Given the high winds that blow across the farmlands of West Texas and the area’s ever-changing weather, power outages and disturbances are common threats.
To help provide more oversight of its 4,200-meter service area, Brownfield Power and Light wanted to install a SCADA system in their lone substation, which has two 20 MVA transformers, two main breakers, and two feeder breakers. The new system needed to allow personnel to remotely view real-time power system data and control the substation circuit breakers. The catch? It had to cost less than $50,000 (USD).
Brownfield Power and Light reached out to SGS Engineering to help find the small utility a cost-effective solution that could easily be implemented with their existing equipment.
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.
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 a new SEL-3530 Real-Time Automation Controller (RTAC). The SEL-3530 was chosen for its human-machine interface (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.
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:
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.
