Abstract:The statistics of the user power supply reliability indexes are large in volume, and this makes it easy for the Chinese power service department to make mistakes. This leads to statistics and data that cannot be reported timely and accurately. To solve such issues，this paper has designed the special plotting platform for distribution network adopting graphics technology, implemented the simulated manipulative operation, employed the automatic numbering technology of distribution equipments stratifica the searching technology of a distribution network, and recorded correlation information automatically. This system use the function of the calculation of index for user power supply reliability, the statistics of user power supply status, and the management of equipment statistics to obtain the integrated management of distribution equipment graphics and correlation data. The system adopts C/S network architecture to accomplish remote data sharing. When applied in experiments, results verify that the system has perfect functions, a strong interaction, an accurate computation, and an operation that is reliable, flexible, and instant.
