Discussion on the Application of Regional Backup Automatic Switching Device in Bozhou Power Grid

On the basis of the renovation of the original remote backup automatic switching device, a regional backup automatic switching with multiple substation power supplies serving as backup for each other has been achieved. By continuously optimizing and improving the operation logic, discrimination basis, and transmitted information flow of regional backup automatic switching, the function of multiple substations serving as backup power sources for each other can be reliably achieved. Effectively reducing the risk level of the power grid and improving power supply reliability.
