Design and Research of distribution network firewall protection terminal

distribution network firewall,topology analysis,fault location,"hand in hand" circular distribution network

In order to decrease the influence of failure occurred in the distribution network, and improve the reliability, proposed a design of the distribution network firewall protection terminal in this paper. Statements are described in detail, including the overall architecture of the system, the communication protocol, the systematic workflow, and distribution network topology analysis, as well as fault location algorithm. The firewall applied to "hand in hand" circular distribution network to analyze faults. At the same time, the firewall which used STM32F417 as the core has been successfully applied to somewhere, until now it has shown the advantages of stable operation and superior performance, finally demonstrated the effectiveness of the firewall terminal.
