Research on Reliability for Electrical System

Abstract

Specific to the electrical system protection unit, a weighting coefficient method to predict the reliability of the protection unit was proposed. Take the power system as an example, the predicting result for the failure rate of the protection unit was given. The result illustrated that the failure rate of the protection unit predicted with weighting coefficient method is only about one third of traditional prediction method, the reliability prediction of the protection unit based on weighting coefficient method is expected to be a reasonable modification for the traditional component counting method, and the result is more scientific and accurate.
