| Abstract: | The calculation accuracy of theoretical line loss for 0.38 kV rural distribution networks is influenced by many factors, such as the complexity of rural networks, three-phase unbalanced currents, massive data of operation to be collected, even the imperfection of calculating methods, etc. In this paper, these factors were discussed in detail with the calculation of theoretical line los- ses by the equivalent resistance method for several countryside areas powered by a transformer respectively. Some measures were proposed for reducing the line loss base on the reality of rural networks,and the corresponding effect is analyzed by removing the transformer to the loads center. |
