Abstract
To solve the problem of possible multiple solutions and misinterpretation when solving a model due to uncon-strained values of internal variables in a fault hypothesis,an analytical model for power grid fault diagnosis considering protection logic constraints is proposed.First,through the cooperative relationship of action logic between main protec-tion and backup protection,constraints are established to limit the internal variables in the fault hypothesis,thus screening out the fault hypothesis in line with the actual fault situation.Second,the device channel anomaly alarm infor-mation is introduced to construct a fault hypothesis evaluation function and evaluate the fault hypotheses that satisfy the constraints.The fuzzy set theory and binary particle swarm optimization algorithm are used to obtain the fault hypothesis with the highest satisfaction level,which is further combined with the alarm information to derive the whole fault pro-cess.Finally,the validity and universality of the proposed model is verified through failure examples.关键词
