Intelligent energy-saving potential and electric energy quality diagnostic device for individual line user

Abstract

The present invention provides an intelligent energy-saving potential and electric energy quality diagnostic device for an individual line user based on double TMS320F2812. The device continuously monitors and records energy consumption data of the individual line user online, and the recorded data is imported to a mobile memory via an external interface, and analyzed in detail by software of a host computer to obtain an energy-saving potential report of the individual line user. On the basis of the newest double-DSP configuration, high-precision A / D sampling technology, large-capacity storage technology and friendly man-machine interaction technology, the diagnostic device employs a scientific measuring means to ensure that electric energy data of the user to be detected is accurately automatically monitored and recorded online in real time; the diagnostic device is characterized by high sampling speed, calculation precision and intelligent level and easy operation; and the diagnostic device has a remote communication function, and thus, can be applied to enterprises information analysis and management systems of a higher level.

Description

[0001] Technical field [0002] The invention relates to the fields of diagnosis of energy-saving potential of dedicated line users and comprehensive management of power quality, in particular to an intelligent diagnostic instrument for energy-saving potential and power quality of dedicated line users based on dual TMS320F2812. [0003] Background technique [0004] Energy saving diagnosis is a preliminary diagnosis aimed at the power consumption of enterprises and the discovery of power saving potential in energy auditing. The goal of electrical safety is of great significance. [0005] At present, the data acquisition system of the large user load terminal of the marketing department of the power grid company has been able to obtain the overall power consumption of the user, but the large user terminal cannot collect the detailed power consumption of the user's internal power distribution system and load. According to a large number of investigations in the early stag...

Problems solved by technology

[0005] At present, the data acquisition system of the large user load terminal of the marketing department of the power grid company has been able to obtain the overall power consumption of the user, but the large user terminal cannot collect the detailed power consumption of the user's internal power distribution system and loads

According to a large number of investigations in the early stage, it was found that most of the internal power distribution systems of large users are only equipped with a small number of electrical analog instruments without any storage function, and only a few advanced large-scale enterprises have relatively complete electrical monitoring and data acquisition systems.

[0006] At the same time, the US Fluke435 and Hiki HOIKI3196 and other power quality monitors used in the market are generally priced at about 70,000 to 80,000 yuan, which is not conducive to the diagnosis of energy-saving potential and comprehensive management of power quality in general small enterprises, so they cannot be well sold in the market. promotion
