Integrating DMS and GIS The Time Has Come
Geogmphic Information System(GE)
The DMS must build an initial connectivity model of the as-built distribution network from data available in the GIS. The DMS also needs the ability to easily recognize changes to the as-built network and update the connectivity model to reflect those changes, without impacting current operations. The GIS also provides the geographic location of the distribution facilities, along with reference landbase data. h may also contain one-line schematics or other circuit diagrams required by DMS users. Ideally, all data in the GIS should be available to as needed to users of the DMS.
The GIS will often also include customer connection information, either via a customer of transformer relationship, or more often via direct connectivity (secondary network, service cables, meter locations, etc.). The DMS must be capable of extracting and maintaining this information in order to correctly associate customer trouble calls with the location of each customer in the network.
Finally, DMS users must have the ability to indicate permanent changes in the electric network. These permanent changes should be reflected in the GIS database so that mappers and design engineers are aware of the current position of devices in the field.
Customer Information System(CIS)
TheDMS must be able to accept customer trouble call information from the CIS. These will either be entered manually by customer service representatives (call takers) or automatically using an Interactive Voice Response (IVR) system. Most calls will include a unique customer identifier that links the customer into the DMS network model. The system also must handle non-customer calls in an appropriate manner.
The customer service representatives and IVR would like to obtain current outage status information from the DMS as individual customers call in (e.g., expected restoration time). The DMS must also be able to generate customer call lists for planned outages or customer callback lists to help verify outage restorations.
