Abstract Low voltage distribution networks and users directly linked to is extremely important link in the power system. However, due to the huge number of low-voltage power distribution and low voltage level, the planning and layout does not pay enough attention to, common area with the same load is not uniform and the RADIUS is too large, class-d power supply low voltage conditions. Based on minimum spanning tree in a graph theory and the theory derived from the shortest, load under certain situations, how to determine distribution transformers installation point, how to plan low-voltage distribution line and other issues were discussed, with a view to bringing the rural area construction to meet user demand, minimizing the initial investment and operation line loss, a win-win goal. Article example shows that low voltage distribution network based on minimum spanning tree layout is simple and practical, it is an effective method for decision of power grid planning.

Key words： minimum spanning tree low voltage distribution network graph theory line loss initial investment
