A non-intrusive distributed power output monitoring device

Abstract

The invention discloses a non-intruding type distributed power output monitoring device, and the device comprises a sampling interface which is in plug-and-play electric connection with a common connection point interface, wherein the sampling interface carries out the sampling of a power load waveform from the common connection point interface and transmits a result to a comparison module; the comparison module which receives the power load waveform, enables the power load waveform to be compared with a plurality of distributed power typical waveform samples, obtains a distributed power waveform sample nearest to the power load waveform, and enables the nearest distributed power waveform sample to be transmitted to an analysis module; the analysis module which receives the nearest distributed power waveform sample, analyzes the sample, obtains the electric quantity information and auxiliary measurement information, and enables the electric quantity information and auxiliary measurement information to be transmitted to a feedback module; and the feedback module which is used for displaying the electric quantity information for the user, and enables the electric quantity information and auxiliary measurement information to be fed back to a power grid company through a power grid company interface.

Description

technical field [0001] The invention relates to the field of intelligent power supply, in particular to a non-intrusive distributed power output monitoring device. Background technique [0002] Distributed photovoltaic power generation can make full use of the widespread characteristics of solar energy and avoid the site constraints of centralized construction. Traditional distributed power monitoring mainly uses each distributed power matrix to increase monitoring hardware devices, and communicates with each information transmission link to upload information, which takes a lot of time and cost in terms of installation and operation. On the other hand, at present, conventional low-voltage lines do not have the functions of early warning of distributed power supply access ratio and new energy start-stop monitoring, which brings a lot of trouble to the daily operation and maintenance management of lines. [0003] Aiming at the problem that the disorderly and decentralized ac...
