Abstract

The invention provides a method and system for evaluating the running state of an intelligent electric energy meter. The method comprises the following steps: firstly, constructing a plurality of Bayesian networks based on historical data; calculating the similarity between the Bayesian networks, selecting a plurality of Bayesian network individuals with high precision and strong diversity, and finally integrating the selected Bayesian networks by adopting a convex function evidence theory method to obtain the probability value of each operation state of the intelligent electric energy meter.According to the method and the system, the state evaluation of the intelligent electric energy meter is accurately realized, and great convenience is provided for the safe operation, state monitoring, data reading, electricity price issuing and other work of a power grid, so that the huge cost of periodically recovering and detecting the electric energy meter is effectively saved, and a powerfultechnical guarantee is provided for replacing the intelligent electric energy meter.

Description

technical field [0001] The present invention relates to the field of electric energy metering, and more specifically, relates to a method and system for evaluating the operating state of a smart electric energy meter. Background technique [0002] Smart energy meters are gradually entering every household to achieve complete coverage of electricity consumption information collection, and its important role in the construction of smart grids is being highlighted. The service life of smart energy meters is limited, and the verification cycle of class 1 and level 2 active energy meters is generally less than 8 years, which means that each energy meter will be taken back for testing after 8 years of use. If it can still be used, it will also go through the cumbersome process of "two dismantling and two reinstalling", and it will not exceed 2 years to be used again. Therefore, the current recycled smart energy meters are all scrapped, resulting in a great waste of resources. If ...
