安居工程中压配电网接线模式探讨

Study on MV Distribution Connection Modes of Comfortable Housing Project

目前安居工程的电网规划尚未形成有效的规划方法,因此对安居工程配电网接线模式的研究极有价值。采用改进的层次分析法从经济性、可靠性、电能质量等方面对单电源辐射接线模式、不同母线出线的环式接线模式、双电源双T接线模式、不同母线出线连接开关站接线模式、3-1主备接线模式等七种典型中压配电网接线模式进行了综合评价。安居工程和普通小区规划结果的算例分析表明,该方法适合安居工程的中压配电网接线模式。

There is no effective planning method for comfortable housing project at present. Therefore, the research on its distribution modes is highly significant. Based on advanced analytic hierarchy process（AHP）, seven kinds of typical MV distribution connection modes such as radial connection mode, ring connection with two sources, dual-power dual-T connection mode, switch substation with two sources, ＂3-1＂ connection mode are evaluated comprehensively from the aspects of economy, reliability and power quality. Finally, an example is presented to obtain the planning results of comfortable housing project and common residential area. The results show that the proposed method is fit for MV distribution mode of comfortable housing project.
