Abstract

The invention provides a method for detecting the service life characteristic of an intelligent electric meter. The method comprises the following steps of firstly, establishing a first electric meterreliability prediction model according to a component stress method; meanwhile, establishing a second electric meter reliability prediction model according to on-site historical data of the intelligent electric meter; obtaining a reliable life model of the intelligent electric meter through the first intelligent electric meter reliability prediction model and the second intelligent electric meterreliability prediction model so as to obtain the reliability prediction result of the intelligent electric meter; then, establishing a multi-stress degradation model and establishing a mathematical relationship between the stress factor and the service life characteristic of the intelligent electric meter; and finally, taking the reliability prediction result and the service life prediction result as evaluation indexes and carrying out service life analysis on the deviation of metering errors within the service life period of the intelligent electric meter so as to obtain the service life characteristic of the intelligent electric meter. According to the method, a reliability manual is utilized, the on-site historical data are also utilized, and the reliability and the service life of theintelligent electric meter are analyzed so as to obtain the service life characteristic of the intelligent electric meter.

Description

technical field [0001] The invention relates to the technical field of smart electric meters, in particular to a method for detecting life characteristics of smart electric meters. Background technique [0002] In recent years, smart grid has become the energy development strategy of countries all over the world, and smart meter is one of the necessary equipment in the construction of smart grid. With the development of science and technology, while adding electronic components to smart meters to make them more intelligent and convenient, it also makes the structure of smart meters more complicated, and the failures caused by them also increase. [0003] At present, in terms of the reliability and life of smart meters, the traditional method is based on the reliability manual and uses the component stress method to conduct research. This method relies too much on the reliability manual and does not consider the comprehensive impact of environmental stress, so it is difficul...
