| Abstract: | Some characteristics of rural low-voltage distribution network are described and the theoretical line loss is calculated by the method of equivalent resistance on the basis of deeply collecting the data about some eight typical areas of the Linxiang rural low-voltage distribution networks.Moreover,the influence of the three-phase unbalanced loads on the theoretical line loss in rural low-voltage distribution network is investigated.Some parameters are comparatively analyzed and selected that will be applied to the calculation of theoretical line loss by the method of equivalent resistance.Finally,some suggestions are proposed about reduction of line loss in rural low-voltage distribution network. |
