摘要：Using distributed generator is growing due to their advantages in distribution networks recently. But these advantages will be realized when the consequences of their presence in distribution system are fully checked and their disadvantages are eliminated. One of their major impacts is on the protection of the distribution systems. Presence of distributed generator in distribution system makes the grid become non-radial which makes the coordination between protections devices lost. The reason for doing this is to look at the network of events and changes in the DG entrance, so that we can solve the problems. In the subsequent research, we present a solution to this problem. Therefore, it is necessary to provide a new plan to address the problem. In this paper, the problems of DG presence on the traditional protection systems of distribution network is investigated and the DIgSILENT platform is used to simulate the problems of DG presence on protection devices coordination on a test distribution grid as a case study.
