Distribution power reconflguration is realization of distribution power recovering. The target is not only to recover power supply immediately for the non-trouble area, but also meet the capacity of the line load, the least wire lose, the least operating steps, keeping lines balance and the highest reliability. At present most researches focus how to separate trouble quickly and how to recover the non-trouble area. Few researches discussed selecting optimized recovering path. The problem to realize distribution power recovering is a new task in the distribution power field. Examples prove it is a simple, fast, practically and efficient method to select the best path to recover the non-trouble area with dynamic programming and non-linear multi-object technology.
