Research On Application Of Early Warning Index Of Safety Management In A Power Grid Enterprise

With the expansion of the scale of the grid,the grid operation will be fault or accident,which is affected by equipment transformation,personnel misuse and the natural environment and other factors,affecting the reliability of power supply system.At present,the relevant research system and response system of early risk warning management are not perfect,and the control level of grid safety operation is low,which can't effectively prevent grid safety from accidents.In order to improve the ability of grid enterprises to deal with risks and improve the reliability of power supply,it is necessary to explore and study the early warning system for safety management.Before the accident,it is necessary to prevent preventive measures,minimize the loss,and protect people's life and property security.The main contents of this paper: firstly,the present situation of safety management of power grid enterprises is expounded,including the rural power grid and urban power grid,and then summarizes the problems existing in the four aspects of power equipment,personnel,grid regulation and natural disaster by combing the present situation.The mechanism is analyzed.Then,according to the four aspects of the existence of the problem,four secondary indexes including equipment risk,personnel risk,grid risk and environmental risk are established according to the principle of scientific,systematic,important,flexible and operable.Then,the early warning model of safety management of power grid enterprise is established.The expert rating method is used to evaluate the early warning index.The fuzzy Analytic Hierarchy Process(AHP)method is used to determine the weight of the early warning index.The multi-objective linear weighting function is used to determine the final safety status of the grid enterprise.And through the establishment of the early warning signal system,the use of different police stations in the indicators of management strategies,the impact of early warning model analysis.And then the A grid enterprises is regarded as an example for the empirical analysis.Finally,some countermeasures and suggestions are put forward for the safety management of power grid enterprises,which can provide reference for the development of safety measures in power grid operation.Based on the analysis of the present situation and existing problems of the safety management of power grid enterprises in China,this paper applies the safety management early warning index of A grid enterprise,constructs the early warning model and puts forward the positive and effective prevention and response measures,which can effectively reduce the probability of accidents in the operation of powergrid system.The research of this paper has certain practical significance to the safety management of power grid enterprises in China.
