Abstract |
The distribution system supplies power to customers, and the reliability of the supply accordingly is very important. Therefore, the need for a protection system to continuously supply power through automatic correction of protective device has been important. The method of automatic correction for the protective device according to the distribution system topology change in various conventional papers requires a long simulation time or additional facilities. However, if the proposed method in this paper is used, the changed system topology can be determined using a graph search method, and through this, the protective device correction value can be automatically set according to the order of the protective device. |
