Research On Public Security Risk Assessment System Of Urban Power System

With the acceleration of industrialization and the development of high and new technology industry,the economic society is more and more dependent on the safe and reliable electric power.The scale of China’s power grid and the scale of the power exchange are expanding,and the power system is a complex system,and the uncertainty of its operation is becoming more and more serious.In the event of a major power failure,the utility of the power industry and the characteristics of the power system determine the impact of the power grid accident is large,fast,serious consequences.In recent years,the frequent occurrence of blackouts in foreign countries directly affects the development of national economy,which not only causes great economic losses,but also brings great hidden danger to the safety and stability of the whole society.This article from the city public security risk assessment of power system angle,closely around the city power system affect the risk of public security,in-depth research in power supply system,power users and system security management,proposed the risk evaluation index is established and the calculation method of power system,city public safety risk assessment system.Not only can a comprehensive and objective assessment of the risk exists in all aspects of power grid operation,and the operation risk assessment work and improve the whole industry action plan level,taking Huizhou power grid as an example,the application of practical,rationality and practicality of system risk assessment demonstrates the body.
