Scenario construction and emergency response of large-scale power outages in universities
As a unique community,universities are more sensitive to large-scale power outages.Such e-vents not only affect teaching and life,but also may threaten the safety and stability of universities.In order to comprehensively explore the impact of large-scale power outages on the safety and stability of universities and emergency response strategies,firstly such four types of influencing factors as human,technology and equipment,system design,and natural environment were summarized by analyzing re-cent large-scale power outages in domestic and foreign universities.A power system impact model was established from four levels:power grid,infrastructure,service guarantee and social impact,and the in-tegrity and vulnerability of the university power system were analyzed.Then,combined with Hall's three-dimensional structure theory,a scenario analysis model for large-scale power outages in universi-ties was constructed from such three dimensions as risk evolution,event classification and emergency response to realize the classification and hierarchical interpretation of the key events,scenario disposal and emergency tasks of large-scale power outage events in universities.Finally,based on the power out-age event of a university in Xi'an,the feasibility of scenario construction analysis model and emergency tasks was verified.The results show that the key events during different time periods can help to identi-fy key vulnerable points in the emergency response to large-scale power outages in universities,and the scenario construction analysis model and emergency tasks are feasible.The research results can provide reference for universities to effectively deal with large-scale power outages and ensure campus security and stability.
