GIS with SCADA MMI

Hi,

Is there a rationale in connecting a GIS system with a SCADA MMI? Is it to be used mainly for better GUI-operator interface capability? Please comment anyone...

Yes, in the utility market, if you have an alarm or leak in a service you want to know the GEO-CODE (three-dimensional space) and TIME (one-dimensional) space.

Ideally, the SCADA system identifies the point in alarm, then dispatches a crew based on geographical location. This provides you better CUSTOMER SERVICE!!!!

GIS provides your SCADA with a GEO-CODE.

In an ideal world, GIS, SCADA, Customer Service and logistics applications are linked together so you can respond quickly and proactively.

Yes, there is a relevance of GIS connecting to SCADA MMI. It is used enhance operator-aiding features in a control centre.We can say this based on our studies of applying GIS with SCADA on a Power Distribution.Automation Project. GIS is applied here for:
-Automated mapping/facilities management of the
distribution network
Under this, a spatial database is maintained for
different assets/facilities & customer information.
Data can be organized in different layers and can
be accessed better

-GIS Integration with MMI can be done for Fault Detection function. On the MMI diagrams, the possible location of faults can be detected.

Both systems need to be logically connected using ODBC over TCP/IP or OLE-DB.

They should on separate LAN's or VLAN's. GIS are graphically intensive and can interrupt the SCADA network with excess traffic.

Generally, a Router/Firewall between the two networks works just fine.

However, some clients have installed GIS Servers with an Ethernet card in for the GIS network,
and an Ethernet card in for the SCADA network. (Two IP Addresses).

Talk I prefer using a Router/Firewall with Intelligent Switching hubs measure the network traffic between the two systems.

The HP Procurve hubs have some pretty neat Prioritization schemes built-in. So you can prioritize your IP addresses.
