Abstract:In order to improve the security of power network and realize the sustainable operation of power network, deep learning neural network is introduced to design and study the security situation awareness method of power network, and a new security situation awareness method is proposed. This paper uses the power network security situation assessment index, combined with all kinds of power network environmental factors, to predict the possible future power network change trend; After the power network security situation assessment index and related expression meanings are defined, the power network security situation risks are comprehensively quantified. By dividing the power network security situation risk quantification and grade, the power network security situation prediction model based on deep learning is constructed to verify the simulation security situation awareness prediction results. Through the example of real power network, it is concluded that when the new security situation awareness method is applied in the operation environment of real power network, it can achieve accurate prediction of its security level and provide security guarantee conditions for the sustainable operation of power network, which has certain practicability.
