Abstract
Power system reliability is an important index,which directly reflects the quality of electric power enterprise service.In order to manage reliability index effectively,special management system and software system is used to complete historical reliability statistics in electric power system.Since the frequent distribution network transformation generated the big workload of data maintenance in the reliability statistics system and inconsistent data error.According to the present situation,by the help of several enterprises,the author developed a all-graphical reliability statistics system to maintain the power grid data.It made the total workload reduce 70%than that of ever,and effectively avoided the inconsistencies of the data which frequently appeared before,then greatly improved the efficiency of reliability management.Meanwhile,by the application of reliability index for evaluating,prevention and control of the reliability index is realized.
