SCADA

Project Experience
UTEC designed the Greenwood, SC CPW SCADA system. This system includes RTUs at five electric substations, three at natural gas stations, two at gas pressure monitoring stations, and one at the operations center generator. The master station includes four operator stations and one remote operator station.

Design of a link from a 200 MW ICTG site in Monroe, GA, to CP&L’s wholesale trading floor in Raleigh, NC, using 10baseT Ethernet, and TCP/IP over CP&L owned intranet.

Design of a multi-utility SCADA system for the City Monroe, NC. The system serves electric, gas, water, and wastewater utilities. The system includes 41 RTUs. The master station includes a dual master station and five operator stations. Combinations include single mode fiber optics and 900 MHz radio.

Specification of optical transceivers for the City of Georgetown water and wastewater utility.

Design of new communications channels for SCADA and load management RTUs at eleven substations using a T-1 multiplex over optical fibers for the City of High Point, NC Electric Department.

Project Highlights

City of Georgetown, SC - 4 MW Peak Shaving Generation Plant
The project involved expanding the SCADA system to include the monitoring and control of a new peak shaving generation plant. The single mode fiber optic communication network was extended to the plant. A local SEL Real Time Automation Controller (RTAC) was networked to the generator controllers, plant switchgear PLC, fire suppression alarm system, fuel / diesel exhaust fluid monitoring systems, and to the protective control and relaying system. The RTAC concentrated all the plant data and control points into a common DNP data map for interface to the SCADA system. The software system included Intouch Wonderware HMI software and Imperious Smart SCADA Engine TCP/IP addressing software. The SCADA system also included remote control and monitoring of the plant by a smart telephone application.

Easley Combined Utilities, Easley, SC
SCADA system development for six electrical substations. The project involved Survalent Worldview SCADA software configuration, HMI screen development, and network communication using TCP/IP protocol. Field devices consisted of Survalent Scout RTU’s and SEL Real Time Automation Controllers (RTAC). Local HMI was provided using SEL Diagram Builder Software. The SCADA system archived minimum, peak, and average load data is recorded for each distribution feeder. The system provided remote alarm indication by smart phone text messaging and by email transmission.
