Embodiment Construction

[0039] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0040] A method for orderly reinstalling electric energy meters based on remote calibration of power grid line operation errors, characterized in that: the specific steps of the method are:

[0041] (1) When forecasting the demand for the metering device of the business expansion project, the type of the metering device must first be determined, and when adjusting the demand forecast, the business type needs to be subdivided;

[0042] The historical data of the demand for metering devices of the business expansion project has the characteristics of obvious long-term trends, seasonal changes, cyclical changes, and irregular changes; it is considered that irregular changes have little impact on the demand for metering devices in demand forecast...

Abstract

The present invention relates to an electric energy meter ordered replacement method based on grid line operation error remote calibration. The method comprises the steps of when the demand predictionis carried out on the metering devices of the business expansion projects, firstly determining the types of the metering devices, and when the demand prediction is adjusted, subdividing the businesstypes; gathering and calculating the samples of the historical data to obtain the demand generation probability of the metering devices of different business subclasses, or calculating the demand generation condition probability by the Bayes theorem. By applying the method of the present invention, the whole production process is more ordered, the automatic, intelligent and fine management levelsof the production management are improved, the inventory turnover rate is improved effectively, and the safe stock and cost are reduced.

Description

technical field [0001] The invention belongs to the field of electric energy metering, in particular to an orderly replacement method for electric energy meters based on remote calibration of grid line operation errors. Background technique [0002] Demand forecasting is the operation and management personnel of the metering center analyze the annual and monthly meter demand of measuring instruments and the factors that affect demand changes by mining the historical data of business expansion and new installation, regular rotation, engineering transformation, fault replacement meter and in-transit work order data , design a demand forecast model, conduct annual, monthly and periodic demand quantity forecasts for metered materials, and guide the rational preparation of demand plans. At present, there is still a lack of a systematic method for the orderly replacement of electric energy meters. [0003] After a preliminary search, no similar published patent documents were fou...
