Abstract:

Because the extremely high availability and the characteristics of risk aversion are demanded in electric power communication network, there is great difference between the electric power communication network and conventional communication networks. The minimum loss of credible parameter (MLCP) algorithm has been proposed for the problem that the missing faults can lead to the possibility of power accident. Briefly reviewing and summarizing the symptom of coverage and contribution in classic algorithm, the impact of the fault loss is put more attention to, which is of advantage in power communication network and add the credible parameter to select the hypothesis fault firstly. Simulations show that MLCP algorithm can make the reasonable explanation for the observed symptoms with smaller false positive rate (FPR) and averaging running time of algorithm than other algorithms, without increasing the complexity of the algorithm. The MLCP algorithm is more appropriate to the fault location in the electric power communication network.
