中文摘要:

本文提出了一种基于Weibull分布的电能表剩余寿命模型,采用遗传算法对Weibull分布的极大似然函数进行参数估计,确定了某批次电能表剩余寿命的可靠度函数,并最终计算出剩余寿命-可靠度的关系,可定量分析电能表在一定年龄下的剩余寿命,对电能表的大规模维护、轮换工作具有很强的指导意义。

英文摘要:

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.
