Abstract

The invention discloses a unified modeling method of multidimensional grid models based on a DMS. The method comprises the steps as follows: S11, object modeling; S11, object-relation database mapping; and S12, metadata model constructing. According to the unified modeling method of the multidimensional grid models based on the DMS, a unified grid model is realized, a complete data platform is provided, a flexible metadata mechanism is adopted, and a service-oriented multilayer system structure is applied, so that sharing of electric power information resources is facilitated.

Description

technical field [0001] The invention belongs to the technical field of distribution network management and relates to a DMS-based unified modeling method for a multi-dimensional network model. Background technique [0002] With the development of urban and rural distribution network construction, the increase of power system capacity, the increasing number of users, and the continuous emergence of new power supply and utilization technologies and equipment, the distribution network is becoming more and more complex. Crossing, spanning, paralleling, Relationships such as branches gradually increase. In the face of such complex topological relationships, it is difficult to guarantee the speed and reliability of power system management only by manual work. The integrated automation system, that is, the Distribution Management System (Distribution Management System), referred to as DMS, its overall goal is to realize the comprehensive automatic management of the distribution ne...
