Research on reliability assessment method of electric power communication network and application

In order to guarantee the smart grid construction and the safe and stable operation, research of the reliability evaluation method, and has important theoretical and practical value. Series, parallel, redundancy, voting, series-to-parallel/parallel-to-series, no series parallel/ no parallel series, spare, beside al redundancy and complex network or some combination of system reliability model, through mathematics abstraction, establish reliability logic relationship, reliability model of electric power communication network. Comprehensive node traversing algorithm and the formation of orthogonal method of path tracking algorithm, through the path tracking algorithm method algorithm reliability block diagram (RBD) model algorithm. And the development of the electric power communication network reliability assessment software_NetReliable, year 2003 - 2010 operation situation of electric power communication network and the historical records of fault, the Guangdong electric power communication network reliability assessment analysis. And put forward to improve the reliability of the Guangdong electric power communication network suggestion.
