摘要
Abstract
Digital substation has been widely used in China, but the study of centralized protection algorithms is scarce. This paper proposes a centralized protection adaptive zone selection algorithm based on graph theory. The algorithm modifies real-time topology structure of substation according to equipment state information and topology connection of substation, which forms a real-time Vertex-edge adjacency matrix, and also selects primary protection zone online according to real-time topology structure. The algorithm also selects backup protection zone adaptively if the information received by centralized protection device was missing. The results of calculating examples show that the proposed algorithm in this paper is feasible.关键词
