Intelligent low-voltage shunt monitoring device

Abstract

The invention discloses an intelligent low-voltage shunt monitoring device, comprising a data acquisition interface module, a hyperbolic characteristic fitting sampling compensation module, a fault analysis diagnosis and shunt state identification module, a non-contact power consumption monitoring and load prediction module, a function configuration module and a serial port communication module, wherein the data acquisition interface module acquires and stores parameters; the hyperbolic characteristic sampling compensation module performs parameter compensation correction, and then performs shunt fault detection analysis and operating condition identification diagnosis; the non-contact power consumption monitoring and load prediction module performs analysis and prediction; and main control equipment communicates with the function configuration module through the serial port communication module to read and write configuration information and perform transceiving execution on control instructions. The device disclosed by the invention is applied to an intelligent power distribution network, realizes the acquisition of low-voltage branch line loads of end users of the power distribution network and the comprehensive judgment indication of user operating conditions, effectively improves the depth and breadth of information monitoring of a power distribution network system, and improves the reliability of power supply of the power distribution network.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to an intelligent low-voltage shunt monitoring device. Background technique [0002] The low-voltage distribution network is located at the end of the entire power grid, and has the characteristics of wide distribution, complex power supply environment, and difficult operation and maintenance. The 400V low-voltage distribution network covers every street and extends to every power user. It is an important link in the power system to supply and distribute power to users. Once the 400V low-voltage distribution network or equipment fails or undergoes maintenance, it will cause the power system to interrupt the power supply to users, which will affect and cause losses to social production and life. Therefore, how to improve the power supply reliability of 400V distribution network has very important practical significance. [0003] For a long time, the low-voltage di...
