Abstract

In view of the problem that the short-circuit current exceeds the standard caused by the gradual strengthenment of the power grid structure

this paper compares the effects caused by different limiting measures

and puts forward the measures of the pull side circuit breakers to limit the short-circuit current

calculates and analyzes the effect of this measure by using PSASP software

and sums up the advantages

generalizability and the scope of application of of this measure. The results show that the measure of limiting short-circuit current by pulling the side breaker of substation can not only avoid weakening the power grid structure

but also reduce the short-circuit current effectively.It is helpful for the dispatching department to arrange the operation mode and the rational allocation on the station planning stage.
