AI Technical Summary

Technical Problem

In existing technologies, the electrical quantity curve data of low-voltage distribution area users are not collected completely and the timing is inconsistent, which affects the integrity of the data and its subsequent use.

Method used

The master station sends a command to the concentrator to enable the storage curve data. The concentrator then issues instructions to the CCO and STA. The CCO performs clock maintenance and broadcasts time synchronization. The STA performs clock maintenance in real time and reads the electricity meter data according to the parameters. The concentrator uploads data periodically to ensure data integrity and time consistency.

Benefits of technology

This ensures the completeness and real-time nature of the data curves for the transformer substations, avoiding problems such as incomplete data collection and inaccurate timing, and improving data reliability and collection efficiency.

Abstract

The application discloses a kind of based on HPLC communication's transformer area data curve storage control method and device, the method steps include: S01. main station issues STA to store curve data and opens the command and parameter of station;S02. after concentrator receives the opening instruction, to CCO and STA issues opening instruction and parameter;S03. CCO carries out clock maintenance, to STA clock time correction and broadcast sends opening instruction and parameter;S04. STA real-time clock maintenance is carried out, and according to parameter, electric energy meter data is copied and stored;S05. concentrator reads curve data from STA according to preset period and is uploaded to main station according to preset period;S06. when concentrator receives closing instruction, to CCO sends closing instruction, CCO broadcast sends to STA.The application has the advantages that implementation method is simple, acquisition efficiency and data completeness are high, data has time consistency etc.
