Evaluation On Emergency Capability Of Natural Disasters In Power Grid Enterprises

With the rapid development of China's economy in recent years,China's economic and living standards have significantly improved,in the daily life of the people,the supply of electricity and the national production-life are closely related.Power as the foundation of China's energy and the national economy,the power supply of the perfect or not directly affect the social production and the people's lives.In recent years,with the changes of social environment and structure,the power grid industry has experienced a variety of dangerous challenges at the same time.On the one hand,due to the continuous expansion of the scale of power grid construction,strengthen regional interconnected power grid,so that there is a threat to the power grid security;On the other hand,due to changes in the environment,it will be an occasional outbreak due to hail,typhoons,floods and other natural disasters caused by power outages,equipment damage and a series of unexpected events.In order to deal with the power grid enterprise emergencies,the power grid of China attaches great importance to the emergency management work,has developed a comprehensive,scientific and systematic emergency guidelines,therefore,it is very important to improve the power grid enterprise emergency ability,a comprehensive emergency system will reduce the loss of unexpected events on the grid companies and people.This study is of profound significance.This paper takes the electric power enterprise emergency ability as the main research content,first described the research background and significance of the research;then according to domestic and foreign research status of emergency,combined with the scope and characteristics of the emergency of power grid enterprises and carry out relevant theory summary;by combing and analyzing the related knowledge theory and combining with the basic information of the high temperature,flood and typhoon,etc.,this article from the power grid emergency in the process of selection of emergency prevention stage,preparation stage,responses stage and emergency recovery phase of these four aspects to do evaluation criterion layer for emergency capability of power grid enterprise emergencies,and the four criteria goals were refined,to build 20 detailed indicators.This paper uses fuzzy AHP analysis to refine index and criterion layer index evaluation level,and the emergency management experts on emergency index weight assessment and analysis,with scientific research methods and practice.Finally,through an example analysis come to the general effect of emergency response capacity and the specific level of emergency work status.In view of this,this paperputs forward the corresponding countermeasures and suggestions in the context of the power grid enterprises,in general,to strengthen the emergency management work,to achieve the goal of improving the power grid emergency capacity.
