Network operation due to a fault or load transfer switch in opening and closing, change frequently

Distribution large and complex network structure, the network structure or the load transfer operation due to a fault in the opening and closing of the switch, change frequently. Distribution network analysis as the basis for calculating need to further improve the network topology, there is an urgent need for a good network topology algorithms. Good network topology algorithm should be effective and intuitive, it is not only able to meet the different distribution automation requirements of air circuit breaker, but also to achieve the power distribution network connectivity quickly track and identify, adapt to changing events. Should also save storage space and other electric meter time. At home and abroad the existing research in this area is associated table matrix notation, web-based matrix notation, the node elimination, tree search representation, discrete processing method.
Association table matrix notation, together form the matrix, the device number to analyze the device connections, power transformers obtained. Which created two tables matrix, N line 13 nodes describe matrix and M rows 16 slip description matrix. These two matrices that contains every node and each branch of the associated node or branch number, and their respective properties. Since the complex structure of the distribution network, based on analysis of the associated table search method will be very complicated time-consuming, difficult to achieve fast track network topology.
