Abstract: In response to the problem of large errors in alarm content retrieval in the three-dimensional visualization simulation model of substations when directly using multidimensional data-driven topology logic, a research on the design of a three-dimensional visualization simulation model of substations based on loop state reconstruction was carried out. Based on the composition of the substation circuit state, a directed bipartite graph network of the substation circuit state is first output through probability weighting. Then, use Bayesian algorithm to calculate the probability of the occurrence of the substation circuit state. Finally, set the minimum substation circuit state probability and the quasi substation circuit state probability as the judgment basis, and output the circuit state that conforms to the real operating topology logic. The three-dimensional tensor of the substation circuit state is used as the basis for model deployment, and the comprehensive representation of model node features is achieved through simulation graph model integration technology. The test results show that the designed model can achieve efficient retrieval of alarm content based on a complete representation of substation connection and composition information, with corresponding errors stable within 3.0%.
