Abstract

The invention relates to an electric energy meter running state evaluating method. The electric energy meter running state evaluating method comprises the following steps of establishing an electric energy meter running state evaluating model; selecting factors affecting the running state of an electric energy meter as state variables; performing functional unit division on the state variables according to impact categories of the running state of the electric energy meter; according to the characteristics of the state variables, establishing a state variable scoring model and determining evaluating content; according to the scoring model and the evaluating content, computing the evaluated scores of different state variables; computing a comprehensive evaluation score of the running state of the electric energy meter; establishing an interrelation model of the comprehensive evaluation score and the fault rate of the electric energy meter. The electric energy meter running state evaluating method solves the problems of reasonable assessment and correct evaluation of the measurement running state of the electric energy meter.

Description

technical field [0001] The invention relates to the field of instruments and meters, and more specifically relates to an evaluation method for the operating state of an electric energy meter. Background technique [0002] As a statutory measuring instrument, the electric energy meter is responsible for the measurement, storage and transmission of important information such as voltage, current, and electric energy. The accuracy and timeliness of electric energy measurement and information transmission are related to the quality and efficiency of electricity bill settlement between the power company and customers. . For the millions of operating electric energy meters that measure a large amount of electricity, at present, regular on-site inspections are generally used to monitor their operating status. The huge amount of investment in transportation and manpower is difficult to meet the current management direction of reducing staff and increasing efficiency. At the same ti...
