| Power supply reliability refers to the ability of the power supply system to supply power to the users.With the development of information technology,it is an inevitable trend that the power supply reliability management of distribution network turn to micro power supply reliability management.Distribution automation is a necessary means to improve the reliability of power supply,and the macro guidance of distribution automation system is regional planning,while from the microcosmic view,differentiation design of distribution automation configuration should be according to the demand of user-oriented power distribution reliability.This paper discusses the evaluation method of the power supply reliability of distribution network management,and study the comparison between macro and micro methods of power supply reliability of distribution network,pointing out the main way to enhance the regional macro and micro power supply reliability,expounds the necessity of carrying out the research of power supply reliability.This paper establishes a distribution line for power supply reliability demand model of distribution automation terminal differentiated configuration through simplifying the structure and feature extraction of the distribution network,and the distribution terminal differentiation collocation is studied,and proves the distribution automation terminal differentiation configuration is reasonable and practical.Finally,for area power reliability target,this paper researches some key technologies of distribution automation system construction,and put forward the regional difference design method,and gives a design example of distribution automation system in a coastal city,gives a description of the method. |
