With the construction of the electricity information collection system, a more comprehensive data basis has been provided for line loss analysis. The maximum function of the electricity information collection system is to collect real-time electricity from the concentrator (main meter) and the collector (sub meter), and through data sharing with the line loss management module in the SG186 marketing system, it can calculate real-time line loss in a timely and accurate manner, ensuring the timeliness and accuracy of line loss calculation, completely freeing up the manual and complicated work of line loss statistics and analysis in the substation area, and providing great convenience for the correct statistics, scientific analysis, and targeted rectification measures of line loss in the substation area.

The construction of the low-voltage substation line loss training system is based on the electricity information acquisition system and the line loss simulation device as the carrier. By simulating various faults that form line losses, it simulates the generation of management and technical line losses. Through training and competitions, it improves the ability of practitioners to analyze and judge the causes of line losses and eliminate faults, and enhances their technical level.

The low-voltage substation line loss training system consists of three main parts: line loss simulation master station, line loss simulation device, and on-site maintenance tools.

　1) Line loss simulation master station:Can collect data from all terminals and electricity meters on the simulation device; Manage all aspects of the training process, including training, exams, competitions, and assessments; Set up faults for all meters and collection terminals on the device, and generate various line loss faults.

　　2) Line loss simulation device:Including various collection terminals and electricity meters, responsible for collecting and providing raw electricity information of the electricity collection system, forming various line loss faults.

　3) On site maintenance tools:The on-site maintenance tool includes two parts: an intelligent testing tool for collecting electricity information and a substation identification instrument. By using an intelligent testing tool for collecting electricity information, it is possible to accurately verify and troubleshoot various fault phenomena that occur in the collection equipment; Use a substation identification device to determine the substation relationship of the collection terminal.

The collection mode covers a comprehensive range

The simulation device adopts a dual (single) surface design, with each surface simulating one platform area. One simulation device consists of one transformer simulation device and several user simulation devices. The user simulation devices are divided into 485 acquisition mode and carrier/small wireless acquisition mode. Usually, one simulation device consists of one substation simulation device, one 485 acquisition user simulation device, and one carrier/small wireless acquisition user simulation device, covering the existing electricity information acquisition modes and simulating the entire line loss from the substation area to the user.

Comprehensive business simulation

Fully in line with the business process of handling line losses in the low-voltage substation area, comprehensively simulate various faults that affect line losses from the substation area to users, and complete training on the workflow of each link from system analysis to on-site fault investigation.

Easy to operate

1) Flexible and convenient file configuration

The terminal meter parameters do not need to be configured through the GPRS channel. The simulation master station directly configures the terminal meter files and fault distribution solutions to the simulation training cabinet through the Ethernet channel with one click buttons. The simulation training cabinet automatically configures the corresponding meter parameter files to the corresponding terminals.

2) Flexible and convenient fault configuration for managing line loss

The simulation main station provides a question bank for faults that cause management line losses. Questions are selected from the question bank to form test papers, which correspond to the cabinet table to form fault distribution plans. These test papers can be used as exam papers and training distribution plans.

3) Automatically synchronize fault data

When there is a fault in the procurement system, the meter data, terminal measurement point data, and main station line loss related data need to be adapted to the corresponding fault. It is necessary to generate daily frozen data for terminals and meters based on the corresponding faults, and send the corresponding terminal measurement point data to the simulation master station to form fault data display.

The formation of fault data between terminals and meters does not require cross day operations or the use of GPRS calling from the main station. After the simulation training main station issues terminal meter files and fault distribution plans with one click, the cabinet automatically generates corresponding fault meter data and terminal fault measurement point data, and automatically configures them to the corresponding meters and terminals. The simulation device also directly replies the corresponding terminal measurement point data to the simulation master station, displaying it as the required fault data.
