Abstract

The invention provides a method and device for establishing a transmission line on/off switching combination scheme for limiting short circuit current. The method applies to the technical field of power systems, and comprises: setting an initial number k of lines to be switched off and a maximum number kmax of lines to be switched off; determining, for each node to be tested among a plurality of nodes to be tested, a k-self impedance upon switching off k lines; determining, on the basis of the k-self impedance of each of said nodes, k lines that meet scheme requirements and k lines that do not meet scheme requirements; on the basis of a preset step length d, increasing the initial number k of lines to be switched off to k+d; when k+d≤kmax, considering those nodes among the k lines that do not meet scheme requirements as nodes to be tested, and returning to the step of determining, for each node to be tested among a plurality of nodes to be tested, a k-self impedance upon switching off k lines, and then proceeding to the subsequent step; when k+d>kmax or when the current set of nodes to be tested is null, determining that the establishment of the transmission line on/off switching combination scheme is complete. The method and device for establishing a transmission line on/off switching combination scheme for limiting short circuit current allows for an on/off switching combination scheme to be established quickly.
