Problems solved by technology

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, causing serious waste.

Embodiment Construction

[0046] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0047] The purpose of the present invention is to propose a kind of smart electric energy meter operating state evaluation method based on AHP and DS evidence theory. In order to realize a more accurate evaluation and judgment of the operating state of the smart electric energy meter.

[0048] In order to achieve the above object, the technical scheme adopted by the present invention is as follows: figure 1 shown, including:

[0049] Step 1: Establish indicators for evaluating the operating status of smart energy meters and classification of operating status;

[0050] Step 2: M experts respectively evaluate the degree of influence of each index on the operation status of the smart energy meter;

[0051] Step 3: Use the AHP to establish the weight of each smart energy meter's operating status indicators;

[0052] Step 4: Use the weight value obtained in step 3 to r...

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...
