Aiming at the extension of Xinjiang power grid framework and the commissioning of a large number of power sources, the short-circuit current of the busbar is increasing continuously, and some areas even exceed the rated breaking current. The short-circuit current limiting measures adapted to Xinjiang area are proposed in this paper. Firstly, this paper analyzes the grid structure of Xinjiang Power Grid. On this basis, it discusses the problem of large regional short-circuit current caused by large-scale power-intensive grid in Xinjiang, and then, the current limiting measures are analyzed from the aspects of optimizing grid operation mode, installing small reactance of transformer neutral point and new current limit device. Finally, a comprehensive short-circuit current control scheme adapted to the current region is proposed. The results show that under the premise of considering applicability and economy, the comprehensive management scheme proposed in this paper effectively solves the problem of short-circuit current exceeding the standard in the development process of Xinjiang Power Grid.
