Abstract

The invention provides an electric energy meter reliability detection method and device. The electric energy meter reliability detection method comprises the following steps of: acquiring failure rate data of each element in an electric energy meter according to a failure rate prediction model; acquiring connection relationship information of each element and a bus of the electric energy meter; generating a reliability function of the electric energy meter according to the failure rate data of each element and the connection relationship information; and generating and outputting detection data comprising electric energy meter reliability information according to the reliability function of the electric energy meter. Compared with the prior art, more accurate electric energy meter reliability assessment results can be acquired by means of the invention.

Description

technical field [0001] The invention relates to an electric energy meter, in particular to a method and device for detecting the reliability of an electric energy meter. Background technique [0002] The smart energy meter (electric energy meter) is an electronic energy meter designed and manufactured according to the State Grid Corporation's enterprise standard Q / GDW 364-2009 under the requirements of the State Grid Corporation of China to build a "smart grid". Monitoring, automatic control, information interaction and other functions. The reliability of smart energy meters is related to the realization of the goal of smart grid construction. Quantitative evaluation of the reliability of smart energy meters is conducive to mastering its reliability level and further evaluating the various risks brought about by its network operation. [0003] Reliability, as one of the important indicators to evaluate the quality of electric energy meters, is the key to ensure that the per...
