This article studies the implementation scheme of minute level collection of electricity information business. Firstly, the architecture of the electricity information collection system and the process of collecting electricity information data were introduced; Then, the minute level collection capabilities of the main station, concentrator, CCO, energy meter, and STA in the substation area were analyzed, and the data transmission delay of the equipment interface was quantitatively calculated to clarify the bottleneck that restricts the data exchange efficiency of the data acquisition system; Based on this, suggestions have been proposed to enhance the data processing capabilities of the data acquisition system, including improving message processing capabilities, increasing data storage capacity, improving serial communication speed, and increasing concurrency; Finally, the application prospects of minute level acquisition technology in the fields of phase recognition, anti electricity theft, photovoltaic output fitting and prediction are discussed, and the importance and practicality of this technology in power system management are elaborated.
