摘　　要：With the continuous development of distributed power sources,the number of 10kV small power sources connected to the grid is gradually increasing.It is necessary to pay attention to the relevant protection configurations and fault disconnection methods of their access systems to ensure the safe and stable operation of the local power grid in the region.This paper analyzes the relay protection configuration of a small power source connected to the power grid through an example of a 10kV energy switch station in Shanghai,at the same time,it analyzed how the fault disconnection device operates and how it cooperates with the backup automatic switch to ensure the safe and stable operation of the power grid and small power sources when faults occur on the power grid or small power source side.With the continuous development of distributed power sources,the number of 10kV small power sources connected to the grid is gradually increasing.It is necessary to pay attention to the relevant protection configurations and fault disconnection methods of their access systems to ensure the safe and stable operation of the local power grid in the region.This paper analyzes the relay protection configuration of a small power source connected to the power grid through an example of a 10kV energy switch station in Shanghai,at the same time,it analyzed how the fault disconnection device operates and how it cooperates with the backup automatic switch to ensure the safe and stable operation of the power grid and small power sources when faults occur on the power grid or small power source side.
