Research On Application Of Security Risk Assessment In Production And Operation Management For Power Distribution Network

Construction safety risk management system,carry out safety risk assessment of power system,is to avoid and solve the security risk,effective control of various accidents,to promote enterprise safety harmonious development the important topic.At present,when power system reform,three sets of five management systems is initial build crucial period,according to the power system security risk assessment of the status quo,analysis of the security risk evaluation principle and evaluation method and risk assessment in power system operation and production application status.In the power system vulnerability basis for further study on distribution network vulnerability analysis,combined with the actual situation of Yu hang district distribution network,analysis of the distribution network operation management and production safety risk assessment system of various components and key links,and in the analysis foundation,distribution network risk assessment system framework design and programming,in the work,the system practical application,so that the safety risk assessment system can better adapt to the power system reform after the actual demand.The main work of this paper is as follows:(1)The network security risk assessment method basic principle,evaluation process and application status.Passage is mainly about the system of risk factors research of the logical relationships,introduces the basic process of assessment of hazard identification,risk analysis,risk assessment,risk control,so as to control risk,accident prevention,safety purposes.(2)Based on the vulnerability of distribution network security risk assessment analysis,the distribution network is defined as a vulnerability of the system,from the perspective of distribution fault analysis,fault consequences for influence value,analysis of distribution network stability and security risk index.(3)In the Yu hang region distribution network as the model,analysis of distribution network operation and management situation,the weakness and risk,put forward countermeasures of risk prevention and control methods.(4)Analysis of distribution network production management process safety risk,mainly from the people’s unsafe behavior,unsafe condition of things,environmental unsafe factor on three aspects.Give production management key elements of project management,site operations,quality control effect,put forward the risk control measures.(5)Based on the security risk evaluation system and distribution network vulnerability analysis results,the construction of safety production risk assessment system,to project management as the main line,the risk assessment and the annual,quarterly,monthly,weekly production plan organic union;to construct perfect risk assessment database,for more effective risk assessment provides support to achieve production;the field work and the management requirements and risk assessment system of the organic integration,to achieve qualitative and quantitative two aspects of risk assessment,and can realize the coping strategies and control methods of scientific selection;has good expansibility,can support and other management system further integration.For the power system to provide an assistant decision-making means of scientific management,and effectively improves the level of safety management.
