Research on Cyber Security Defense Technology of Power Generation Acquisition Terminal in New Energy Plant

Improving the cyber security defense capability of power generation acquisition terminals in new energy plants (PGATNEP) is of great significance to the safe and stable operation of power grids. Firstly, this paper analyses the cyber security threats faced by power generation acquisition terminals in new energy plants. Secondly, aiming at the threat of cyber security, the cyber security protection architecture of power generation acquisition terminal of new energy plant is constructed to improve its cyber security defense capability. Thirdly, the threat monitoring technology of power generation acquisition terminal in new energy plant is proposed. The association rules are generated offline based on parallel Apriori algorithm and matched online based on similarity algorithm. Fourthly, based on the results of correlation analysis, risk evaluation index and evaluation model are constructed to realize the risk assessment of power generation acquisition terminal. Finally, based on the evaluation results, the anti-seepage strategies of general and high-risk terminals are constructed respectively, which can effectively improve the information transmission security and protection capability of power generation acquisition terminals, and have strong engineering application value.
