Aiming at the extension of the grid of Xinjiang power grid 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 are proposed. Firstly, the paper analyzes the grid structure of Xinjiang Power Grid. On this basis, it discusses the problem of large regional short-circuit current caused by Xinjiang"s large-scale power-intensive grid, and then optimizes grid operation mode, installs transformer neutral point and small reactance and new limit. The application of the flow device analyzes the current limiting measures, and finally proposes a comprehensive short-circuit current control scheme adapted to the current region. 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.
