Research on Weibull Distribution Optimization Based on Residual Life Prediction of Electric Energy Meter
In this paper, a remaining useful life model of watt-hour meters based on Weibull distribution is proposed. The maximum likelihood function of Weibull distribution is estimated by genetic algorithm. The reliability function of residual life of a batch of watt-hour meters is determined, and the relationship between residual life and reliability is finally calculated, which can be used to quantitatively analyze watt-hour meters in a certain year. The remaining life of age is of great guiding significance for large-scale maintenance and rotation of electric energy meters.
