Abstract

The invention discloses a system and a method for forecasting the service life and the reliability of an intelligent electric meter, and belongs to the field of electric power engineering detection. The system comprises a data acquisition unit (100), a data adjustment unit (200), a model building unit (300), a model adjustment unit (400), a calculation unit (500) and a result output unit (600). The method includes the steps: firstly, building service life and reliability indexes of the intelligent electric meter; secondly, building a mathematic model of the intelligent electric meter, calculating component failure rate and calculating a forecasting result by the aid of a failure rate result to analyze the service life and the reliability of the intelligent electric meter. The system and the method can solve the problems of low effectiveness, long test time, poor result consistency and the like of an existing traditional judgment method, and have the advantages of convenience in operation, less errors and economic feasibility.

Description

technical field [0001] The invention belongs to the field of electric power engineering detection, and in particular relates to a smart meter life and reliability prediction system and method thereof. Background technique [0002] Smart meters will be a large number of basic equipment in the smart grid. These devices are directly connected to users, and their life and reliability are common concerns of users and power systems. Reliability is an important technical index to measure product quality. Product reliability provides indicators such as the service life of products and parts and the distribution of faults in the life cycle. [0003] The current reliability prediction methods are generally divided into the following three categories: [0004] 1. Reliability prediction method based on mathematical simulation and analysis [0005] The most widely used of these methods is the component stress method. The basic idea of ​​this method is that all components in the system...
