Research on Defect Identification of Building Power Supply and Distribution Lines Based on Bayesian Reasoning
[Purposes]As the core component of building electrical system,the safety and reliability of building power supply and distribution lines are directly related to the safety and normal operation of buildings.Through the research on the defect identification of building power supply and distribution lines,the potential problems in the lines can be found and dealt with in time,so as to avoid the occur-rence of electrical accidents and ensure the safe and stable operation of building electrical system.There-fore,a defect identification method of building power supply and distribution lines based on Bayesian reasoning is proposed.[Methods]This paper calculates the line resistance,power factor and voltage loss,so as to extract the characteristic parameters of building power supply and distribution lines.According to the characteristic parameters and Bayesian inference algorithm,the defect candidate areas of building power supply and distribution lines are divided,and the maximum posterior probability defect classifica-tion in all events is calculated,so as to realize the defect identification of building power supply and dis-tribution lines.[Findings]The designed method can accurately identify the defects of power supply and distribution lines in buildings with high accuracy.[Conclusions]The designed method can find and deal with the potential problems in the line in time,thus avoiding the occurrence of faults and ensuring the stable operation of the power system.
