Abstract

The invention discloses a method for evaluating the running accuracy of an electric energy meter, which specifically comprises the content of error stability evaluation, running reliability evaluation, potential hazard evaluation and other elements, and is characterized in that error stability evaluation comprises S1 fundamental error verification in a laboratory, S2 running error detection at the field and S3 the same batch error dispersibility; running reliability evaluation comprises S4 the same manufacturer batch return rate, S5 the same batch running failure rate and S6 the running time and environment; potential hazard evaluation comprises S7 family defects, S8 on detection for electric quantity abnormity and S9 online detection for clock abnormity; and other elements comprise S10 user reputation. The method disclosed by the invention classifies according to the elements such as the error stability, the running reliability and potential defects, combines maturely running information systems such as power utilization information acquisition, marketing service application and measurement production scheduling platform, selects ten state variables which can reflect the running accuracy and reliability degree of the electric energy meter, and can carry out accurate and reasonable evaluation on the running accuracy of the electric energy meter.

Description

technical field [0001] The invention relates to a method for evaluating the running accuracy of an electric energy meter. Background technique [0002] Electric energy is an extremely important energy source for the national economy and people's lives, and the degree of electrification and management modernization is an important indicator of a country's development. The characteristic of electric power production is that the three departments of power plant power generation, power supply department power supply, and user power consumption are connected into one system and completed simultaneously without interruption. How to sell and purchase electric energy and how to carry out economic calculations involves many technical and economic issues. [0003] Among them, the accuracy of the operation of the electric energy meter is of great importance. At present, there is no mature evaluation method for the operation accuracy of the electric energy meter at home and abroad. C...
