GTH Designs and Implements Wireless SCADA for Local Town
George T. Hall
Company (GTH) was awarded a SCADA project for the rural city of Battle
Mountain, NV in 2012. The scope of work included provision of design
documentation and implementation of wireless RTU equipment with
instrumentation, SCADA master interface and all programming startup and commissioning. The ChallengeThe system as
engineered included a 7 mile stretch between the master SCADA system and
the furthest well site. Each site included a local operator interface
panel. Utilizing Ethernet 900MHz radios it was imperative that we
effectively manage network traffic and still maintain a responsive and
reliable system. The SolutionThe water system
included two separate well sites with 250 HP pumps each running off VFD
control. Each pump was controlled based on draw down of the well to
maintain sufficient well levels while filling tanks and pressurizing
water system. The pumps were backed up with a generator for utility
power fail situations. The RTU’s provided gathered data from the
generator via Modbus for SCADA monitoring. Two storage tanks are monitored via a solar powered RTU that relays tank level and intrusion
status for pump control and monitoring. All of the data from these
three sites is sent utilizing 900 Mhz Ethernet radios from Phoenix
Contact to a master RTU located at the operations building of Battle
Mountain. Wonderware Archestra is utilized for SCADA with tools for
alarm monitoring, report generation and historical archiving.
GTH provided the following documentation & equipment:
- Submittals
- Drawing package with loop diagrams
- Modicon M340 Based RTU’s with Ethernet Radios
- Well level instrumentation
- Flow and pressure instrumentation
- Solar powered RTU equipment
- SCADA software and PC
- Automated backup and report generation
The
GTH Project Manager worked extensively with the contractor, engineer
and end user to develop the SCADA system ensuring successful
implementation in the shortest time possible. |
