Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] A comprehensive evaluation method for a portable electricity metering device based on an improved and optimized membership function, comprising the following steps:

[0039] 1) For the portable electricity metering device, first establish its business evaluation index, mainly to evaluate the basic business attributes of the product before delivery and after delivery, including supply pass rate, supply cycle, relative supply price, and maintenance efficiency. When evaluating the business indicators of the portable power metering device, according to the actual situation of the product, the qualification rate of supply can be evaluated at different levels, and corresponding scores can be assigned. The classification of business indicators is shown in Table 1, which includes the indicators for evaluating the basic business attributes of po...

Abstract

The invention discloses a portable electric quantity metering device evaluation method based on an improved and optimized membership function, and the method comprises the steps: carrying out the grading and evaluation of all indexes of an evaluated sample according to a comprehensive evaluation index system of a portable electric quantity metering device, and obtaining original evaluation data; and calculating a membership value of each index data of the sample by using a typical membership function to obtain an improved and optimized membership function of each index, and further calculating the membership value of each index data. When different membership functions are adopted for evaluation in an existing method, obtained mapping results have differences. Meanwhile, due to the fact that each membership function has undetermined parameters, different parameter selection methods can also influence mapping results of the membership functions, and then the credibility of evaluation results obtained under a single membership function is not high. According to the method, the problems of singleness and subjectivity in an existing membership function selection method can be effectively solved.

Description

technical field [0001] The invention relates to an evaluation method for a portable power metering device based on an improved and optimized membership function, and belongs to the technical field of power metering. Background technique [0002] As an important part of the smart grid's advanced measurement system, the energy meter's measurement accuracy is the basis for realizing the reliable, economical and efficient operation of the smart grid. Due to the rapid upgrading of electric energy meters and the quality of electric energy meters themselves, the frequency of electric energy meter replacement is relatively high. In order to improve the quality of service, power supply companies currently widely adopt the method of electric energy meter replacement to ensure that the normal use of electricity by power users does not The premise is affected by the meter replacement, which makes it impossible to measure part of the electricity actually used by the user in the meter rep...
