Abstract: With the rapid development of the new power system, it presents a multi-directional coordination and flexible interaction form of source grid load storage, which also puts higher requirements on the interaction efficiency and level of the customer side. The data acquisition scheme based on traditional power line carrier technology cannot meet the increasing demand for substation business functions and minute level data acquisition. To achieve real-time data collection at the minute level, this article improves the traditional data collection scheme and designs a highly reliable minute level collection scheme by optimizing the collection model and strategy. Through on-site testing and verification, this plan has significantly improved the efficiency of electricity information collection, providing important data support for the increasing demand for substation business. It is of great significance in promoting the digital and intelligent development of electricity information collection systems and equipment, enhancing the ability of two-way interactive electricity services and user experience.
