Abstract
Abstract: In order to make the backup power supply device can work properly, we study the influence of distributed power substation on automatic bus transfer. Based on the systematic analysis of distributed generation technology, different types of DG are discussed and analyzed, and the corresponding results are obtained. At the same time, the corresponding solution is given. The results show that the anti-islanding device can be installed in the inverter grid DG. In addition, the original line protection can be changed into full- speed fiber longitudinal differential protection. The monitoring device can also be mounted at the switch to detect the voltage, current, and power direction. Finally, a substation backup power supply based on DG access was developed.
