Research on Active Defense Technology Based on Power System Network Security

With the continuous development of society, network technology is also progressing rapidly, and with it, a variety of new equipment and systems are emerging, and the sub-base power network is the most connected nodes in the entire power grid, the longest transmission distance and the most important infrastructure, which can directly affect the power plant to the degree of power quality requirements and power plant safety operation issues, which can provide security for the operation of the power grid. The existence of the subbase power network plays an important role in the overall power grid and is one of the indispensable foundations to ensure the normal stability of the network, reliable power supply and economy. The security performance of the base-level power network is directly related to the stable operation of the entire power grid, so it is necessary and important to study the active defense technology.
