| Popis: | This paper presents a detailed description of a dynamic zone selection approach for busbar protection using path analysis and graph theory. The main benefit is that the dynamic zone selection logic equations for busbar protection applications are automatically obtained by an offline software-based tool. The method accounts for normal busbar-switching sequences, in-service transfer, bypassed current transformers, breaker substitution, paralleled busbars, and a check zone. The equations can be set up and executed in existing protective relays. The method was tested in a busbar arrangement for different switching scenarios and fault conditions, and the results have proven its effectiveness. |
