷密度和不同变电所容量条件下,对中压配电网常见的几种接线模式进行了经济性和可靠性计算分析,研究其随负荷密度和变电所容量变化的趋势,以及在相同条件下不同接线模式之间的比较。基于定量计算结果,经综合考虑,给出了有指导意义的建议方案:在可靠性要求很高的区域例如城市繁华中心区,建议采用电缆接线的不同母线环网接线(三座开闭所)模式或不同母线出线连接开闭所接线模式;在可靠性要求较高的区域例如一般城区等,建议采用电缆接线的不同母线出线的环式接线模式或架空接线的三分段三联络接线模式;在可靠性要求不是很高的地区例如城郊等,建议采用架空接线的不同母线出线的环式接线模式或不同母线三回馈线的环式接线模式。

关 键 词:中压配电网    接线模式    经济性    可靠性

Abstract:Under the conditions of different load density of power-supply areas and different substation capacity, economy and reliability of some familiar connection modes for distribution systems are calculated and analyzed to get their trends with load density and substation capacity varied. The difference between these connection modes under the same condition can also be known from the comparison result. Furthermore, based on quantitative analysis and synthetic consideration, some useful schemes are proposed. For the areas where high reliability is needed such as the urban flourishing, cable-link different buses loop connection mode or feeders from different buses connection to substations mode is suggested. For the urban ordinary where reliability is less than above, cable-link feeders from different buses loop connection mode or line-link three-fraction three-tie loop connection mode is suggested. For the suburban districts where reliability is not very necessary, line-link feeders from different buses loop connection mode or three feeders from different buses loop connection mode is suggested.
Keywords:MV distribution systems  connection mode  economy  reliability
