A new substation configuration algorithm based on the graphic characteristic of the main electrical connection

Abstract

In order to overcome some disadvantages of the conventional adjacent matrix method, the relationship between the elements of the adjacent matrix and the connected routes among nodes is analyzed as the fundamental introduction. Subsequently, the graphic characteristic of the main electrical connection in power plant or substation is extracted as three types: single branch, two branches in-parallel and multi-branches in-parallel, and an unified principle for the formulation of connected routes among arbitrary two nodes in wiring connection is also proposed as the cornerstone for the novel method. Thirdly, a novel method of substation configuration is established based on the set of connected routes among arbitrary two nodes, and by mean of taking the route state as variables, the value of connected routes set is used to directly determine the element in corresponding place of the adjacent matrix. Finally, the example results show that the new method is able to finish the original topology analysis and track the state status of switches more accurately and rapidly.
