This paper shows a method that reconfigures the distribution power system by using branch exchange algorithm. The optimal reconfiguration method calculates line loss and voltage condition in all possible power system configurations depending on line on/off, and it searches for the most appropriate optimal configuration. However, it is not easy to search for the solution for the most appropriate optimal configuration in distribution power system for a short time because there are a number of connection & sectionalized switches in distribution power system and it should comply with the condition of radial operation. Therefore, this research shows the method that not only reduces the whole system loss by using branch exchange algorithm which has the advantage in time, but also complies with the condition of radial operation and the constraint condition of voltage.
