SCADA System Sheds Light on Texas Utility’s Power System

“The wind always gives us a hard time because, you know, the wind blows here sometimes 70 to 80 miles per hour. You never know what’s going to happen.”
Jeff DavisElectrical Superintendent, Brownfield Power and Light

Solution

Lonnie Teal of SGS Engineering designed a standalone SCADA system that used Brownfield Power and Light’s existing feeder protection relays—SEL-351S Protection Systems—along with an SEL-3530 Real-Time Automation Controller (RTAC). The SEL-3530 was chosen for its HMI capabilities as well as its ability to communicate with other manufacturers’ devices via industry-standard protocols. SEL-3031 Serial Radio Transceivers were also added to the system to provide communication between third-party devices.

Results

Brownfield Power and Light’s new SCADA system came in under the $50,000 budget, and the system was up and running in just four days. Personnel can now perform the following activities remotely from the safety of their office: 

  • Operate the circuit reclosers and circuit breakers.
  • Monitor a circuit that is heavily loaded, and shift the load as needed.
  • Gather, view, and analyze events via the HMI.
“The City of Brownfield ended up with a complete SCADA system for control and real-time data under $50,000. That was the main goal, and thanks to Schweitzer, we were able to achieve that goal.”
