SCADA Interface for Pumping Station

11/11/2009 12:47 AM

thanks for helping me

i'm a junior engineer in electrical field we will desgin a pumping station consists of big substation and 4 transformers and 24 big pumps with MCC (DIRECT ON LINE) and now i'm asking about the electrical signals like MCCBs switches ...etc should interface and configuring on the SCADA system form the electrical equipments

THANKS TO EVERY ENGINEER IN THIS GREAT SITE

Re: what the electrical signal should be interfaced to scada in pumping stations

Create an I/O count:

  • How many digital inputs?
  • How many digital outputs?
  • How many analog inputs?
  • How many analog outputs?

That describes the number of connections are needed. Review the available equipment and go from there. The rest is about making sure the I/O is compatible with the drive circuits for all those transformers and pumps.

Hi Notone8,

PWS starts you in the right direction. I/O count is essential to define the capacity and functionality of the system Also consider the graphics side when working through the logic statements. SCADA kit gives the designer many options that would be extremely difficult and/or costly to obtain by hard wiring alone.

Trending and data retention intervals are fundamentals of the programs and different suppliers should be carefully compared to get the best fit for your application.

Think about 'self proving' I/Os because these will alarm even when not in active use and therefore improve the reliability of the system.

Good luck,

Massey.
