Failure-rate Data Acquisition of Power Equipments Based on BP Neural Network

Acquisition of the basic parameters of power system's reliability depends on long-term statistic and calculation.The stability evaluation for a new project needs relative basic stability parameters.In the case of lacking such parameters it is obliged to use the existing statistical parameters of other projects indiscriminately.This paper gives a method to obtain failure-rate parameters of power system equipments using BP neural network,taking into account various factors that have influence on failure rate.This method can be used to obtain the failure-rate parameters of power equipments needed for stability evaluation of a new project on the basis of the existing credible failure-rate parameters of power equipments in the areas where difference in influence exerted by various factors on failure rate is not significant.
