摘要：
In the smart grid, the requirement for business collaboration and exchange of data between multiple grid dispatching and control systems is increasing. But the problems such as prolonged and difficult maintenance exist in the practice of data forwarding based on protocol transmission method between multiple grid dispatching and control systems. There is a pressing need for a more efficient and convenient wide-area real-time data transmission mode. On this basis, the limitations of current data acquisition mode are analyzed. A wide-area data acquisition scheme based on power dispatching data network is proposed. The wide-area data acquisition frame and network structure are discussed. The data subscription mechanism, data issuing technology and data acquisition agent method in the wide-area environment are deeply studied. After experimental verification, the wide-area data acquisition can enhance the connection between multiple grid dispatching and control systems, provide more efficient wide-area data interactive means, and improve data transmission efficiency and system usability. © 2019 Automation of Electric Power Systems Press.
