Intelligent electric energy meter supplier evaluation method

Abstract

The invention provides an intelligent electric energy meter supplier evaluation method which comprises the following steps: selecting a metering performance index and a business index which comprehensively reflect the error condition of an intelligent electric energy meter to form basic influence factors in an evaluation system; Quantifying the basic influence factors according to corresponding strategies according to actual conditions; an analytic hierarchy process is adopted, basic influence factors are converted into a comprehensive index capable of achieving intelligent electric meter supplier evaluation, and an evaluation conclusion is formed for the supply priority of the intelligent electric meter according to the comprehensive index. An existing evaluation method describes the metering performance of an electric energy meter too roughly, a unified reference is lacked when the index priority is measured and influenced, and a comprehensive and fine transverse comparison conclusion is difficult to form. Therefore, the metering performance of the electric energy meter is refined to four dimensions, the business competitiveness of the supplier is comprehensively considered, andby means of an analytic hierarchy process, a plurality of influence indexes are converted into comprehensive scores under a preset priority reference to form an evaluation conclusion of the prioritiesof different suppliers.

Description

technical field [0001] The invention relates to the field of electric equipment evaluation methods, in particular to an evaluation method for suppliers of smart electric energy meters. Background technique [0002] The State Grid Corporation of China has installed more than 200 million smart meters. In the future, the total number of smart meters will exceed 400 million. The demand is huge. Moreover, the energy meter provides the basis for the trade settlement between the seller and the electricity consumer. Any error and failure will affect the fairness of power transactions. Therefore, it is very important to strictly control the supply quality of smart meters. [0003] The State Grid Corporation currently has a set of supplier evaluation system, which has initially realized the quality control of smart meters. However, the current supplier evaluation system only focuses on primary data such as the pass rate of electric energy meters, but there is a huge span between the ...

Problems solved by technology

However, the current supplier evaluation system only focuses on primary data such as the qualification rate of electric energy meters, but there is a huge span between the qualified and unqualified indicators of electric energy meters, so the quality of electric energy meters cannot be evaluated solely on the attribute of pass rate

Moreover, most supplier evaluation systems lack a unified comprehensive index, which is used to comprehensively describe the importance of the impact indicators of smart meters, and with the increase in the number of impact indicators, it is more difficult for existing evaluation methods to make a comprehensive evaluation of smart meters , the benchmarks between multiple evaluations are very different, making the quality evaluation results not objective and precise enough
