| The power supply reliability is the foundation of the modern electric power industry,and it is the synthesis manifest of the plan,the design,the construction,the equipment manufacturer and the productionof distribution network.At present,the domestic study for the reliability of electric distribution network mainly concentrates in the domain of mid-voltage and hign-voltage.To the electric power,the result of the research is not satisfied and can not comprehensive reflect the actual situation of each kind of the user.So the distribution network reliability is a need of the improving quality,and it is the basic guarantee of the equipment security and economic operation.With the development of social economy and pepple's life quality,the requirement to the electric energy quality has been more and more rigorous.Power supply interruption will not only cause economic losses of industrial and agricultural production,but also have an effect on people's lives and social stability.Power supply reliability is a major indicator of measuring the ability of continuous power supply.the essential objective of the research on distribution system reliability is to provide safety,reliable electric power to customers and gain the maximum benefit for society.According to the construction and reform,reliability technology and management level of the city and countryside power grid in Yunfu.The weakness of power grid structure and technological management has been analyzed.Also,the measures in management and technology has been put forward for improving the reliability of power supply,every measures hans been break into every year,clearly responded to every departments and the assessment indicators have been defined.With the rapid economic development and growth in demand for electricity in Yunfu,it is necessary to solve the problem in the development ,but also the left by history in power grid construction.To improve the reliability of power supply in a relatively short period,a number of measures and a comprehensive treatment will needed.Through systematic analysis and the weakness of power grid, effective improvement strategies are proposed based on the factors that effet reliability,The hign starting point plan,hign-quality construction,making an integrated interruption management and a fine blackout process control,optimizing workflow,enhancing cutting and supplying power transmission,transfering power and the management of electricity equipment,making full use of new technologies,new methods,improving power supply reliability rate and raise the level of the overall plan and construction,operation management,technical innovation.Which provide a reference for the power supply bureau to develop program on improving power supply reliability.
