Abstract
Taking 500 kV Shaping substation as an example
this paper analyzes the limiting effect of various schemes
as well as the influence on the grid structure and security and stability level. Short-circuit current limiting method should be selected according to the actual situation of power system. On the basis of ensuring that the short circuit current does not exceed the standard
the security and stability level of the power grid and the power supply ability are guaranteed.
