Method for evaluating running status of intelligent electric energy meter

Abstract

The invention provides a method for evaluating the running status of an intelligent electric energy meter, and belongs to the field of detection of intelligent devices. The method comprises: step 1, establishing indicators for evaluating the running status of the intelligent electric energy meter and running status classes; step 2, evaluating the influence degree of each indicator on the running status of the intelligent electric energy meter by M experts respectively; step 3, determining the weight of each intelligent electric energy meter running status indicator; step 4, re-judging the running status of the intelligent electric energy meter by using the weights obtained in step 3 to obtain evaluation results of the M experts; and step 5, fusing the evaluation results of the M experts toobtain a final intelligent electric energy meter running status result. The method realizes more accurate evaluation and judgment on the running status of the intelligent electric energy meter.

Description

technical field [0001] The invention belongs to the field of intelligent device detection, and in particular relates to a method for evaluating the operating state of an intelligent electric energy meter. Background technique [0002] As the terminal equipment of the smart grid, the smart energy meter plays an important role in the construction of the smart grid. At present, the State Grid Corporation of China requires that the design life of smart energy meters is not less than 10 years, while the verification regulations for electronic AC energy meters stipulate that the verification period of level 1 and level 2 meters shall not exceed 8 years, and the smart energy meters that have been used for 8 years need It costs a lot to disassemble and send it back to the laboratory for testing. Even if it passes the test, there are only 2 years of life left. Therefore, at present, qualified smart energy meters are often scrapped, resulting in serious waste. In order to solve this...
