Abstract

Provided is an intelligent ammeter reliability prediction correction model building method, comprising the steps of: (1) according to a component stress method, building an intelligent ammeter reliability prediction model; (2) according to field data, building an intelligent ammeter reliability prediction model; (3) comparing the reliability prediction model and the filed data to obtain an intelligent ammeter work failure rate; (4) calculating an error coefficient, i.e., a correction factor; and (5) building a reliability prediction correction model.

Description

technical field [0001] The invention relates to a method for establishing a reliability prediction correction model of an intelligent electric meter. Background technique [0002] With economic development and scientific and technological progress, smart meters, as a part of my country's smart grid construction project terminal, have become more and more complex in structure and function, using more and more electronic components, and causing more failures. The reliability of smart meters is an important characteristic indicator of the quality of smart meters, and various faults and reliability problems of smart meters directly reflect the level of grid network structure, operation management and power supply services. Therefore, how to accurately predict the reliability of smart meters has become an important problem to be solved urgently. [0003] At present, the most widely used traditional method for predicting the reliability of smart meters is the component stress met...
