Study On Countermeasures For Prevention And Control Of Large-scale Blackouts In Anshan City

Power system security is a key issue of concern in the world in recent years.Many countries,such as Brazil,India,the United States,Ukraine,etc.,have even experienced large-scale blackouts in the country,causing serious economic losses and social impacts.Therefore,the safe and stable operation of the power grid is crucial.Analysis of the causes of large-scale blackouts and the development of a reasonable and effective emergency management system can reduce the occurrence of large-scale blackouts and is very important for social stability.This paper takes Anshan City Power Grid as the research object,analyzes the large-scale power outage events at home and abroad,and combines with the characteristics of Anshan City Power Grid to identify seven major risk sources inside and outside Anshan Power Grid.Combined with the excellent research results at home and abroad,the risk assessment theory is better combined with the large-scale power outage response work of Anshan Power Grid.Construct a scientific and reasonable grid risk analysis and evaluation index system,use fuzzy analytic hierarchy process to analyze and evaluate the large-area risk indicators of Anshan City,and find the hidden danger factors that threaten the large-scale blackout crisis of Anshan Power Grid.The emergency management system for large-scale blackout incidents with government as the main body was constructed,and the main emergency tasks at each stage were summarized and summarized,and suggestions were made in the technical support and emergency response of emergency,in order to solve the large area in real life.The blackout event provides a theoretical basis.
