Application Research of Situational Awareness System in Power Network Security Protection
The running state of power network is affected by many factors,which leads to problems such as multiple failures and insufficient stability.In the research process,the security situation awareness system is established from the perspective of power grid security protection,which mainly consists of three modules:situation element extraction,situation understanding and situation prediction.Through theoretical analysis and mathematical modeling,the application method of the system in power grid security protection is described,and the following conclusions are obtained.The power grid security evaluation index system can be constructed in the process of situation element extraction.Situation understanding can calculate the comprehensive assessment value of power network security situation and realize the risk classification.In the stage of situation prediction,preventive management measures can be formulated according to the predicted values.
