An approach to the integration of GIS and DMS

The fatal defect of existing approaches of integrating geographical information system (GIS) and distribution management system (DMS) is neither of them can meet the demand of real-time when the GIS connects with SCADA. In view of this, the application of OLE automation technology is proposed in this paper, i.e. embedding a GIS application as an object into SCADA. The functions of telemetry, telesignal, telecontrol and telesetting of network elements in field can be implemented into a GIS support platform directly, by means of real-time two-way transmission of data and commands between SCADA and GIS. As a result, it can satisfy the need of optimum time responses and reliability of DMS to a considerable degree. Finally, this approach of integrating GIS and DMS is tested on a district utility of Beijing City in China. The result demonstrates the effectiveness and efficiency of the approach presented in this paper
