An online monitoring system and method for a smart electric energy meter

Abstract

The present invention proposes an online monitoring system and method for an intelligent electric energy meter. Based on the technical requirements of parameter acquisition and error correction during the operation of the intelligent electric energy meter, it is better than the prior art to design a system based on a distributed acquisition system and station area configuration. On-line monitoring and data acquisition systems and methods for information and reference information of the same type, while considering that the errors of smart energy meters may come from various aspects such as measurement errors, creep performance affecting light load errors, sampling circuit sampling errors, and attribution errors, etc., Through the normalized configuration of the ternary verification information, a multi-angle integrated smart energy meter online monitoring system and method are proposed to achieve better system monitoring performance and energy meter parameter collection effect than the existing technology.

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 ...

Problems solved by technology

The smart energy meter itself has a high technical level and is relatively less likely to be damaged. However, in practical applications, it is found that the smart energy meter still has error problems, which affects the accuracy of the application and brings losses. The performance of the smart energy meter, Statistics and monitoring of state, operating parameters and dynamic errors have become an important part of smart grid management
