APPARATUS AND METHOD FOR CALCULATING CONTRIBUTION RATIO OF FAULT CURRENT

摘要

The present invention relates to a fault current contribution factor calculation method and apparatus that can provide by calculating the source-specific contribution to the total fault current flowing into a fault point when a fault occurs in the power system. A plurality of generators, the information input unit for receiving information about the power system and the load transformer and transmission equipment constituting the electric power system of the invention for this purpose; A plurality of generators, transformer and transmission equipment and at least one source of failure, and failure to set up a high advantage to the at least one bus bar of the bus bar setting section includes a power system that is an evaluation object of a load; Fault current flow rate analysis unit for calculating a flow rate by source failure fault current flowing into and advantages set through setting unit failure; And by the failure source-specific fault current inflow it characterized in that it comprises a contribution rate evaluation to estimate the fault current contribution by failure generation source.;
