Abstract

The invention discloses a method and a system for calculating the failure rate of an electric meter. The method comprises the following steps of: establishing a probability density function of each child according to a Weibull distribution model; Calculating an overall probability density function according to a preset mixing weight and a probability density function of each child; Calculating anoverall reliability according to the overall probability density function; Calculating An overall failure rate function based on the overall reliability and the overall probability density function. This method can be used to calculate the failure rate of the meter with a variety of stresses.

Description

technical field [0001] The invention relates to the field of electric power engineering detection, and more particularly, to a method and system for calculating the failure rate of electric meters. Background technique [0002] At present, as the proportion of residential electricity consumption increases year by year, smart meters have become the main measurement method for electricity consumption. As an important technical indicator of the reliability of smart meters, the normal working life of smart meters can provide better maintenance or replacement plans for smart meters to prevent failures; at the same time, using the reliability of smart meters as a reference can minimize Unnecessary preventive maintenance to save maintenance costs. Therefore, the reliability evaluation of smart meters is very meaningful. [0003] In the prior art, there are two reliability assessment methods: 1) failure time reliability assessment based on accelerated life test; 2) performance deg...
