Problems solved by technology

[0002] At present, in the power marketing system, the line loss management at home and abroad has always been focused and difficult on the four-point management. The research situation is: 1. Unreasonable power supply lines, uneconomical operation of transformers, unbalanced three-phase loads, The power factor is low and theoretical calculation is difficult; 2. The automation program of electric meter return to phase change is not high, and the abnormal state of electric meter is not reported in time, which requires a lot of manpower and material resources to support; 3. Most of the theoretical line loss analysis software currently used It is an offline theoretical line loss calculation and depends on the computer master station server, and the guidance for loss reduction is low

Abstract

The invention relates to a line loss online monitoring terminal of a low voltage station area, comprising a communication unit, a controller, a memory and a host computer, wherein the controller is directly connected to the smart meter through the power line carrier communication module and collects data in the smart meter, the controller stores the collected data in the memory on one hand and transmits the collected data to the upper computer through the GPRS wireless communication module on the other hand after processing the collected data, and the upper computer processes and displays thereceived data; the controller communicates with the mobile terminal on site through the wireless WiFi module, and communicates with the device with the infrared interface on site through the wirelessinfrared communication interface; the controller communicates with the maintenance device through the maintenance interface, and communicates with the power device on site through the cascade concentrator interface to collect the data information of the power device on site. The monitoring terminal has strong compatibility without affecting the normal operation of the concentrator, is convenient for disassembly and installation by adding an alligator clip into the loop for collection, has strong applicability, and has direct and indirect economic benefits.
