A COMPUTER-PROGRAM FOR GENERATING POWER-SYSTEM LOAD-POINT MINIMAL PATHS

In reliability evaluation that uses minimal cut-set theory, the deduction of minimal cut-set orders is crucial and depends on all the identified minimal paths associated with the load-point whose reliability indices are desired. An input-reduction programming technique that automates this deduction is presented. The technique can be applied to a network of any configuration and finds its greatest application in complex networks with multiple inputs. The power-system structure in the form of power-arms (termination busbars, branch and protective devices) is the only initial input data needed. The results obtained, in terms of minimal paths and minimal cut-set orders for all the load-points, using the program on a sample power-system compare well with the existing results. The program is compact, modular, easy to use and can be applied to any complex-system to generate minimal cut-sets of the desired orders.
