Embodiment Construction

[0044] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.

[0045] Such as figure 1As shown, the preferred embodiment of the present invention provides a method for error analysis of metering equipment in the station area, comprising the following steps:

[0046] Step S1: Construct an error analysis subsystem by using an error reference node and all target nodes of its downline, wherein the error reference node is used as the general table of the error analysis subsystem, and the rest of the nodes are used as sub-tables of the error analysis subsystem;

[0047] Step S2: Collect the load data of each node in the error analysis subsystem and identify the start and stop characteristics of typical electrical appliances, and obtain the characteristic value records of the start and stop of typical electrical appliances in each n...

Abstract

The invention discloses a method and system for carrying out error analysis on a transformer area metering equipment, equipment and medium. The method comprises the steps of forming an error analysis subsystem by adopting an error reference node and all target nodes of a line below the error reference node, then achieving characteristic value matching between a target node and the error reference node based on characteristic value records of typical electric appliance starting and stopping in node load data, and for each successful characteristic value matching, and calculating the error deviation degree of the target node relative to the error reference node based on a load change curve of the corresponding starting and stopping time period. Therefore, the error state of each target node relative to the error reference node in the error analysis subsystem can be accurately evaluated, and wide popularization value is achieved.

Description

technical field [0001] The present invention relates to the technical field of error analysis of station metering systems, in particular, to a method, system, device, and computer-readable storage medium for error analysis of station metering equipment. Background technique [0002] The measurement field of electric load is composed of a general meter and many sub-meters. The main meter is responsible for measuring the load of the general node, that is, the entire measurement domain, and the sub-meter is responsible for measuring the load of each sub-node. If there is no error, the measurement of the general meter The value should be the sum of the measured values ​​of the individual submeters. However, in practical applications, there are measurement errors regardless of the total meter or the sub-meters. If the errors of these meters are within a reasonable range, the system is in a normal state of error. If the errors of some meters are outside the reasonable range, the s...
