Paper Abstract

Distribution grid line loss index is an important indicator of running and managing a distribution grid. A general feature in distribution network is its difficulty in gathering data about structure and operation. Based on its feature, this paper proposed a method for calculating line loss in 10kV distribution grid from the perspective of planning. According to the characteristics of power consumption on different location of the feeder, line loss can be divided into three parts, including the main line loss, the loss of branch line and the loss of distribution transformer. The proposed method achieved quick calculation and component analysis. Distributed coefficient was calculated by analyzing different distributed situation of load on feeder and the equivalent loss power on main line was calculated. Branch line and distribution transformer were equivalent to a resistance located at the head of the line to match the real power consumption. With the data acquirement, accuracy can be improved. Finally, the example of different power supply zone was calculated based on the method. The comparison between the calculated results and technical guidelines of southern power grid indicated the components of the line loss and put forward solutions for loss reduction. The method proposed overcame disadvantage of strong dependence on complete and precise data, which fits for planning work.
