Low-voltage feeder line three-phase current real-time monitoring system and working method thereof

Abstract

The invention relates to a low-voltage feeder line three-phase current real-time monitoring system and a working method thereof. In recent years, with the increase of the power demand of customers andthe diversification of load structures, the problem of three-phase power load imbalance is brought about, and problems such as the low power factor of a low-voltage line, voltage drop increase, electric energy consumption increase, the shortening of the service life of power distribution equipment, and the increase of the security risks of a power grid are also brought about. The system of the invention comprises a field acquisition module used for monitoring and controlling the three-phase current of a low-voltage feeder line; the field acquisition module is connected with a monitoring center upper computer through a communication interface, wherein the monitoring center upper computer is used for remote real-time monitoring; the field acquisition module comprises a signal acquisition module for acquiring the three-phase current signals of the low-voltage feeder line and a control machine; and the signal acquisition module includes a sensor for collecting UV voltages, and a 0-20 mA input interface connected with the low-voltage feeder line through a current transformer. With the low-voltage feeder line three-phase current real-time monitoring system and the working method thereofprovided by the technical schemes of the invention adopted, the monitoring and scientific analysis of the three-phase current unbalance of the low-voltage feeder line can be realized, and the actualmeasurement and adjustment of transformer load can be facilitated.

Description

technical field [0001] The invention relates to a low-voltage feeder three-phase current real-time monitoring system and a working method thereof. Background technique [0002] In recent years, with the increase of user demand for electricity and the diversification of load structure, due to the geographical location, technical factors and timeliness of management in some distribution areas, there has been a problem of unbalanced three-phase power load, which directly leads to low voltage The power factor of the line is low, the voltage drop increases, the power loss increases, the service life of the power distribution equipment decreases, and the security risk of the power grid increases. It has seriously affected the production and quality of life of users, and brought certain negative effects to enterprises. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the exis...
