SCADA System Sheds Light on Texas Utility’s Power System

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.
