Abstract

The invention provides an online monitoring system and method for an intelligent electric energy meter, and particularly designs an on-line monitoring and data acquisition system and method based on adistributed acquisition system, transformer area configuration information and same-type reference information in comparison with the prior art on the basis of the technical requirements of parameteracquisition and error correction of the intelligent electric energy meter in the operation process. Meanwhile, considering that errors of the intelligent electric energy meter may come from various aspects such as measurement errors, light-load errors influenced by creeping performance, sampling errors of a sampling circuit and attribution errors, the invention provides a multi-angle comprehensive online monitoring system and method for the intelligent electric energy meter by performing normalized configuration on ternary verification information, and compared with the prior art, the systemmonitoring performance and the electric energy meter parameter acquisition effect are especially good.

Description

technical field [0001] The invention belongs to the field of information technology of a new generation of intelligent internet of things, and in particular relates to an online monitoring system and method of an intelligent electric energy meter. Background technique [0002] In today's smart grid deployment, the smart meter is one of the basic equipment for data collection of the smart grid (especially the smart distribution network). basis for information presentation. In addition to the basic power consumption measurement function of traditional electric energy meters, smart meters also have two-way multi-rate metering functions, user-side control functions, and two-way data communication with multiple data transmission modes in order to adapt to the use of smart grids and new energy. Function, anti-theft function and other intelligent functions. [0003] As early as the 1990s, the concept of smart meter (smart meter) appeared. When the static meter first appeared in ...
