Selection and Quantification Method of Status Evaluation Index of Electric Energy Meter

Abstract

The invention discloses a watt-hour meter state assessment index selection and quantization method. According to the working principle and operation features of the watt-hour meter, an electric energy metering device online monitoring system such as a power utilization information acquisition system newly promoted by the national grid is combined, assessment indexes are extracted from three aspects of basic information, operation monitoring and operation state information, index selection is wide and complete, classification is distinct, and the operation state of the electric energy metering device can be comprehensively reflected. In addition, influences on the watt-hour meter by each index are researched, technical specification documents related to electric energy metering and management by the national grid are consulted, a corresponding index quantization standard is determined, and quantitative state assessment on the watt-hour meter is facilitated.

Description

technical field [0001] The invention relates to the field of state evaluation of electric energy metering devices, in particular to a method for selecting and quantifying state evaluation indicators of electric energy meters. 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. The fairness and reasonableness of business billing involves the economic interests of the electric industry department and user...

Problems solved by technology

However, this inspection method often only judges the state of the electric energy meter through the on-site operation indicators of the metering device, and the evaluation system is slightly single, which cannot systematically reflect the state of the metering device from many aspects.

On the other hand, many impact indicators of electric energy meters lack a clear and specific quantitative standard, making it difficult to quantitatively judge their impact in state assessment
