【摘要】 针对广域后备保护与传统后备保护之间的配合逻辑建模的研究,提出基于Petri网的继电保护建模方案。首先,给出两者之间配合逻辑关系;在此基础上,根据其配合关系建立相应的PN模型并对其模型采用PN矩阵分析法进行分析;最后,在Petri Net Editor软件环境下来仿真所建立的PN模型。得出所建立的模型可以清楚地表达广域后备保护与传统后备保护之间的配合逻辑。更多还原

【Abstract】 Aiming at the study on logical modeling between wide area backup protection and traditional backup protection, a relay protection modeling scheme based on Petri net(PN) is proposed. Firstly, the logical relationship thereof is given. Then, the corresponding PN model is established according to its coordination relationship and its model is analyzed by PN matrix analysis.Finally,the PN model is simulated under the PetriNet Editor software environment. It is concluded that the proposed model can clearly express the coordination logic between wide area backup protection and traditional backup protection.更多还原
