This paper designs and implements a stable, high-performance and secure real-time data acquisition system for distribution network. The data acquisition system completes the data communication module which supports the standard IEC61870-5-104 protocol and improves the traditional data acquisition method of poll according to the actual environment of the distribution network to ensure the efficiency...
With the rapid development of computer technology and application, the information system of power grid scale is more and more big. The relevant data of grid operation become more and more. The operator is facing all sorts of massive data and huge workload. Compared with the traditional form of text and charts, graphical display has irreplaceable advantages in readability, usability, appearance and...
An optimal coordinate operation control method for large-scale wind–photovoltaic (PV)–battery storage power generation units (WPB-PGUs) connected to a power grid with rated power output was proposed to address the challenges of poor stability, lack of decision-making, and low economic benefits. The “rainflow” calculation method was adopted to establish the battery cycle life model and to calculate...
Remote desktop access is typically used for remote access to the corporate network servers, workstations, while bring convenience, it has also brought on the security issues in the audit. In this paper, a proxy-based security audit system is provided.it can effectively monitor the operation and maintenance of the RDP, VNC, X11 session, while providing the replay function for the operation and maintenance...
